How to measure text height/width?

Hi all, i need to load a text file and split the content into groups. Each group must fit into a rectangle of given height and width.
I tried using "wrappingWidth", but there's nothing similar for the height.
Any suggestions?

Use boundsInLocal? Or layoutBounds.

Hi friends,
I have to do display the resolution of an eps file..
I have to use only Java.
Can any body know the eps file format...
I searched through net but I didn't find any best tutorial for that format..
I am able to find the height and width from the eps file..
By just opening that eps file.. I found %%Bounding box height width....as in some post posted by our jive member...
In this way, is there any way to find the resolution..
if any body knows this details.. please post.. Even if you have the file format tutorial post that one..
Thank you.

Flex 4: How 2 Set Application Height/Width with Script?

I am new to Flex 4 and going through the 3 to 4 migration pain.
I need to set the size of my application programmatically. In Flex 3, I did it this way:
mx.core.Application.application.width = theWidth; (equivalent for height).
I can not figure out how to do this with Flex 4. Searched high and low.
Help, please! TIA

You can use this.height and this.width properties.

How to measure pulse height by DAQ card

I want to record pulse signals (fast pulse) and measure their amplitude (height) using DAQ card

:-) I heard that problem before. Is it possible that we disscused this subject some time earlier?
Well, but to your problem. How many counts do you get per second in average? I work/worked at a similar problem to analyse the counts from a 2D-detector. I tried the VI mentioned above but it was never able to analyse 1000 counts per second as a order of magnitude.
Which shape has your pulses? Are they NIM or square shaped? How stable is your underground and of which order of magnitude is it? How fast is your DAQ board? Because according to the Nyquist theorem you will need a sampling rate of approx. 1MS/s to resolve them properly!

Bug? How to add text maxField width

Came across an abnormality when passing values to a page's text field when branching to it.
The defined size for the text field is ignored when returning a filed/value pair when branching to the target page.
Caught me out when passing a 7 char value as there was a single white space when passing 'With these values:&P34_EMPLOYEE_NUMBER. '
It passed 8 characters - the 7 character employee ID and the white space after the '.'. Value then too large to insert into table.
By way of example::
Page 33.
Text field: P33_EMPLOYEE_NUMBER
maxWidth=7
Width = 7.
Can not type more than 7 characters :)
Validation under page processing:
LENGTH( v('P33_EMPLOYEE_NUMBER') ) =7
Page34.
Text field P34_EMPLOYEE_NUMBER
maxWidth = 7.
width=7
assign value 1234567 to P34_EMPLOYEE_NUMBER
Under Branch action:
Set these items: P33_EMPLOYEE_NUMBER
With these values:&P34_EMPLOYEE_NUMBER.##############
Now when page 34 branches to page 33, it will fill P33_EMPLOYEE_NUMBER with the 7 characters in P34_EMPLOYEE_NUMBER AND any other characters added to the items/values.
So Text field P33_EMPLOYEE_NUMBER on page 33 now displays:
1234567############## in a text field of maxWidth 7!

this isn't an htmldb bug. it's a browser issue. in my testing, i'm only seeing this issue in IE and not mozilla/netscape. you can prove it to yourself by creating a static html (not htmldb) page with this...
<html>
{{<INPUT TYPE="text" NAME="mytextfield" SIZE="7" MAXLENGTH="7" VALUE="12345678910">}}
</html>
...as the source. view it in IE and then view it in mozilla/netscape. you'll find that IE's not obeying its maxlength parameter in this case. as a workaround, i suggest you add a validation to your page 33 that checks the length of P33_EMPLOYEE_NUMBER to make sure it's seven.
hope this helps,

