Select off-screen pages for drawing and display, copy or scroll pages, and combine pages with AND/OR/XOR.
PAGE WRITE n | FRAMEBUFFER PAGE DISPLAY n PAGE COPY src [TO dst] PAGE COPY src, dst [, I|B] PAGE SCROLL n, x, y [, fillcolour] PAGE AND_PIXELS s1, s2, dest PAGE OR_PIXELS s1, s2, dest PAGE XOR_PIXELS s1, s2, dest
n - page number src, dst - source and destination pages B - skip black pixels when copying x, y - SCROLL moves the page right by x and up by y fillcolour - omitted wraps; -1 leaves the gap; any other colour fills it
WRITE selects the draw target (a page number or FRAMEBUFFER). DISPLAY shows page n. Every page is a normal pixel plane: page 1 is no different from the others and is only visible when selected with PAGE DISPLAY.
Example:
PAGE COPY 0 TO 1
PAGE SCROLL 0, 8, 0Source: docs/help/page.txt inmmcore. On the computer, typeHELP PAGE.
