This descendant of TFPCustomImage stores the image data as TRawImage, and is therefore able to interchange images directly with the LCL interfaces.

A large number of the protected methods (GetColorxxxxxx and SetColorxxxxxx) deal with direct interface to the operating system at the pixel level

Usage examples:

    1. Loading a .xpm file into a TBitmap:

      var
        BmpHnd,MaskHnd: HBitmap;
        Bitmap1: TBitmap;
        IntfImg1: TLazIntfImage;
        Reader: TLazReaderXPM;
      begin
        // create a bitmap (or use an existing one)
        Bitmap1:=TBitmap.Create;
        // create the raw image
        IntfImg1:=TLazIntfImage.Create(0,0);
        // get the description for the current screen (bitsperpixel, depth, ...)
        IntfImg1.GetDescriptionFromDevice(0);
        // create the XPM reader
        Reader:=TLazReaderXPM.Create;
        // load the image
        IntfImg1.LoadFromFile('filename.xpm',Reader);
        // create the bitmap handles
        IntfImg1.CreateBitmap(BmpHnd,MaskHnd);
        // apply handles to the Bitmap1
        Bitmap1.Handle:=BmpHnd;
        Bitmap1.MaskHandle:=MaskHnd;
        // clean up
        Reader.Free;
        IntfImg1.Free;
        // do something with the Bitmap1
        ...
      end;


    2. Saving a TBitmap to a .xpm file:

      var
        BmpHnd,MaskHnd: HBitmap;
        Bitmap1: TBitmap;
        IntfImg1: TLazIntfImage;
        Writer: TLazWriterXPM;
      begin
        ...
        // create the raw image
        IntfImg1:=TLazIntfImage.Create(0,0);
        // load the raw image from the bitmap handles
        IntfImg1.LoadFromBitmap(Bitmap1.Handle,Bitmap1.MaskHandle);
        // create the XPM writer
        Writer:=TLazWriterXPM.Create;
        // save image to file
        IntfImg1.SaveToFile('filename.xpm',Writer);
        // clean up
        Writer.Free;
        IntfImg1.Free;
        ...
      end;
    }