Hi Mindaugas,
While uploading using RSTXLDMC. You have to maintain your size of the logo.
Go through below mentioned document.
Upload TIFF files to SAPscript texts
Description
The report RSTXLDMC allows a TIFF graphics file to be uploaded from the file system of the R/3 GUI to a standard text in the R/3 word processor SAPscript. (TIFF is a registered trademark of the Aldus Corporation.)
When uploading, the TIFF graphic is converted either into a black and white raster image (parameter type=BMON ) or as a color raster image with a maximum of 256 colors (parameter type=BCOL).
The black and white raster images ( BMON) can be printed using the following printer types:
PCL-5 printer
PostScript printer
Kyocera PRESCRIBE printer
Device type SAPWIN (with SAPlpd 32-bit as of Version 2.41 for Windows NT or Windows 95)
The color raster images (BCOL) can be printed using the following printer types:
PCL-5 printer with color capability (e.g. HP Color LaserJet). Color graphics are not printed properly on monochrome PCL-5 printers (e.g. HP LaserJet 5), because the printer cannot set the color palette as required and does not perform any gray-level conversion.
PostScript printer (color graphics are automatically converted to gray levels on black and white printers using PostScript) Device type SAPWIN (with SAPlpd 32-bit as of Version 2.41 for Windows NT or Windows 95) During TIFF graphic import, the basic set " Baseline TIFF 6.0 " of the TIFF specification 6.0 is supported.
To maintain compatibility with earlier versions of the report RSTXLDMC, it is also possible to convert the TIFF graphic directly into a black and white raster image for a particular printer type when uploading. These are the three printer types PCL-5 (parameter type=PCL ), PostScript (parameter type=POST) and Kyocera PRESCRIBE (parameter type=PRES ). A raster image uploaded in this manner can only be printed using the appropriate printer type.
Besides TIFF raster graphics, direct printer commands in the respective printer language (PCL-5, PostScript or Prescribe) can also be contained in the file which is to be uploaded (printer macros). They are then transferred to the standard text unmodified.
The graphics are output by inserting the standard text into the document which is to be printed, directly or using an INCLUDE command. The printer commands, which for example draw a company logo on the page, are only output if the print request is processed by the printer driver corresponding to the macro type, otherwise they are ignored. Example: A macro of type PCL is contained in a print request. If the request is output to a printer with type HPLJIIID (to which the driver HPL2 is assigned), the macro data is sent to the printer. If the request is printed on a printer of type POSTSCPT (to which the driver POST is assigned), the output of the macro data is suppressed.
In the standard text, the printer commands are inserted between the HEX ... ENDHEX command lines in hex notation. Various report parameters allow the graphic or printer macro to be placed on the page or at the current text position. Note: When the /:HEX command line which precedes the macro appears in the text, a line break is generally made before the graphic is output. The output of the macro therefore begins in the next text line at the left window border of the current page window, as long as a shift to the right is not specified (see below).
If your own printer macros are uploaded and not TIFF files, you must ensure yourself that the normal (text) output of the driver is not impaired when the printer commands are inserted in the output from the uploaded file. The printer drivers pass the data contained in the file to the printer unmodified, therefore without control over the individual actions this triggers on the printer. For example, syntax errors should not be generated by the PostScript commands (type POST), or form feeds should not be contained in the file (unless this was intended) for PCL-5 (type PCL).
Restrictions:
In general, the output of graphics generated via RSTXLDMC from R/3 is not suitable for mass printing (that is, unless you are using the "Graphic resident on printer" feature): the R/3 spooler has to hold significantly more data in its output files. If the graphics occur several times in a spool request, the data also reoccurs. Apart from this, the network is more heavily loaded in sending the increased volume of data to the printer and the printer output is slowed significantly (varies according to printer model) if raster graphics are output as well as the text.
If your graphics reside on your printer during a printing job, the degree of 'correctness' with which they are printed depends on the amount of memory available in your printer. R/3 print drivers are unable to determine whether the amount of memory available is enough! If one of the graphics that you have marked as resident is not displayed, try reloading the graphic and switching off the parameter "Graphic resident on printer".
When printing black and white graphics on PCL-5 printers, image data is compressed in order to greatly reduce the file size.
The output of graphics and macros on PCL-5 printers, PostScript printers and device type SAPWIN (type BMON, BCOL, PCL, POST) is adapted to the page orientation used, that is if landscape is used instead of portrait, the graphic is also turned when output. This is not the case for the PRESCRIBE printers (type BMON, PRES)! With these printers, the graphic is not automatically turned when landscape is used, but appears on the page in the identical position as for portrait. You are therefore recommended not to output raster images when printing in landscape on PRESCRIBE printers.
PRESCRIBE printers do not support the resolutions 200 and 600 dots per inch when printing raster images.
Not all PCL-5 compatible printers support the resolutions 200 and 600 dots per inch when printing raster images.
