Performance diference for Images
Hi all,
I have a question about Images. I'm working in an applet that uses jpg images that I add as ImageIcons to some panels. I do some transformations on the original Image objects, such as cropping and scaling.
My problem is that it is extremely slower when I read the original images from filesystem files as
Image img = ImageIO.read(new BufferedInputStream(new FileInputStream(filepath)));instead of reading them from the applet context as
Image img = appletClass.getImage( url,filename);but I don't understand why! Once the image has been read into the Image object... shouldn't it be as fast working with it in both cases?
The problem is that I can't send the image files with the applet, and they must be in the local file system.
Hi, thank you for your answers!
In a first version... I used to distribute the jpg files with the .jar applet, so I could use the getImage method.
Now, each user can have different images, and I can't make different jar files for each one so I download them throught a socket to a temp file in the user's file system (is a signed applet).
I don't take care of loading times when I load the .jpg into the Image object (either using ImageIO or Applet.getImage()), because it gets loaded at the begining... and time after that, the user tries to zoom it, then I scale the read Image into a new Image object and display it in an ImageIcon.
The only difference between versions is how the Image are loaded, but I get performance differences when scaling it... (time after it's been read!).
Perhaps I'm missing something else...

Aperture, Photoshop, and Apple's possible direction for Image Editing
All,
After using Aperture now for several days, and reading many different forum topics, in particular this one which speaks of desired enhancements to Aperture:
http://discussions.apple.com/thread.jspa?threadID=253594&tstart=0
there is one thing that really sticks out on my mind. While all of us photographers have slightly different specifics to our workflow, in general they are very similar. And with respect to Aperture, there is one huge area where most of us seem to be hitting the brick wall: image adjustments, and by extension, image file management. Let me explain what I mean.
I think it is a fair generalization to say that the vast majority of serious digital photographers are using Photoshop (or some other image editing app, but I'm just going to refer to Photoshop for convenience) for post-processing of some kind. In using Aperture, and figuring out how to fit it into workflow, we've got this situation of how to move from organization and image library management to the full gamut of image adjusting functionality (photoshop) and back again to library management. The need to use photoshop then exposes the issue of how files are stored on the filesystem, etc. Stay with me here...
I have found myself thinking, and it is pretty clearly demonstrated in the forum topic mentioned above where folks are making suggestions for improvements to Aperture, that there's this barrel people are over in knowing whether Photoshop and Aperture should live in the workflow together, or whether Aperture should (or is intended to) replace Photoshop in the workflow. This got me to thinking about the fundamental question -- what is the intent, i.e. the vision for Aperture? Is it meant to replace Photoshop, or restated, is Aperture meant to be the app in which all image adjustments are to be made, OR is Aperture meant to just ease workflow, and is it intended not to be the primary app for image adjustments, but rather integrate with the primary image adjustment app?
The reason I bring this up is that the answer to this question makes all the difference in what enhancement requests and what people should expect from Aperture now, and in future versions. If Aperture is the primary place for image adjustment, then its obvious that there are some very significant additions that need to take place to Aperture, and likewise, the issue of putting images on the filesystem becomes much less important. However, if Aperture is a workflow-easer, then such image adjustment improvements are minimally important if at all, and filesystem / Photoshop / PSD file integration becomes paramount.
I know what Aperture does, what features it provides, etc. But I can't help but realize that its not really that clear (or I just don't understand yet) what the full scope of Aperture now and in the future is intended to be, and the forum topics are pretty decent documentation of the fact that the user base at this point is fairly cloudy on that too.
I can't help thinking that in the midst of the Apple pro line of tools, where we have tools that edit: video, audio, DVD creation, text effects, and now digital photography workflow, that there's one glaring hole: static image editing, i.e. a direct Photoshop competitor. I went through the Aperture video demos before Aperture shipped, and watched these photo pros talk incessantly about how "now there's an app that addresses how I work -- Aperture". That's great, but Apple has to know the role that Photoshop plays in present photography workflow -- for those pros too. So I'm sitting here thinking to myself, why would Apple roll out such a product with some clear workflow hurdles to common Photoshop usage.
Ok, here's the punchline: does anyone else here have a sneaking suspicion that Apple is not to far off from releasing their own image editing application that's a direct Photoshop competitor? I mean come on, Final Cut Pro, Motion, Sountrack, and by extension of the CEO to Pixar, Renderman. How can you not have a static image adjustment application entering the scene at some point?
I'm curious what others think. I'm just trying to make sense of how to fit the neat stuff I see in Aperture into a workflow that doesn't play very nicely with Aperture at some points (because I'm using Photoshop).

