TRSGPBitmap.Pixels[Integer,Integer] Property

Delphi

public
  property Pixels[X, Y: Integer]: TRSGPColor read GetPixels write SetPixels;
 

Depending on the format of the bitmap, the Pixel property might not return the same value as was set by using it. For example, if you set a pixel whose pixel format is 32bppPARGB, the RGB components are premultiplied. A retrieval of the Pixel property might return a different value because of rounding. Also, if you set a pixel on a bitmap whose color depth is 16 bits per pixel, information could be lost in the conversion from 32 to 16 bits, and a subsequent examination of the Pixel property might return a different value.