TIFF graphics with compression type 2 ("CCITT Group 3 1-Dimensional Modified Huffman run length encoding ") can currently not be imported although this is a component of the Baseline TIFF 6.0 specification for monochrome images.
Color TIFF graphics with full color representation (ie. a lot more than 256 colors) are automatically converted into 256 gray levels when uploading with type BCOL.
When TIFF graphics are converted to black and white raster images (type BMON, PCL, POST, PRES) there is no default simulation of gray levels or colors of the original image on the printer (for example, by using different tones of gray). Each pixel of the original image is converted to a white or black pixel on the printer according to its intensity value.
The parameter "Number of TIFF gray levels" does, however, allow a simulation of gray/colour tones of the original image through levels of gray on the printer, when using type PCL, POST or PRES. This parameter is ignored for type BMON.
The conversion of TIFF graphics can be so time-consuming that it is recommendable to execute the report RSTXLDMC in batch processing. Note: in batch, the file is always read from the file system of the application server (ie. not from the file system of the GUI).
The length of an individual text in the text file is limited. When importing TIFF graphics with very large dimensions, especially if more than 2 gray levels are used, a termination can therefore occur when saving the standard text ("EXPORT_TOO_MUCH_DATA"). This restriction can only be avoided by reducing the TIFF graphics. Note: The display of a raster image in Postscript or PRESCRIBE format needs from two to three times as much space as displaying in PCL-5.
When processing very large TIFF images on PostScript printers, a print termination can occur with PS error message "limitcheck". In this case the internal memory of the printer is insufficient to scale the required raster image. This implementation limit cannot be influenced by changing the report parameters when importing.
Requirement
The file which is to be uploaded can contain the following formats/ commands:
Baseline TIFF 6.0 raster image files. The image information of the TIFF file is converted into black and white/color raster images when uploading. Note: As the TIFF format allows a variety of variants, only a basic set of TIFF 6.0 formats is supported here described in the TIFF 6.0 specification as Baseline TIFF 6.0.
PCL : PCL-5, Hewlett Packard Printer Control Language 5 for HP LaserJet 3, 4, 5 series and compatible printers. The data is output by the printer driver HPL2 only.
PRES: Kyocera PRESCRIBE for Kyocera laser printers. The data is output by the printer driver PRES only.
POST: Adobe PostScript or EPS format (encapsulated PostScript ) for PostScript printers. The data is output by the printer driver POST only. In the upload, one of the end-of-file markers (CTRL-D, hex $04) which may be contained in the PostScript file is not transferred.
For PostScript files which contain a bounding box entry (for example, all EPS files) the macro/graphic can be scaled to a size specified by the user. In this case, a small lead text and trailer are generated by the report for the macro data and inserted in the standard text.
Parameters of RSTXLDMC
File name
Path and file name of the file to be uploaded in the file system of the R/3 frontend (dialog processing) or in the file system of the application server (batch processing)
Type
Way which the data contained in the file is to be converted. Possible values are BMON, BCOL, PCL, POST and PRES. With parameter values BMON and BCOL, a TIFF 6.0 file is expected. This is converted into either a black and white raster image (BMON) or a color raster image (BCOL). These raster images are printer-independent and can be printed using various printer types (see above).
With parameter values PCL, POST and PRES, either a TIFF 6.0 file or a file with printer commands in the appropriate printer langauge is expected. If the file is a TIFF file, it is converted into a black and white raster image for the printer type specified in the parameter. The presence of a TIFF file is recognized automatically. If the file is not a TIFF file, the file contents are regarded as the printer macro of the respective type. Data loaded with type PCL, POST or PRES can only be printed on the respective printer type.
Resolution for TIFF raster images
Resolution which should be used when importing a TIFF raster image, in dots per inch (dpi). If an allowed value is entered here, this overrides the resolution information in the TIFF file. The allowed values are:
75 dpi
100 dpi
150 dpi
200 dpi (not for type PRES, for PCL only HP LaserJet 4,5 series)
300 dpi
600 dpi (not for type PRES, for PCL only HP LaserJet 4,5 series)
Changing the resolution affects the size of the graphic on the printer. If a resolution of 300 dpi is stated in the TIFF file and this parameter is set to 75 dpi, the graphic is four times as big when printed as at the outset.
Note: Kyocera PRESCRIBE printers do not support 200 and 600 dpi resolutions.
Note: Not all PCL-5 printers support resolutions 200 and 600 dpi, for example HP LaserJet 3 series does not, but LaserJet 4 and 5 series do.
Graphic Resident on Printer
Normally, graphics that occur more than once in a printing job (a company logo that appears on each page, for example) are sent to the printer repeatedly each time they are needed. In order to avoid this kind of redundancy, you can select this checkbox on the selection screen. The R/3 print driver then stores the graphic in the printer's memory and the printer retrieves the 'resident' graphic memory every time that re-occurs in your job.
Caution: Whether or not the printer correctly reproduces the graphic depends on the amount of memory available in the printer during the printing job! You should avoid using this feature with color graphics since they take up a lot more memory than monochrome graphics.
