Excuse me，Ask a question ;)

var
    img: TImageData;
  begin
    Imaging.InitImage(img);
    Imaging.NewImage(512,512,ifBinary, img);
 
    Imaging.SaveImageToFile('Test.bmp', img);
    Imaging.FreeImage(img);
end;


the result 'Test.bmp' is ifR8G8B8

Can not save a black-and-white image of Binary format？

Lazarus1.0.2 Compiled  "VampyreImaging.lpi"
Generate "VampyreImaging.dll"

VC++ Run "test.c"
........................
/* save image to Targa format */
ImSaveImageToFile("ctestimage.png", &Img);  //Unable to generate images
DelphiXE3 Call VampyreImaging.dll //Unable to generate images too

but VampyreImaging.dll of DelphiXE3  Generated
generate images is OK.

How do I set Lazarus？
