Arguments

`ASourcePixels`		the source pixel array.
`ASourceX`		the x coordinate of the top-left corner of the source area.
`ASourceY`		the y coordinate of the top-left corner of the source area.
`ASourceWidth`		the width of the source area in pixels.
`ASourceHeight`		the height of the source area in pixels.
`ASourcePitch`		the pitch of the source pixel array in bytes.
`ADestinationPixels`		the destination pixel array.
`ADestinationX`		the x coordinate of the top-left corner of the destination area.
`ADestinationY`		the y coordinate of the top-left corner of the destination area.
`ADestinationWidth`		the width of the destination area in pixels.
`ADestinationHeight`		the height of the destination area in pixels.
`ADestinationPitch`		the pitch of the destination pixel array in bytes.

Description

Copy an area of the source pixel array ASourcePixels to an area of the destination pixel array ADestinationPixels. ASourceWidth, ASourceHeight, ADestinationWidth and ADestinationHeight must all be positive integers. ASourcePitch and ADestinationPitch may be any value, even negative.

Warning: You must first call TPTCCopy.Request to initialize the pixel formats and TPTCCopy.Palette to initialize palettes.
