That unable to load from delphi either design & runtime. The BMP is 64x64 24 bits. Does anyone get the same problem? This is a photoshop or delphi bug?

This is a photoshop or delphi bug? Yes, i just got it. It seems that Photoshop stores an invalid value for the image size in the bitmap header. For a 256x256x24 image, it stores 2 bytes over the actual image size. This confuses delphi which relies on this info to be correct when present (for rgb images one can set it 0 and delphi will calculate the true value). The fix from my perspective is this: In TBitmap.ReadDIB, find this line: // biSizeImage can be zero. If zero, compute the size. if biSizeImage = 0 then // top-down DIBs have negative height Replace the if statement with this: if (bmiHeader.biCompression = BI_RGB) then this will force it to calculate the correct value for all non-compressed RGB images, which should work always (as an RGB image is per definition uncompressed, it just a matter of arithmetics). Ill enter it into QC soon. - Asbjørn Back to top mrjumbles Guest Posted: Thu Jun 10, 2004 10:34 pm    Post subject: Re: Photoshop & delphi~~ i have found that it only happens when the bitmaps dimensions are a multiple of 16.

Ah, nice catch. Now anyway, theres no need NOT to calculate the value as i can see, because as an uncompressed RGB image, its defined by its dimentions, and it's clearly the better route to take imho. - Asbjørn Back to top Wykis Guest Posted: Sun Jun 27, 2004 9:00 am    Post subject: Re: Photoshop & delphi~~ Why Don't You Try To Edit Image With "MS Paint" And Save It Into Another File?