Powerbook G4-1.33GHz-17" / Powermac G4-1.4GHz Mac OS X (10.4.2) PB: 1GB RAM, Radeon 9600-64MB / PM: 1.25GB RAM, Radeon 9000Pro-128MBSo Apple adds curves adjustments,
we'll need noise reduction, greater sharpening
capability, etc., etc., and then when we have all
those features, surely we'll need masking and select
capability to perform those adjustments selectively,
etc. Where does it end?
Actually that could be a good cut-off point - add a few more/better 'global' adjustments but leave all mask, selection and layer based tasks to external editors. Personally, I used to swear by curves, but haven't really touched them in PS for a year since shooting more RAW and learning how to use the shadow/highlight adjustment properly. Sometimes for overall colour for JPEGs, but that bit can be done just as well in levels.
My workflow isn't particularly typical, but here goes.
Type of photography - stitched panoramas as a professional, plus general snapshots/nature/landscape as hobby. Single user with no network storage.
Currently I use a very organised folder structure in the Finder, along with aliases in DragThing docks for easy access to final stitched files, all with their own unique ID. RAW conversions are done in ACR/PSCS2, or Bibble if I'm in a hurry on the laptop. About 40% of the panos are shot in RAW, 40% are bracketed JPEG and the remaining 20% are 'single' JPEG. The panoramas go through quite a lot of post-processing in PS using a whole series of actions and AppleScripts.
I'm expecting my workflow to look something like this:
1) Download directly into Aperture, possibly with added help from Automator/Applescript when it comes to proper date-based names.
2) Divide download into a new album for each panorama.
2a) If it is a people pano there will be quite a lot of duplicate shots for each panohead position - make a stack for each position and choose picks - this bit will speed things up enormously by itself. Reorder stacks to fit correct order of images going around the scene.
3) Export to TIFF (sometimes JPEG) and stitch using PTMac (sometimes Realviz Stitcher). Oh, and any people who think Aperture is limited, buggy and bad value should go and look at Stitcher - it costs the same, has a far more limited feature set, is on version 5 and by comparison makes Aperture look bug-free.
4) Bring stitched panorama into Photoshop to adjust seams through layers if needed, flatten, final tone adjustments (usually using shadow/highlight), possibly some colour tweaks, sharpen. For bracketed shots I will blend together the three exposures at this point using a custom action - this kind of thing is unlikely ever to make it to Aperture.
5) Bring final print-ready file into Aperture for cataloguing/backup.
5a) If file is too big for Aperture, make a smaller version for cataloguing and store original file in Finder. This gives me a good file for 90% of purposes, with the huge file available with a bit more work.
Too big? I've found that Aperture gets sluggish with files over 18-20,000 pixels wide, and chokes totally somewhere between 25,000 and 32,000 pixels wide - 'image format unsupported'.
To summarise - organise and convert in Aperture, stitch in specialist software, do PS-specific stuff then bring final image back in to join the source images.