This parameter can only be used with types "BMON" and "BCOL".
Absolute positioning
Determines whether the macro/graphic is positioned absolutely or is to be output at the current text position. If this checkbox is selected, the graphic is positioned absolutely (parameters "X-position" and "Y-position" are used), if this checkbox is not selected, the graphic is positioned at the current text position (parameters "Reserved height" and "Shift to right" are used)
Absolute X-position
Horizontal position (space from left border) of the macro/graphic, if absolute positioning is required. This is the parameter XPOS of the HEX command.
Absolute Y-position
Vertical position (space from upper border) of the macro/graphic, if absolute positioning is required. This is the parameter YPOS of the HEX command.
Reserve height automatically
If this checkbox is selected, the system automatically inserts the actual height of the graphic during printing into the subsequent "Reserved height" parameter.
Reserved height
If positioned at the current text position, this parameter specifies the horizontal spacing to be reserved for the macro/graphic, which must not be printed with text from the paragraph. This is the parameter HEIGHT of the HEX command.
Shift to right
If positioned at the current text position, this parameter specifies the space between the left border of the macro/graphic and the left border of the page window. If this value is increased, the macro/graphic is shifted to the right. This is the parameter LEFT of the HEX command.
Unit of measurement for positioning
The unit of measurement in which the position values (X,Y, height, shift) are specified. Possible values are CM (centimeters), MM (millimeters), IN (inches), PT (typographic point = 1/72 inch), TW (1/20 point = 1/1440 inch)
Text title
Comment used for the attribute "Title" of the standard text generated as well as as a comment line in the text itself
Line width
Number of columns to be used in the standard text when generating the HEX...ENDHEX command lines. The default value is 132
Text name
Name of the standard text to be generated. If an * character occurs in the name, it is replaced by the value of the parameter "Printer type". For example, if the entry is ZHEX-IMAGE1-* and the printer type = PCL, the text name ZHEX-IMAGE1-PCL is generated. The default value for the name is ZHEX-MACRO-<printer type>, but the standard text can be named as required (take into account customer reserve). Standard texts are client-dependent!
Note: The name of a standard text can be up to 32 characters long !
Text ID
ID of the standard text to be generated. The default value is ST (general standard texts)
Text language
Language key of the standard text to be generated. The default value is the logon language
PostScript scaling
Flag which determines how the macros/graphics of type POST are handled. If set to 'X', the report expects a PostScript comment line in the file
%%BoundingBox llx lly urx ury (e.g. %%BoundingBox -1.5 0 21.4 14.1)
as present, for example, in all EPS files, in which the dimensions and the position of the macro/graphic are specified (if a bounding box comment is not included, 0 0 1 1 is assumed as the default value). This information is then used by the report to insert PostScript commands which scale the macro/graphic to the size specified in the parameters "Width" and "Height" (listed below).
If the flag is set to ' ' (blank), the PostScript file is transferred to the standard text without any additions (any transformations to the coordinate system used by the printer driver must already be contained in the file).
The flag must be set to 'X' for the import of TIFF files for type POST.
Width according to PS scaling
Required width of the macro/graphic if the flag PostScript scaling is set. Can remain at zero for the import of TIFF files, the size is then determined by the resolution of the graphic.
Height according to PS scaling
Required height of the macro/graphic if the flag PostScript scaling is set. Can remain at zero for the import of TIFF files, the size is then determined by the resolution of the graphic.
If you want to scale the PostScript graphic with these parameters, one of the two values, width or height, can be specified with zero. The graphic is then scaled so that the width-to-height ratio remains unchanged and the original graphic is not distorted.
Unit of measurement for PS scaling
Unit of measurement in which the parameters "Width" and "Height" are specified. Possible values are CM (centimeters), MM (millimeters), IN (inches), PT (typographic point = 1/72 inch), TW (1/20 point = 1/1440 inch)
Number of TIFF gray levels
Number of gray tones which are to be used on the printer for displaying the original image. Note: This parameter is only evaluated when using types PCL, POST or PRES!
Possible values are 2,4,9. With the default value 2, each pixel of the original image is converted either to a white or a black pixel on the printer. With the value 4, each pixel of the original image is converted on the printer with 4 pixels, which simulate 4 different gray levels. With the value 9, each pixel of the original image is converted on the printer with 9 pixels which simulate 9 different gray levels.
Note: With values 4 or 9 the resolution of the image is doubled or tripled. The restrictions on the possible resolutions (see previous parameter) then apply for the resulting resolution.
Output
Individual steps of the upload procedure are logged in the report list generated and, if necessary, errors reported. The uploading of TIFF graphics, in particular, is cancelled if there is a variant which is not supported. A message to this effect is then issued. If execution is successful, the report generates a standard text with the key specified in the parameters. If the standard text already exists, a window appears with a warning before the text is overwritten.

