GrayShrink

view:GrayShrink(bitmap, style)

Anti-aliases a 1-bit pix family and renders it on the screen.

bitmap

A 1-bit pix family or bitmap graphic shape.

style

A style frame, as used by DrawShape. This frame should contain a transform slot representing a reduction in size, either horizontally, vertically, or both. The transform slot should contain two bounds frames, i.e. not two integers. You may pass nil for the source bounds frame, in which case, bitmap's bounds are used. You may also pass nil for the destination bounds, in which case the viewBounds slot is used.

return value

Undefined, do not rely on what this method returns.

DISCUSSION

If bitmap is not 1-bit, or if style does not have a transform slot representing a reduction in size, bitmap is still rendered on the screen, but not anti-aliased.