PDF's I'm creating with Group 4 data report Insufficient Data for Image
I am maintaining a software application, which creates PDF files from JPEG and TIFF (with Group 4 compression) image files, which typically come from scanners. It has performed well for many years, but as of the release of Adobe Reader X, we are seeing "Insufficient Data for Image" on some images.
I've read reports of this message on these forums, and I've tried shrinking the image, adjusting zoom, and upgrading to Adobe Reader XI -- none of these have worked.
Our software creates these PDF files by wrapping the raw image data in an XObject, which looks like this:
24 0 obj
<< /Type /XObject
/Subtype /Image
/Name /Im1
/Filter /CCITTFaxDecode
/Width 1704
/Height 2200
/BitsPerComponent 1
/ColorSpace /DeviceGray
/DecodeParms <</K -1 /Columns 1704 /Rows 2200 >>
/Length 25 0 R >>
stream
<<BINARY DATA>>
endstream
endobj
25 0 obj
31512
endobj
Wherein, the <<BINARY DATA>> are 31,512 bytes of raw image data -- the same data which would appear in a Group 4 compressed TIFF file.
Indeed, when we do create a Group 4 TIFF file with the same binary data, it opens successfully in all common viewers.
Any assistance, such as the precise meaning of this error message, could be helpful.Just a note that the bug appears to relate to JPXDecode, so far as all previous reports seem to suggest (no inside information). JPXDecode supports multiple image resolutions in the same image, so messing with zoom sometimes helps. If you can post a complete file somewhere it might interest someone who could analyse it.
The message simply means that decompressing the filters does not yield enough bytes. This may either reflect that there really isn't enough data, or it could indicate any kind of data error (which causes the filter to silently return EOF). -
Sometimes Undo is "Undo Save History State for Image"...
Anyone know why the Undo command occasionally produces "Undo Save History State for Image" rather than a proper undo of the last operation?
I am aware of your contribution to this forum and genuinely have utmost respect for what you say, however without getting too heavily into the semantics of the meaning of the word “bug” I would truly appreciate your thought on this …
b_gossweiler wrote:
If you export (or also print) an image, an entry is inserted into the develop history of the image. Although these steps (export, print, ...) cannot be physically undone, the undo removes this history step from the develop history of the image. This makes sense and - IMHO - is not a bug at all.
Beat
Would it not be reasonable that when a user requests an “undo” that they would expect this to undo the last thing “they” did regardless of what any background task is doing?
If this does occur when performing some background task on several hundred or thousand images does this mean that they could struggle to actually achieve any meaningful undo operation on what they are currently working on because they could be attempting to undo many state changes? If so, could one consider that from a user’s perspective the undo mechanism is actually broken in this scenario?
If they request an “undo” and it does not perform to the users reasonably expected behaviour would it not reasonably be considered at least undesirable if not a bug?
If they perform an “undo” and they get this message have they actually undone something which might be important?
Even if it has no ill effects the message alone could be unsettling and confusing to users?
You say it makes sense and I know I’m slow, but I would not expect a user to see this message when the user wants to undo for example the modification to exposure or other slider they have just changed.
I’m not hung up on this as I have seen no ill effects other than mild inconvenience; however I would respectively appreciate your views on how this “makes sense” from a user’s perspective. -
Looking for Image Button Applet
I'm looking for a simple image button applet (normal state, mouse-over and mouse-click) which can refer to a HTML or start a Javascript function. Can anyone help?
KippieHi,
This is the source code. I don't quite understand what I should do with the tokens. I hope this is allright. Thanks for your help

Program Name: ImageURLButtonBar
Author: Paul Whitelock
Version: 1.1
Copyright: (c) 1997 by Paul Whitelock and Modern Minds, Inc.
Requires: ImageURLButtonBar.class
ButtonBar.class
ButtonBarObserver.class (Interface definition)
ButtonRegion.class
ButtonAnimate.class
Modifications: v1.01 (15 April 97)
* Added "sticky" button behavior (controlled
by applet "stick" parameter)
v1.03 (25 June 97)
* Added applet parameter "useCodeBase". If useCodeBase
is true, then image file locations will be based on the directory
in which the Java class files are located. If useCodeBase is false, then
the locations will be based on the HTML directory. Note that audio
file locations are always based on the Java directory. The default
for useCodeBase is false (use HTML directory for base).
* The "stick" parameter will now accept a button number in
addition to the value of "true" or "false". If a button number
is specified, then that button will be "stuck" down
when the button bar initializes.
* Added the capability of loading multiple URLs for each button
with an optional target for each URL.
v1.1 (25 September 97)
* Added "baseBrighten" and "baseBrightenTint" parameters to control
highlighting for base button bar.
* Added "mouseOverBrighten" and "moBrightenTint" parameters to control
highlighting for base button bar.
* Added "mdBrightenTint" and "mdBrightenAll" parameters to control
highlighting for base button bar. Previous versions of the applet
supported "mouseDownBrighten," but only if button borders were not
drawn for the button-down button bar (the "mdBrightenAll" can be set
to "true" to override the this default behavior).
* An "appletBGColor" parameter has been added to set the
applet background color. The applet background color is
sometimes visible during scrolling or during a page repaint.
NOTE: This source code was composed using Microsoft Visual J++
with tab stops of 4. Text may not be formatted correctly
if another editor is used.