>>if i am rendering html from MemoryStreamor string in webbrowser control in wpf It's not applying this css
Yes it does. If you for example add background-color: yellow; to the stlyle you will see that the page turn yellow:
strHtml = strHtml.Replace("<body>", "<body style=\"-webkit-column-width:800px; background-color: yellow; overflow:visible !important; -moz-column-width: 800px; column-width: 800px; -webkit-column-gap: 0px; -moz-column-gap: 0px; column-gap: 0px; -webkit-column-rule: 0px solid #000;-moz-column-rule: 0px solid #000;column-rule: 0px solid #000; height:800px; ; margin:0px; -moz-margin:0px;-webkit-margin:0px;display:block;\">");
If the styles doen't get applied as expected it is a browser issue. The WebBrowser control emulates Internet Explorer in IE7 rendering mode by default. You will have to change some registry settings to change this behaviour. Please refer to the following
links for more information:

-moz-column-width only works in FireFox for example.
You may also navigate to an actual page and inject some javascript function that for example adds the styles to the body element dynamically or set the style properties of the body element directly:
private void Window_Loaded(object sender, RoutedEventArgs e)
MainBrowser.Navigate(@"E:/Epubs/ePub2_Sample05_Biology_SampleChapter_EN/OPS/ch01.xhtml");
MainBrowser.LoadCompleted += new LoadCompletedEventHandler(webb_DocumentCompleted);
private void webb_DocumentCompleted(object sender, NavigationEventArgs e)
WebBrowser webBrowser = (WebBrowser)sender;
dynamic doc = webBrowser.Document;
//int _scrollWidth = (int)webBrowser.InvokeScript("execScript");
//mshtml.HTMLDocument webDocument = (mshtml.HTMLDocument)webBrowser.Document;
mshtml.HTMLScriptElement script = (mshtml.HTMLScriptElement)doc.createElement("script");
script.setAttribute("type", "text/javascript");
script.innerHTML = "function doSomething(){ /* do something here... */ }";
//add script to the head
dynamic head = doc.getElementsByTagName("head")[0];
head.appendChild(script);
mshtml.HTMLBody body = (mshtml.HTMLBody)doc.getElementsByTagName("body")[0];
body.style.background = "yellow";
//set any body.style property here...
webBrowser.InvokeScript("doSomething");
That's about it as far as WPF is concerned.

