How to define the size of saving image in sm or inch?

Hi,
is it possible to get the image of size defined in sm or inch?
There is no stable proportion between width in pixel and sm.
My purpose is to create a buffered image of defined size ( for example 5x5 sm) and save it. The saving is made with encoder in jpeg.
Thanks and Regards,

...didn't find sm in the International System of Units (second � meter ..?)

How to decrease the size of an image (CS5)?

I need help with how to reduce the size of an image to fit various smaller sizes. E.g. 135 x 380mm, 254 x254mm etc mounted/matted. Therefore, the image must be made smaller than these sizes without losing quality and any part of the image. I am unable to crop to achieve these sizes since I need the full image. These photos were taken by using a Canon D450 camera and in both RAW & JPEG.
Your help is much appreciated.

You may want to use Image > Image size... and dial in the sizes you want.
Set your units to mm in the dialog. Turn off resample and you can adjust the final print size.
What I am showing you is called "scaling", changing the print size without throwing out pixels as resample would do. Your image is intact. This is from CS6, but it should be about the same in CS5.

hi,
I have a database which contain an image. now i
want to retrieve this image & want to show this
image in my jsp page as user's defined size. I have

size of an image. Now i want to see different size
of this image. How is this possible? I know control
the size of this image after saving this image
n a file. but i want to control the size of this
image without saving this image in a file? IS it
possible ? Is there anybody can help me?This has nothing to do with JDBC; you can only store and retrieve the image you have and there's no image manipulation functions in JDBC (nor should there be).
I can see 2 options:
1) serve the image file as is, but in the jsp that writes the html that contains the "<img>" tag that gets it, use the "height" and/or the "width" to scale the suppied image to presentation size you want.
2) find some image manipulation code that will convert the image into the size you want
Option 1 will work well if the problem you have is merely refining the image size for presentation. Option 2 is your only coice if it's the image files size itself you really want to change, not just it's appearance on a page.

How to control the size of SVG images in epub files?

There is unfortunately no support for SVG files in InDesign.
Most of my images in jpg convertes nicely, but the small ones do not.
Therefore I want to use SVG files which I have created in Illustrator.
But how do I set the size in the epub file? Right now, whatever I do, they come out too big and I don't know how to control the size.
Is there a program, like Sigil or other, that can place the image for me - I'm no html wizard you see....

In any Java program, it is good practice to make sure your live objects leave some room in the heap for "scratch space." Without this, you will spend too much time in GC, and, in the worst cases, run out of memory. In the general case, you can see how much live data your application requires by looking at the heap used after a full GC's. For Coherence, you should ensure that live data, as you say, is under 70% of the maximum heap size.
Coherence provides you tools to help enforce this policy. [http://coherence.oracle.com/display/COH35UG/local-scheme] describes how to size limit your cache. By implementing an eviction policy, you can control what happens when a size limit is exceeded.

How to define the query condition of Image Theme in MapBuilder?

Hi,
I'm trying to add an dynamic Image Theme in OracleMap, but there's a problem.I defined the query condition of Image Theme like this:
select scanimage,shap from image where scanimgid=467
The shap column is the MBR column
And the XML CODE:
<?xml version="1.0" standalone="yes"?>
<styling_rules theme_type="image" image_column="SCANIMAGE" image_format="JPEG" image_unit="M" image_resolution="1.0">
<rule>
<features> select scanimage,shap from image where scanimgid=467 </features>
</rule>
</styling_rules>
When i preview this Image Theme ,there is an ORA-00936 error means lack of expression.
Is there any problem with my definition?Or can query an image from an Image Theme?
Thanks a lot for your help!

Hi Mars,
predefined image theme definition does not support a "select" statement in the <features> tag. You should just define a query condition in the <features> tag.
It seems that you are trying to use an image theme in Oracle Maps, but it currently does not support a FOI image theme. You should add a predefined image theme as part of the basemap, and maybe add scales values to set the visibility range of this image theme.

How to decrease the size of an Image in iAD

Hello, there!
I am trying to producer a new slide where I can write text in iAD.
I have problems with it though and can you please tell me how to add new slides, where I can either write text or add new objects or assets?
Also when I try to use the CAROUSEL, I can only put it there, but once I put the asset image on it, it doesnt work - I can't place the image in the center of each boxe and it doesn't go full screen once I click on on it through my iPod Touch (5th Generation).
Please answer me those questions and I would be very happy indeed

How to detect the size of an image

Hi,
I have a servlet which grabs an image (jpg or gif) from a BLOB stored in my database and sents the image back to the client through the ServletOutputStream. This all works good and the image is presented nicely. However, I now want to have my servlet detect the size of the image, and if it is too big resize the image and return it.
As I am new to images in JAVA I am unsure how to do this and what tools to use for it. I found some information on JAI, but this seems way to elaborate for what I need. Please let me know if anyone knows how to do this.
Thank you and regards,
Joost Schouten

How to define the size of report area and its elements?

How can I define the report area size and its elements? And how can I define that for each printed paper, the details area will repeat horizontally or vertically?
Is there any way to change the measuring units?
Are there any difference between Crystal Reports that is bundled with Visual Studio 2005 to the standalone version that don't allow me doing what I need?
Thanks.