Performance Issue for BI system
Hello,
We are facing performance issues for BI System. Its a preproductive system and its performance is degrading badly everyday. I was checking system came to know program buffer hit ratio is increaasing everyday due to high Swaps. So asked to change the parameter abap/buffersize which was 300Mb to 500Mb. But still no major improvement is found in the system.
There is 16GB Ram available and Server is HP-UX and with Netweaver2004s with Oracle 10.2.0.4.0 installed in it.
The Main problem is while running a report or creating a query is taking way too long time.
Kindly help me.Hello SIva,
Thanks for your reply but i have checked ST02 and ST03 and also SM50 and its normal
we are having 9 dialog processes, 3 Background , 2 Update and 1 spool.
No one is using the system currently but in ST02 i can see the swaps are in red.

Relative paths for images upset by forwarding requests
Hello World.
I am using a web app deployed in Weblogic 5.1 with service pack 8.
I have hit a problem which puzzles me. When I forward a request from
one JSP to another (say from A to B) the web server seems to take the
URLs of the images on the served file (B) relative to the path on the
calling file (A). Here's a detailed explanation...
Suppose I have a the web app structured as follow
/oddApp/launch/A.jsp
/oddApp/B.jsp
/oddApp/images/tick.gif
Page A simply stores its request URI and forwards its request to page B
<jsp:forward page="/B.jsp" />
Page B displays its requestURI, contextPath and servletPath. It also
attempts
to show three images
<img src="images/tick.gif">
<img src="../images/tick.gif">
<img src="/images/tick.gif">
When I invoke page B directly, the first image is shown, the others are not.
When I invoke page A, it forwards to B and the second image is shown, the
others are not.
In each case the URI, contextPath and servletPath are correctly displayed
with regard to page B.
URI = [oddApp/B.jsp]
contextPath = [oddApp]
servletPath = [B.jsp]
The URI in A.jsp is also correct (i.e. /oddApp/launch/A.jsp).
The search for the images seems to be relative to the original URI (i.e. not
the URI used to forward), which strikes me as daft. It means that page B
must be aware of where it is being called from. It is perfectly plausible
that
relative paths which suit when called from one location are incorrect when
called from another.
I had thought that including the leadling slash (as shown as the third
image)
would cause the search relative to the document root (/oddApp/), but this
appears not to be the case. The search is done relative to the root of the
server not the web app.
Adding jsp mappings in the deployment descriptor of the web app does not
help (I had thought it a long shot anyway).
Does anyone have any thoughts on this?
PHiL
i face the same problem (WinNT, WLS6.0): my wep app has a contextRoot " root " which makes it react to the URL: http://host:port/root /: it is this folder which will be used as a basis by the Web server But in the jps I use a relative URL for images: / images/toto.gif : it works very well when I deploy my jsp out of a Web-app by setting a document.root to the weblogic web server.On the other hand, once deployed in a Web-app, images are not found because the default path of the browser is http://host:port, without the context root of the Web-app! In other words, my war has images/*.gif in its root but when /images/toto.gif is resolved in a jsp, as the relative URL is not prefixed by my context-root, the image is not search in the war! actually, if I type http://host:port/root/toto.gif, my image appearsany clues? an alias on the web server? a setting in web.xml/application.xml and their weblogic equivalent files?

