Software scale, rotate, and warp of a rectangle on a page. BITMAP (or GUI BITMAP) plots a 1-bit image; type HELP BITMAP.
IMAGE RESIZE x, y, w, h, nx, ny, nw, nh [, page] IMAGE RESIZE_FAST … [, page] [, flag] IMAGE ROTATE x, y, w, h, nx, ny, angle [, page] IMAGE ROTATE_FAST … [, page] [, flag] IMAGE WARP_H x, y, w, h, x1, y1, h1, x2, y2, h2 [, page] [, flag] IMAGE WARP_V x, y, w, h, x1, y1, w1, x2, y2, w2 [, page] [, flag]
x, y, w, h - source rectangle nx, ny, nw, nh - destination rectangle (RESIZE) angle - clockwise degrees about the source centre (ROTATE; cropped to w by h) page - source page (write page or FRAMEBUFFER) flag - 1 skips black pixels
RESIZE uses bilinear sampling; RESIZE_FAST is nearest neighbour.
Example:
IMAGE RESIZE_FAST 0, 0, 10, 10, 100, 80, 40, 40Source: docs/help/image.txt inmmcore. On the computer, typeHELP IMAGE.