Help me Please..? How to change X & Y co-ordinate and height & width selected content...?

Hi Everyone!
          This is Vijay.I'm new baby to Indesign Script.In my office i took one task for indesign, that's i link one image to picture box that image jump from original position.so i copy that picture box and paste in place to new layer and now link the Eps to that box. againg jump that image. actually (manualy) i copy height,width , center X and Y coordinates from old picture box image and Paste in to newly link image. then link image was perfectly sit in position. any one do for Script or any one help me how to do this..Script.

How do I save the width and height of a photo for repeated use?

How do I save the width and height of a picture for repeated use, rather than having to enter it each time in the 'new file' box?
Thanks, Ed Jackson.

It could be that I'm older and have forgotten. I'm now 73 and will admit I have forgotten many things over the years. I have been using Photoshop since Photoshop version 3. And can not really recall which features or changes were made in ever version of Photoshop I have installed. Adobe has added many features over the years. The number of bugs introduce has also greatly increased after CS3. "New Doc Sizes.psp" in your user id preferences is edited using the two buttons in the new document dialog.
As for guide lines in new documents Photoshop CS6 or CC seem to add some for video file presets with guide lines. I do not know how to edit or add guide line to new doc presets. Guide line actions are easy to create. I have also seem some guideline in new documents when I did not expect any perhaps a new bug. Photoshop like most software has bugs. If you do not see Adobe new presets perhaps you copied an old "New Doc Sizes.psp" over Adobe's newer default file or Adobe migrared you presets and wand wiped their presets out. There are bugs. Close Photoshop down and rename your current "New Doc Sizes.psp" in you user id Photoshop cc preferences folder and start Photoshop it will add a dedault "New Doc Sizes.psp" file see if you see Adobe new presets in the new doc pull down when you select video and film...

How to set a minimum width and height for a stage or scene?

Hello,
Does anyone how to set a minimum width and height for a stage or scene?
I tried listening for width/height property value changes and then adjust the width/height if necessary, but that causes unpleasant flickering of the window.
In JavaFX 2.1 beta SDK for Mac OS, the Stage class has setMinWidth() and setMinHeight() functions which work very well.
I'm wondering what's the equivalent way to do that when using the FX SDK for Windows.
Any help is appreciated!
Thanks.

I was wondering how to enforce a minimum stage size with JavaFX 2.0.3.The same flickering way you are currently doing it. See: http://javafx-jira.kenai.com/browse/RT-15200 "Need a way to set the minimum size of a window"

[CS2]How to get the Image Width & Height using JS (ILLUSTRATOR CS2)

Hi,
How to get the Image width & height of an Image using javascript .Im using Illustrator CS2.
Any sample code
Regards
MyRiaz

you can reference the dimensions of a loading image (or swf)
by referencing the target movieclip's dimensions AFTER loading is
complete. ie, use preloader code or the onLoadInit() method of a
moviecliploader listener.

Excel 2007. OLAP pivot. How do you resize dropdown width and height?

Excel 2007. OLAP pivot. How do you resize dropdown width and height?

hi,
I'm afraid we can't modify that property in Excel. Someone had suggested to use a custom combo box to replace the built-in drop-down. However it will lose the features which are only available
for built-in drop-down.
Hope this
thread will give you some ideas. Thank you.

How can I measure the full width half max pulse-width of a gaussian function?

Hi I am measuring a laser pulse using a Tektronix scope and feeding that data into my labview (v 7.1) based data system on a Mac OS X computer. I want to measure the full width pulse at half the maximum peak. The included measurement VIs that come with labview and the tek scope dont seem to do the job (even though the scope itself can do the measurement). I've attached my example VI. If anyone has any suggestions that would be great.
Thanks,
Paul

If you can display a trace on the screen, you can get the full width at half maximum. LabVIEW gives you several options:
Use the Pulse Parameters VI to determine the width directly. This will be a width based solely on the data with no assumption as to an underlying model.
Use the Levenberg Marquardt VI to fit a gaussian to your curve, then calculate the full width at half maximum from the coefficients. Levenberg Marquardt is a least-squares/gaussian algorithm, so is somewhat noise sensitive.
Use one of the minimizer functions (e.g. Downhill Simplex) to construct your own fit using a different assumed error distribution. If you are unsure how to do this, check out a copy of Numerical Recipes in C by Press et. al. and read the section on data fitting.
Do your own data based calculation. Find the peak with Peak Detector. This will give you the magnitude, but you may want to verify it with a polynomial fit (parabola is usually good enough) across the top of the peak to avoid noise problems. Then find the positions of the half-maxima on either side of the peak. The Interpolate 1D Array will probably prove useful for this.
Choose your method depending on your pain threshold and how accurate and robust you need the result to be. Good luck!