How do I show file size in the Finder icon view for images?
How can I add the file size to the icon view "File Info" for images?
I know how to get it to display the image size under View Options. In this mode it shows pixel dimensions for some images (not for svg or pdfs tho) and file size for some non-images (rar, zip, but not txt or plain text files).
Is there some plist I can modify?Just found the answer in a post with this subject:

DrawImage takes long time for images created with Photoshop
Hello,
I created a simple program to resize images using the drawImage method and it works very well for images except images which have either been created or modified with Photoshop 8.
The main block of my code is
public static BufferedImage scale( BufferedImage image,
int targetWidth, int targetHeight) {
int type = (image.getTransparency() == Transparency.OPAQUE) ?
BufferedImage.TYPE_INT_RGB :
BufferedImage.TYPE_INT_RGB;
BufferedImage ret = (BufferedImage) image;
BufferedImage temp = new BufferedImage(targetWidth, targetHeight, type);
Graphics2D g2 = temp.createGraphics();
g2.setRenderingHint
RenderingHints.KEY_INTERPOLATION,
RenderingHints.VALUE_INTERPOLATION_BICUBIC
g2.drawImage(ret, 0, 0, targetWidth, targetHeight, null);
g2.dispose();
ret = temp;
return ret;
}The program is a little longer, but this is the gist of it.
When I run a jpg through this program (without Photoshop modifications) , I get the following trace results (when I trace each line of the code) telling me how long each step took in milliseconds:
Temp BufferedImage: 16
createGraphics: 78
drawimage: 31
dispose: 0
However, the same image saved in Photoshop (no modifications except saving in Photohop ) gave me the following results:
Temp BufferedImage: 16
createGraphics: 78
drawimage: 27250
dispose: 0
The difference is shocking. It took the drawImage process 27 seconds to resize the file in comparison to 0.78 seconds!
My questions:
1. Why does it take so much longer for the drawImage to process the file when the file is saved in Photoshop?
2. Are there any code improvements which will speed up the image drawing?
Thanks for your help,
-RogierYou saved the file in PNG format. The default PNGImagReader in core java has a habit of occasionally returning TYPE_CUSTOM buffered images. Photoshop 8 probably saves the png file in such a way that TYPE_CUSTOM pops up more.
And when you draw a TYPE_CUSTOM buffered image onto a graphics context it almost always takes an unbearably long time.
So a quick fix would be to load the file with the Toolkit instead, and then scale that image.
Image img = Toolkit.getDefaultToolkit().createImage(/*the file*/);
new ImageIcon(img);
//send off image to be scaled A more elaborate fix involves specifying your own type of BufferedImage you want the PNGImageReader to use
ImageInputStream in = ImageIO.createImageInputStream(/*file*/);
ImageReader reader = ImageIO.getImageReaders(in).next();
reader.setInput(in,true,true);
ImageTypeSpecifier sourceImageType = reader.getImageTypes(0).next();
ImageReadParam readParam = reader.getDefaultReadParam();
//to implement
configureReadParam(sourceImageType, readParam);
BufferedImage img = reader.read(0,readParam);
//clean up
reader.dispose();
in.close(); The thing that needs to be implemented is the method I called configureReadParam. In this method you would check the color space, color model, and BufferedImage type of the supplied ImageTypeSpecifier and set a new ImageTypeSpecifier if need be. The method would essentially boil down to a series of if statements
1) If the image type specifier already uses a non-custom BufferedImage, then all is well and we don't need to do anything to the readParam
2) If the ColorSpace is gray then we create a new ImageTypeSpecifier based on a TYPE_BYTE_GRAY BufferedImage.
3) If the ColorSpace is gray, but the color model includes alpha, then we need to do the above and also call seSourceBands on the readParam to discard the alpha channel.
3) If the ColorSpace is RGB and the color model includes alpha, then we create a new ImageTypeSpecifier based on an ARGB BufferedImage.
4) If the ColorSpace if RGB and the color model doesn't include alpha, then we create a new ImageTypeSpecifier based on TYPE_3BYTE_BGR
5) If the ColorSpace is not Gray or RGB, then we do nothing to the readParam and ColorConvertOp the resulting image to an RGB image.
If this looks absolutely daunting to you, then go with the Toolkit approach mentioned first. -

