Reference TBitmapDataSDL

Declared in Codebot.Platform.SDL.pas on line 43

TBitmapDataSDL holds the pixels of a bitmap in memory. Pixels are stored as described by IBitmapData, premultiplied blue, green, red, and alpha with rows from top to bottom.

Images are decoded by SDL_image in any format it supports. SaveToFile writes a jpeg if the file name ends with .jpg or .jpeg, a bmp if it ends with .bmp, and a png otherwise. SaveToStream always writes a png.

  TBitmapDataSDL = class(TInterfacedObject, IBitmapData)
  public
    function GetWidth: Integer;
    function GetHeight: Integer;
    function GetPixels: Pointer;
    { Resize the bitmap and clear its pixels to transparent black }
    procedure SetSize(Width, Height: Integer);
    procedure LoadFromFile(const FileName: string);
    procedure LoadFromStream(Stream: TStream);
    procedure SaveToFile(const FileName: string);
    procedure SaveToStream(Stream: TStream);
    property Width: Integer read GetWidth;
    property Height: Integer read GetHeight;
    property Pixels: Pointer read GetPixels;
  end;
