|0006564||[JEDI VCL] 00 JVCL Components||major||always||2017-04-09 11:42||2017-07-10 03:02|
|Status||new||Product Version||Daily / GIT|
|Summary||0006564: JvDBImage shows "Bitmap image is not valid" to some kind of jpeg image.|
|Description||Some kind of jpeg image does not has the "JFIF" or "Exif" signature at stream offset 6 as procedure GraphicSignaturesNeeded expected.|
Simple workaround is to add:
RegisterGraphicSignature([$FF, $D8], 0 , TJPEGImage);
But I think we should add file ending signature examination since a valid jpeg file is always ended with 0xFF, 0xD9. (According to https://en.wikipedia.org/wiki/JPEG) [^]

1. can this particular JPEG file provided for further analysis?
2. what do other image processing applications say when you try to load this image in them?
I have uploaded the jpeg file, please check the attached file "header.jpg".
I have tried lots of graphic processing applications, including IrfanView, Paint.net, GIMP, Corel PaintShop pro, Adobe Photoshop. They all can open this file without problem.