Edited by: kishan P on Sep 17, 2010 4:50 PMHi Peter,
I would suggest few changes in your code. Please refer below procedure to optimize the code.
Steps:
Please run SE30 run time analysis and find out if ABAP code or Database fetch is taking time.
Please run extended program check or code inspector to remove any errors and warnings.
Few code changes that i would suggest in your code
For select query from t001w & marc remove the corresponding clause as this also reduces the performance. ( For this you can define an Internal table with only the required fields in the order they are specified in the table and execute a select query to fetch these fields)
Also put an initial check if str_table[] is not initial before you execute the loop.
where ever you have used read table. Please sort these tables and use binary search.
Please clear the work areas after every append statment.
As i dont have a sap system handy. i would also check if my importing parameters for the bapi structure is a table. Incase its a table i would directly pass all the records to this table and then pass it to the bapi. Rather than looping every records and updating it.
Hope this helps to resolve your problem.
Have a nice day
Thanks -
Error opening PDF in 9.1.0 ("Insufficient Data for image") and 7.0.9
I generate PDF documents in code (basically converts TIFF images to PDF, using FOP).
Few of the PDFs can not be viewed on Adobe Reader 9.1.0, and 7.0.9. But, these open fine on 8.0 version.
With 9.1.0 version I get error as "Insufficient Data for image"
With 7.0.9 the error is "A drawing error occured"
8.0 works fine and opens the PDF.
Is there any issue with 9.1.0 for opening PDFs, I got this version installed recently on my system.
Appreciate an early help/views on this issue.
Thanks,

It worked for me and (as it seems) solved a one year long anoying issue.
1. Exit Acrobat.
2. Choose Start > Run, and type: %APPDATA%\Adobe\Acrobat\ into the Open text box. Click OK.
3. Right-click either the 6.0 or 7.0 folder, and choose Delete.
I deleted both folders.
Dont worry these two preferences folders will automatically be renewed by acrobat! -
Radio group with URL for image in a table
I'm trying to display some text and an image for a radio group so the form looks like

( ) text for item 3 {image for item 3}

Re: Is it possible to display an image instead of button in a radio group?
How to show image in radio group ?
It looks like all I have to do is create a LOV that looks like:
SELECT {complex stuff that generates the text string, img tag, and URL for image}
,DB_PK
FROM dynamic_view_for_lov -- public synonym
But, my images are stored in a table.
I have been able to create an IR using the "Column Format=BLOB" method.
The SQL for the report looks like:
select
db_pk, display_text, image_len, image_clob
from dynamic_view_for_lov -- public synonym
And the Number/Date Format for the IMAGE_LEN column is:
IMAGE:DYNAMIC_VIEW_FOR_LOV:IMAGE_BLOB:DB_PK::::::Inline:Download
My question: How do I create the URL for the img tag for the LOV?
many thanks

I think Homer Simpson said it best: Doh!
For the person in the future, you have to 'fake create' the Automated Row Fetch process.
The get_blob_file_src gets all the information from that Process and the column name of the Item Type that is on the same page.
I forgot where I read about that trick.
Basically, you create the Automated Row Fetch process, then 'disable' it.
Same thing with the required Item Type. Create it as a "File Type", just to tell APEX that it comes from a Database Column,.... then change it to a 'hidden' type.
You don't have to "fake' it if the application already contains the file upload item and ARF. The assumption is that the application will contain these components in order to maintain the BLOBs and you'll just reference the functional ones. -
Regarding performance widget (performance objects) for custom dashboard
Hi,
I'm making a custom dashboard, I'm trying to use the performance widget for a netapp volume, but the performance objects are not available and only see "(All)" on the options (see screenshot). When I create the dashboard it shows the widget
with empty information.
Thanks for any suggestions.Hi all,
I managed to fix all my dashboards, from what I understand it is not a supported MS fix as per articles I found on forums etc.
My issues started when I renamed some of my groups because of requirements, think SCOM 2012 doesn't like the rename, serious bug that I think causes the info in the db's to go out of sync etc.
Also found that data from the main opsmgr db to the dwdb hadn't submitted for months, so my reporting was way out. Hence blank stats on dashboards and uptime reports showed grey.
I followed this article and fixed it, please ensure that your db's are fully backed up before doing this. OperationsMananger DB and the OperationsManagerDW db.
The issue in the end is actually with the DW db.
