| 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. | |||||||||||
| Additional Information |
Simple workaround is to add: RegisterGraphicSignature([$FF, $D8], 0 , TJPEGImage); to procedure GraphicSignaturesNeeded; 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) [^] |

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. |