Hi Juliano,
I hope this is what you had in mind...
1. File / Page setup: set your paper size, portrait/landscape and margins.
2. Section Expert: the page header &footer sections are 'locked' in that each page will have the space indicated dedicated to these sections; report header & footer - this is the space dedicated on the first and last page of the document. The remaining space available will be used up by the Details section.
I'm not sure how you can get the Details to print verticall vs horizontally - except maybe with cross-tab format.
3. Measuring units: is this for the ruler? This is pulled from your computer settings.
The rest I'm not sure about but I hope this is enough to get you started!

How to define the size of a EVS as 0(null)

Hi,
Actually in my project I have done 3 fields
1.firstdate
2.Lastdate
3.Absence Type(EVS which hold the data from BAPI)..
When I select firstdate and lastdate it is calculating and it is showing the no of days by clicking of a action..and when selction of some conditoin(like some sickleave it should show medical check box otherwise not)...
Everything is working fine..
1.selcting of date (FD and LD)and selecting of that EVS(Sickleave)it is coming the output..
2.selcting of date (FD and LD)and selecting of that EVS(other kind of leave )it is coming the output
but my problem is that without selcting the EVS field when i select(FD and LS)it is showing null pointer Exception..here I have to select the EVS Feild..but it should not be like this....all are indepent ..so here I have to check the size of a EVS Field. as null...but it is not supporting in NWDS..Is there other way..
public void onActionfullday(I created one action)(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
 //@@begin onActionfullday(ServerEvent)
wdThis.wdGetCustContLeaveReqController().Bapi1(wdContext.currentContextElement().getAbsent_From(),wdContext.currentContextElement().getAbsent_To(),"CH","CH");
 if(wdContext.nodeBapi_Working_Days().size()>0 ){
 wdContext.nodeBapi_Working_Days().moveFirst();
 wdContext.currentContextElement().setAbsdays(wdContext.currentBapi_Working_DaysElement().getWorking_Days());
if(wdContext.currentContextElement().getAbs_Type().equals("Accident")||wdContext.currentContextElement().getAbs_Type().equals("Accident 25 %")||wdContext.currentContextElement().getAbs_Type().equals("Accident 50 %")||wdContext.currentContextElement().getAbs_Type().equals("Sickness 25 %")||wdContext.currentContextElement().getAbs_Type().equals("Sickness 50 %"))
 wdContext.currentContextElement().setMedical_visible(WDVisibility.VISIBLE);
 else
 wdContext.currentContextElement().setMedical_visible(WDVisibility.NONE);
without selecting absence type and selecting of the FD and LD i should get the result boz these two fields are not dependent of each other.......

Hi Suman,
 if your problem is to avoid null pointer exception for EVS, before executing RFC you can check (wdContext.node<EVS>.current<EVS>element!=null). then you can populate a message for warning the user to enter EVS field.
and stop executing RFC.
thanks

actually your doing it right
netdownwidget.width = 100
in awesome-git the syntax is different. i would recommend using the non-git-version, because the most tutorials are for older versions.
without reading the references of the git version, try something like netdownwidget:set_width(x)
// edit: your icons arnt centered, maybe ur interested in that command:
for x in *.xbm; do convert -fill "#afa72e" -transparent white -colorize 100 -bordercolor transparent -border 8x8 -gravity center -crop 16x16+0+0 "${x}" "${x%.*}.png"; done

How to get the size of an image?

yhanks

try something like:
// in case 'this' is a JComponent or something similar:
MediaTracker mt = new MediaTracker(this);
mt.addImage(myImg1, 1);
mt.addImage(myImg2, 2);
while (!(mt.checkAll(true))) {
try {
Thread.sleep(10);
} catch (InterruptedException iex) { }
// all loadedThis would load all images registered with the MediaTracker but also blocks execution of your program. You might want to start a different thread for this.
cheers,

How to define the size of each column of a GridLayout in HTMLB?

Hi there,
I think everything is in the subject. It seems it is not possible. The GridLayout.setWidth() refers to the grid in general and it is not possible to select a GridLayout column (in order to apply to it a setWidth()).
When I do a GridLayoutCell.setWidth() I can't see any change as well.
Maybe the only possibility is to nest several GridLayout?
Does someone have a clue on this?
Thanks in advance
Renaud

Here is my code:
GridLayout gl = new GridLayout();
gl.setCellSpacing(10);
gl.setWidth("50%");
Here it's inside a loop:
GridLayoutCell imageCell = new GridLayoutCell(sapLogo);
imageCell.setWidth("20%");
gl.addCell(++cellrow, 1, imageCell);
GridLayoutCell linkCell = new GridLayoutCell(link);
linkCell.setWidth("40%");
gl.addCell(cellrow, 2, linkCell);
GridLayoutCell radioButtonCell = new GridLayoutCell(radioButtonGroupGUI);
radioButtonCell.setWidth("40%");
gl.addCell(cellrow, 3, radioButtonCell);
I tried to change the percentage values but it never works how I want. I need the first column to be very thin.
