Adding gif/jpeg image to frame
Hi,
Can anyone please tell me how to add a jpeg/gif image or an icon to the title bar ofa frame such that it appears before the title.
Thanks
Image myImg=Toolkit.getDefaultToolkit().getImage(
getClass().getResource("YourImage.gif"));
myFrame.setIconImage(myImg);~Bill

GIF/JPEG Images Always Open As "Locked"
Hey,
When I open up my images of JPEG/GIFs as "Locked". PNG image types are fine and aren't locked on opening but I really don't know why my JPEG and GIF's are always locked.
I can fix it by just duplicating it on the JPEG files, allowing me to make changes to my image but on GIFs it wont even let me duplicate.
Anyone know what is going wrong?
HattonI think what your seeing is normal for file formats that don't support layers.
For jpegs, just double clicking on the background layer thumbnail in the
layers panel and clicking ok in dialog that appears should unlock the layer.
Instead of doing that, i usually drag the background layer to the new layer icon
at the bottom of the layers panel. This creates a background copy that you
can work on and should be unlocked.
Your gifs are probably in the Index color mode (says Index beside the layer thumbnail)
To unlock gifs go to Image>Mode>RGB.

Howto remove gif, jpeg (images) from e-mails?
Hi Gurus.
Please help, I want to remove gifs and other images from emails and deliver the rest of content to the user mailbox.
Many thanks
BRHi,
Look at the conversion channel in the Messaging Server Administration Guide. This allows you to replace the MIME contents of messages e.g. replace/remove a gif or other images that you specify.

Inserting gif/jpeg image into excel through POI-HSSF
HI,
I am using jExcel to generate xls file from java. But I have to include image into the excel sheet. but jExcel supports only PNG file format to insert into excel sheet.
what about POI-HSSF? Does it support inserting images into Excel or not. if supports what type of images it will support?
I am in urgent need of it. Help me out in this issue

You did not mention which version of POI. Did you verify your
version supports the patriarch.createPicture method? If you are
using a really old version it might not.
> loadPicture("asset/images/logo_e2eA.png",
workSheet))/>
Does the code actually have access to a loadPicture() method
or function? I think loadPicture() is a private method in one of
the example classes: org.apache.poi.hssf.usermodel.examples.*. So
you may have to write your own version of it. Assuming you have not
done so already... -

How to save applet in image(gif/jpeg) format
Hi there !
how to save applet in image (gif/jpeg) format. i have just gone through JIMI package where serilization is there ,WHERE U CAN SORE in image format ...........can anybudy help me out.........if possible then pleeez provide me some example.
Thanks in advan...........I think that is possible because i have seen some commercial applets that do that.
-http://www.izhuk.com/painter/
-http://www.lawrencegoetz.com/programs/signature/
Thses two saves the image in the server since applets cant write in the host they are running. Maybe it would be possible whit JFS, i don't know.
For now I am trying to store an image draw in the applet on my server.
My idea now is copying the image to a buffer or something, open a connection to the server and receive the image with a perl CGI.
There is an example with text:

How combine a jpeg image & animated gif image & save it as GIF ?
i have an jpeg image, & also aminated gif image, how do i place the animated gif image over (in the center of the image) a jpeg image & save it as gif file ??
First thing you need to do is stop thinking in terms of file formats once the files are in photoshop they are all the same. The exception being vector vs raster. But in this instance the process is rteally the same so 6 on one hand a half a dozen on the other. Or as some would say Tomatoe, tomahtoe(mispelled on purpose).
The jpeg I would assume is the background image and the gif image is the fore ground object. Open the jpeg, and then place the gif file. As long as the fore ground object has transparency, your job is pretty much done. If not, then it will be up to you to mask what you want to keep vs what you don't and apply that selection to the foregrounds layer as a mask.
Google the net or skim the users manual for the keywords - mask, selections, quickmask, pen tool, paths. Each of these can in one way or another take care of your issue.
It would be worth your time to also go through the numerous videos about photoshop and see how its done.
Either go to adobe tv,
Itunes podcasts
or one of the following web sites:

Captivate Adding JPEG images! HELP!
Good day all,
I am having an issue with Captivate, that I've never had
before. I've used Captivate now to develop interactive simulations
on three other projects, so I'm familiar with Captivate itself.
However, just recently I started developing more simulations for a
interactive tool that we use here at work. But on every simulation
that I have recorded so far, Captivate seems to be inserting1-5
JPEG images on the first slide. I can't delete these, and when I
do, it completly freezes Captivate. These images have slowed down
Captivate so much. I can't even access the "edit" tab. i have to
double click another slide, and then it finally takes me to the
edit tab. Does anybody have any idea as to the problem?? I can
probably get a screen shot of these so called images in the time
area in Captivate itself.
Hoping somebody can help me out!You didn't say what version you are running - that might be
important. You did say:
quote:
But on every simulation that I have recorded so far, Captivate
seems to be inserting1-5 JPEG images on the first slide. I can't
delete these, and when I do, it completly freezes Captivate
Let me restate the issue in beta-style steps, to see
if I have it "right", okay?
1) You are recording in one of the simulation modes ...
2) After pressing the END key to stop recording, you are
returned to Captivate where ...
3) Your new recording is waiting in storyboard view...
4) You cannot access slide #1 in Edit view, so you open any
other slide ...
5) And work your way back to slide #1 from there ...
6) To find that on slide #1 timeline, there are from 1 to 5
JPEG images ...
. . . .(that have nothing to do with the application you
recorded?) . . . .
7) And apparently not just any JPEG images but images
so large they actually burn all resources on your computer,
causing Captivate to freeze.
Please let me know if I'm restating your problem correctly
(above). I am nearly positive that I have
not understood you. But if that's the case, perhaps you
could restate the problem in the "step" format I've used here, so
that we can understand and try to resolve the issue. Thanks very
much!

