The images in question are ones produced in Adobe Photoshop and saved as Windows bitmaps (as opposed to OS2 files). When t try to load one of these images into a TBitmap i get a stream read error. My own investigation has lead me to the conclusion that for some reason the TStream object in TBitmap.ReadDIB is refusing to read the last two bytes of the pixel data. Does anyone know why this is happening? The images load perfectly in Windows and MS Paint.

Yes, read this QC report, it also has a work-around: http://qc.codegear.com/wc/qcmain.aspx?d=8398 This was fixed in Delphi 2005. - Asbjørn Back to top David J Taylor Guest Posted: Wed Apr 18, 2007 8:11 am    Post subject: Re: Delphi Bitmap Issue Vertuas wrote: Quote: Hi all I have a problem opening bitmap images from my delphi application.

Does anyone know why this is happening? The images load perfectly in Windows and MS Paint. Ta Adobe Photoshop writes invalid bitmaps. I had to update my own bitmap reading routines to bypass the problem. The fix to which Lord Crc pointed may work for you.
