Hi,
The internal FData field variable of TFPMemoryImage is of type
FPFItegerArray and is defined as follows:
TFPIntegerArray = array [0..(maxint-1) div sizeof(integer)-1] of integer;
PFPIntegerArray = ^TFPIntegerArray;
Unfortunately the FPImage unit is not documented at all. So I have the

Playing around further I've managed to get something kinda working. See
attached image. Left is what I now render via my 3rd party image
library, right is what it is supposed to look like.
Two points to note about the attached image:
1. The colours are obviously wrong.
2. The image seems

Oh, I forgot about Palette usage. I’ll have to check for that in my
code. Does setting UsePalette := False at runtime auto convert palette
data to RGB data? I had a lo

Probably due to Colors array usage. ;-)

Thanks for the information Mattias. In the end I managed with the
TFPCompactImgRGBA8Bit image type. From what I can remember, after some
experimentation, the internal channel information in memory was in BGRA
format.
