Oh ok that helps and it seems that it does something. I found the code
examples that you meantioned. Thanks. Now I am encoding and sending it
to a filestream which I do by:
err = pnoJpeg2EncodeCreate(pnoJpegRefNum, &jpegEncode);
pnoJpeg2EncodeToFileStream(pnoJpegRefNum, jpegEncode, neoslateJPG);
....
setting up the image as in the code example from the documentation
....
err = pnoJpeg2Write(pnoJpegRefNum, jpegEncode, helperBitmap);
then free and close the library
I get my bitmap from WinGetBitmap(WinGetDisplayWindow());
When I do all this everytime regardless of what I am trying to encode
it ends up being a 4kb image which seems to be corrupt or incomplete.
Is this because of high density screens or is there a special way to
be grabbing my bitmap?
I've tried creating a offscreen bitmap and using the BmpCreateBitmapV3
to create my bitmap. Then copying from the current screen to the
offscreen one but the image still seem to be 4kb.
Any ideas or has anyone seen something like this before.
Again thanks as always for your help,
Landon Cunningham
