Parameters

Parameters	Description
Image pifDest	Destination image
Image pifSrc	image to copy from
S_32 xd	destination x coordinate
S_32 yd	destination y coordinate
_32 wd	destination width (source image width will be scaled to this)
_32 hd	destination height (source image height will be scaled to this)
S_32 xs	source x coordinate (where to copy from)
S_32 ys	source y coordinate (where to copy from)
_32 ws	source width (how much of the image to copy)
_32 hs	source height (how much of the image to copy)
_32 nTransparent	Alpha method...
_32 method	specifies how the source color data is transformed if at all. See BlotMethods ... : possible extra parameters depending on method Method == BLOT_MULTISHADE extra parameters
red	Color to use the red channel to output the scale from black to color
green	Color to use the red channel to output the scale from black to color
blue	Color to use the red channel to output the scale from black to color Method == BLOT_SHADED extra parameters
shade	_nt_

Description

Copies some or all of an image to a destination image of specified width and height. This does linear interpolation scaling.

There are simple forms of this function as macros, since commonly you want to output the entire image, a macro which automatically sets (0,0),(width,height) as the source parameters to output the whole image exists.
