Summary
Bitmap wrapper class for thread safe bitmap access.
Description
Defines a Bitmap wrapper class for thread safe bitmap access. Use this class when you need to access a bitmap from different threads.
Properties
Public
- PixelFormat - Specifies the pixel format of the bitmap.
- Height - The Height of the Bitmap.
- Width - The Width of the Bitmap.
- Canvas - Access the the drawing context of the bitmap.
- RawData - Returns pointer to the raw bitmap data.
Methods
Public
- procedure Resize(AWidth : Integer; AHeight : Integer) - Resizes the bitmap.
- procedure SetSize(AWidth : Integer; AHeight : Integer) - Resizes the bitmap.
- procedure SaveToFile(Filename : String) - Saves the bitmap to a bitmap file.
- procedure SaveToStream(Stream : TStream) - Saves the bitmap to a stream.
- procedure FromBuffer(APtr : PByte; AScanlineStep : Integer) - Populates the bitmap from a video buffer.
- procedure ToBuffer(APtr : PByte; AScanlineStep : Integer) - Populates a buffer from the bitmap data.
- procedure ToBitmap(ABitmap : TBitmap) - Copies the bitmap to a standard bitmap object.
- function GetDC() : HDC - Returns the Windows Device Context (DC) of the internal bitmap.
- function GetHBitmap() : HBITMAP - Returns the HBITMAP handle of the internal bitmap.
