Resize image.

imageResize
TrueColorImage imageResize(MemoryImage msrcimg, int dstwdt, int dsthgt, const(char)[] filter, float gamma, float filterScale)

Resize image.

imageResize
void imageResize(void delegate(Color[] destrow, int y) srcGetRow, void delegate(int y, const(Color)[] row) dstPutRow, int srcwdt, int srchgt, int dstwdt, int dsthgt, int filter, float gamma, float filterScale)

Resize image. Partial gamma correction looks better on mips; set to 1.0 to disable gamma correction. Filter scale: values < 1.0 cause aliasing, but create sharper looking mips (0.75f, for example).

Get filter name. Will return null for invalid index.

imageResizeFindFilter
int imageResizeFindFilter(const(char)[] name, const(char)[] defaultFilter)

Find filter index by name. Will use default filter for invalid names.
