 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

I expect this request wouldn't be a simple as I might think... What is the chance of expanding the 'ORIENTATION' parameter of the BLIT command to include a few bits representing 'SCALE', much like the 'TEXT' command uses? For example, &B001000 - default scale of 1:1 &B010000 - scale 2 times larger &B011000 - scale 3 times larger ... &B111000 - scale 7 times larger The scale value indicates how many times each pixel is repeated in the x and y directions. An even crazier possibility would be separate fields for x and y scales. We can dream, can't we? ========== I'll go back to IMAGE RESIZE_FAST now. Visit Vegipete's *Mite Library for cool programs. |

You don't need this. Just put the image on a spare page and then resize it using image resize then load it as a sprite |

After paying more attention to what I was reading in the description of the IMAGE RESIZE (& RESIZE_FAST) command, I see that it already does most of what I requested. There's no need to use a spare page or sprite-ification. Except maybe for speed issues. The only missing part is horizontal and/or vertical mirroring. Allowing negative values for new_width and new_height could be used to indicate mirror. Visit Vegipete's *Mite Library for cool programs. |
