Would RLE compression be efficient for this? I wonder if it would be too slow...

He could also make the 'medium sized' ones into multiple sprites displayed on a black background so that he doesn't have to save as much empty space.

I do sprites and stuff, so yeah.

Actually, there's a lot of compression he could do. The middle line could be represented as either a series of lines stacked vertically, sprites linked horizontally, or simple filling of the buffer data inside the line with $FF. I'm not sure which of these would be most compact, but he could simply do trial and error to see which works best. The comet-like image would best be represented as one combination of sprites that is simply redrawn at different x values every frame, and vertically flipped every other frame. As for the four-pointed star and the explosions, they have 4 and 7 distinct sizes respectively, the images for which would each have to be stored, but only once. They could then be redrawn in whichever multiple frames they appear in. Even better, these two shapes are symmetrical both horizontally and vertically, so you would only need sprites to represent one quadrant for each scaled version and draw the other three quadrants by flipping the sprites horizontally, vertically, or both.

EDIT: Scratch the line drawing idea, forgot you can't draw white lines.

About white lines, couldn't he just inverts the screen then draw black lines the re-invert the screen (to get around the lack of white lines support)?

In case you were wondering, I've been working on this for you FinaleTI. So far I have the first 9 frames done at only about 800 bytes. With things like the header and the Pt-On() ignored, as these would already exist if it were part of your larger program, it's more like 650 bytes.

The hardest part is making a routine to draw horizontally and vertically symmetrical sprites of arbitrary size correctly, so you'll only need one quarter of the data you would otherwise need for the star and explosion images. But it's coming along.

EDIT: Now the hardest part is converting about 800 bytes of picture into 100 individual 8x8 sprites.

wow nice. That seems hard, though. Good luck! Will there be a lot of hard coded stuff??

I do have some BASIC programs I made to grab 8x8 sprites from a picture, I you wanna use them. They do require Celtic III/DCS7, but I could change that if you need.

Enjoy :) Subtract the header and the size of the Pt-On() routine and it's only slightly larger than 2 pictures!

I'm not sure what's more impressive: the compression used to make this or the amount of detail in those comments.

Either way, it looks great on calc. Nice work, Runer112 ;D

Runer: that is amazing and i now know who to contact(assuming you have the time) when trying to deal with picture compression(which i am anticipating to be a huge issue in what i am currently working on)
