Class TGopBitBlt

class TGopBitBlt : public TGraphicsOperation;

Description

An accelerated graphics operation that copies a rectangular region of one bitmap into another.

The data members are all initialised on construction. Objects of this class can be passed to a graphics accelerator's Operation() function either individually, or in a buffer.

Derivation

• TGraphicsOperation - Abstract base class for all graphics operations

• TGopBitBlt - An accelerated graphics operation that copies a rectangular region of one bitmap into another

inline TGopBitBlt(const TPoint &aDestination, TAcceleratedBitmapSpec aSourceBitmap, TRect &aSourceRect);

Description

Constructor with a position, a source bitmap handle and a rectangle.

Parameters

const TPoint &aDestination The destination for the top left hand corner of the portion of the source bitmap. TAcceleratedBitmapSpec aSourceBitmap A handle to the source bitmap, and other information needed to draw it. TRect &aSourceRect A rectangle within the source bitmap.
