Problem with showing some JPG files in Delphi

Question

i have tried to open some JPEG files in Delphi with TImage component. i also added the Jpeg unit. i can open most of jpg files and there is no problem.

but when i try to open some JPGs, the program just throw an exception.

i also tried to load that images in design mode, but there is some problem. in design mode the exception is:

Access violation at address 402672A1 in module 'vcljpeg70.bpl'. Write of address 08E84000

Why i cannot open that JPGs? they are not corrupted. i checked them in some tools like savantools EXIF viewer.

here is the URL of one of that images: http://xs842.xs.to/xs842/09340/backpic435.jpg

Thanks so much

PS: My Delphi version is 7. Borland Delphi 7

Answer 1

The reason you may be encountering this problem is due to the file type. Delphi has issues displaying JPEG images that have been encoded using CMYK, rather than the default RGB encoding. CMYK is a format that is generally used for Print design, try and always encode your images to RGB format to avoid this issue with Delphi.

Patch for Delphi jpeg.dcu

Bye.
