alphaBlend32bit

void alphaBlend32bit(uint* src, uint* dest, size_t length)

Implements a two plus one operand alpha-blending algorithm for 32bit bitmaps. Automatic alpha-mask generation follows this formula: src[B,G,R,A] --> mask [A,A,A,A]

alphaBlend32bit

void alphaBlend32bit(uint* src, uint* dest, size_t length, uint* mask)

Implements a three plus one operand alpha-blending algorithm for 32bit bitmaps. For masking, use Pixel32Bit.AlphaMask from CPUblit.colorspaces.

alphaBlend32bit

void alphaBlend32bit(uint* src, uint* dest, uint* dest1, size_t length)

Implements a three plus one operand alpha-blending algorithm for 32bit bitmaps. Automatic alpha-mask generation follows this formula: src[B,G,R,A] --> mask [A,A,A,A]

alphaBlend32bit

void alphaBlend32bit(uint* src, uint* dest, uint* dest1, size_t length, uint* mask)

Implements a four plus one operand alpha-blending algorithm for 32bit bitmaps. For masking, use Pixel32Bit.AlphaMask from CPUblit.colorspaces. Output is copied into a memory location specified by dest1.

blitter16bit

void blitter16bit(ushort* src, ushort* dest, size_t length)

Two plus one operand blitter for 8 bit values. Automatic mask-generation is used from the source's color index with the following formula: mask = src == 0x0000 ? 0xFFFF : 0x0000

blitter16bit

void blitter16bit(ushort* src, ushort* dest, size_t length, ushort* mask)

Three plus one operand blitter for 8 bit values. An external mask is used for this operation.

blitter16bit

void blitter16bit(ushort* src, ushort* dest, ushort* dest1, size_t length)

Three plus one operand blitter for 8 bit values. Automatic mask-generation is used from the source's color index with the following formula: mask = src == 0x0000 ? 0xFFFF : 0x0000 Result is copied into memory location specified by dest1.

blitter16bit

blitter32bit

void blitter32bit(uint* src, uint* dest, size_t length)

Two plus one operand blitter for 32 bit values. Automatic mask-generation is used from the source's alpha channel with the following formula: mask = src.alpha == 0x00 ? 0xFFFFFFFF : 0x00000000

blitter8bit

void blitter8bit(ubyte* src, ubyte* dest, size_t length)
