Description

constructor Create(AFormat, AWidth, AHeight: Integer);

function GetData(const Rect: TRect; Dest: Pointer; DestImageWidth: Integer): Boolean; virtual; abstract;

Copies a rectangular area of the specified mip level of the image to an image with width DestImageWidth and data located in memory at Dest and returns True if success

function GetDataAsRGBA(const Rect: TRect; Dest: Pointer; DestImageWidth: Integer): Boolean; virtual; abstract;

Copies a rectangular area of the specified mip level of the image to an RGBA image with width DestImageWidth and data located in memory at Dest and returns True if success

function LoadData(Rect: TRect; Dest: Pointer; DestImageWidth: Integer): Boolean;

Calls implementation-dependent GetData() to load image data

function LoadDataAsRGBA(Rect: TRect; Dest: Pointer; DestImageWidth: Integer): Boolean;

Calls implementation-dependent GetDataAsRGBA() to load image data
