With latest DevExpress VCL update the standard ImageList can't load bmp images. Selecting a bmp image to add into list produces error message "file format not supported by image list editor". Uninstalling DevExpress fixes the issues. My guess is one of your property/component editors breaks the existing functionality.
To reproduce create a new project with one form and put TImageList on it. Double click on it and try adding a single bmp image to the list.
No problem here with the above, maybe you have a problem with TcxImageList (a much better Imagelist)
in which case reinstall everything from scratch.
Apart from that the standard TImageList is fine on 3 of our PCs with PNG,BMP and JPEG files…
Here's the thing: cxImageList works fine. It's just the delphi's ImageList that can't add bmps. ICO works fine.
And I should mention this behavior is limited to Delphi 2007. In XE all is fine.
Hello Johannes,
Thank you for your valuable report. I have reproduced the described behavior and forwarded this ticket to our developers for research.
