Do you change items of "arrayin" later? If so the items of the result array
will be changed too, dynamic array assignment copies the data pointer only.

never mind! The max color value is 65535. I thought it was 1.0 or 255. Got it
working now. Thanks again.

It is slightly confusing. If you are using an Indexed image, then use
the Pixels[] property. If you are not using an Indexed image, then use
the Colors[] property.
Attached is an example program that ge

The easy answer is just to use the system unit and have no fear...
The main issue with using fpc with C is when you try to use classes or try
to use C++ classes

Hello.
With this code, the result of the function does not have same format as the
array input:
Why ?
type
TArFloat = array of cfloat;
function array_in_out(arrayin: TArFloat): TArFloat;
begin
result := arrayin;
end;
Some more explaination.
If in a code I use:
var
thebuffer: TArFloat;

Hello,
What is the best FPC library able to remove EXIF data from a JPG file?
I would prefer to avoid the usage of external tools like ExifTool.
Thank you in advance for your suggestions.

Use the Colors property, it is fast:
property Colors [x,y:integer] : TFPColor read GetColor write SetColor
I’d like to draw a bitmap pixel by pixel then save to disk but I can’t understand the docs available online. I know there’s a BGRABitmap class with direct pixel access but I wasn’t able to find the unit in my FPC distribution.I used the image canvas before to draw bitmap fonts so I have this code w