Problem displaying CMYK jpeg images
I have a problem with a CMYK jpeg image.
I know that about supported JPEGs in JRE - JCS_CMYK and JCS_YCCK are not supported directly.
And I found here how to load the image:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4799903
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5100094
I used both the suggestions described to load it, but when the image is displayed the colors are wrong, are very different from the one displayed in PhotoShop, for example.
Any suggestion are very appreciated. If it's necessary i can send you the image.

}The loading process It takes about 10 seconds, and every repaint it takes the same time.The painting yes, the loading no. It shouldn't take much more time to load the image then an ordinary JPEG. In particular, your now using a "natively accelerated" JPEG image reader, so it should take less time on average to load any JPEG. 10 seconds is absurd. Are you sure your not including the drawing time in that figure?
- Another problem: JAI-ImageIO is not available for MAC OS X platform.This is somewhat true. You can take the imageio.jar file and package it together with your program (adding it to the class path). This will give you most of the functionality of JAI-ImageIO; in particular the TIFFImageReader. You just won't be able to use the two natively accelerated ImageReaders that comes with installing.
Right now, you're using the accelerated CLibJPEGImageReader to read the image. You can't use this image reader on the MAC, so you have to take the approach mentioned in the 2nd bug report you originally posted (i.e. use an arbitrary CMYK profile).
The conversion is too long more than 30 seconds.The code you posted could be simplified to
BufferedImage rgbImage = new BufferedImage(w,h,
BufferedImage.3_BYTE_BGR);
ColorConvertOp op = new ColorConvertOp(null);
op.filter(cmykImage,rgbImage);But again, 30 seconds is an absurd value. After a little preparation, converting from one ICC_Profile to another is essentially a look up operation. What does,
System.out.println(cmykImage.getColorModel().getColorSpace());print out? If it's not an instance of ICC_ColorSpace, then I can understand the 30 seconds. If it is, then something is dreadfully wrong.
the RGB bufferedImage that i get after the transformation when it is displayed is much more brightThis is the "one last problem that pops up" that I hinted at. It's because some gamma correction is going on in the background. I have a solution, but it's programming to the implementation of the ColorConvertOp class and not the API. So I'm not sure about its portability between java versions or OS's.

Using QuickTime Pro to convert a series of JPEG images into a QT movie?
Can I use QuickTime Pro to convert a series of JPEG images into a QT (uncompressed) movie? Thanks...
Windows XPYes.
One of the features of the QuickTime Pro upgrade is "Open Image Sequence". It imports your sequencially named (1.jpg, 2.jpg) liked sized images (any format that QT understands) and allows you to set a frame rate.
http://www.apple.com/quicktime/tutorials/slideshow.html
You can also adjust the frame rate by adding your image .mov file to any audio clip. Simply "copy" (Command-A to select all and then Command-C to copy) and switch to your audio track.
Select all and "Add to Selection & Scale". Open the Movie Properties window and "Extract" your new (longer or shorter) file and Save As.
As you've posted in the Mac Discussion pages but your profile says XP you'll need to subsitute Control key where I reference Command key. -
How do i create a jpeg image from clips in fcp
how do i/can I create a jpeg image from clips in fcp?
StephenSelect clip in timeline and place the playhead over the frame you want to save as a JPEG. Open the share window ( Button on far right of tool bar) and select 'Save current frame'. If you don't see that option click on add destination and select the Save current frame choice. It will be added to your share options.

ID ePUB export converts all *inline* anchored JPEG images to PNG?
During ePUB export, when Image Conversion = Automatic, anchored JPEG images with Position = Inline are converted to PNG. If Anchored Object Position = Custom, the same images stay JPEG. Anyone know a better way to avoid than the less-than-ideal options below?
Less than idea options:
a) Use Image Conversion = JPEG (would also convert existing .gif and .png images)
b) Specify Object Export Options for each image frame that contains a JPEG.
Maybe this is just a bug.Here's the definition from the InDesign Help file:
Image Conversion
Lets you choose whether the optimized images in your document are converted to GIF, JPEG, or PNG. Choose Automatic to let InDesign decide which format to use in each instance. Choosing PNG disables the image compression settings; use PNG for lossless images or for images that include transparency.
Choosing Automatic means InDesign decides which format to use. It doesn't mean keep the same format. -
Sorry if this is in the wrong forum.
I am extracting JPEG images stored in a blob field in a DB. I can obtain the bytes of the JPEG in a couple different ways but I have had no luck in scaling the images.
I need to simple scale the image, and then return the new image preferably in a byte[] or something that I can convert to a byte[].
I have come accross several past post, and at times seems to work. None of them actually return an image or errors so I am not sure where it fails.
I tried a modified version of the following which was an example on making thumbnails out of a larger image.
Here's the url to that example
http://developer.java.sun.com/developer/TechTips/1999/tt1021.html
After modifying the code, when I went to test I recieved a weird error in a log file that basically said something could not use :0 which is refering to my monitor.
This is and will be used in a Linux env, but does not or should not invlove X in anyway. I have come accross other example that talk about a frame.addnotify() method that is supposed to resolve this issue when not outputing to a monitor.
After adding that, the error is not there, but neither is my scaled image.(which wasn't there before either)
If this sound strange, that's beacuse I am creating a custom Generator object. Generator being a Servlet created by Macromedia to generate Flash movies and etc. on the fly.
For some reason in the API it lacks the ability to scale a JPEG image. Yet to be able to put the image into Flash, I must get the image's byte[].
Please help, I have played around with this one for some time now, and have tried more things than I could document here.
Any assistance is greatly appreciated!
