By the way tr1p1ea, in the following screenshot showcasing the new Rectangle color shift feature (that wraps the color palette around by a value you want)



Is that the actual processing speed or did you add delays to prevent the screenshot from going too fast and skipping frames?

That is slow due to the way the test is ... its really bad lol:

each frame:
draw sprite
draw fullscreen rectangle with rotated colours
draw fullscreen black rectangle to destroy previous frame

Here is one with just the sprite:

Ive added support for 32 colour 160x120 images (scaled to fullscreen). These images are 12000bytes for image data + 32 bytes for the palette.

The 32 colours are not predefined and can be made up from a selection of the 256 colour xLIBC palette.

Example images:



Looks pretty sweet oncalc and offers more flexibility than the 80x60 bg images without taking up too much size*.

Yeah, pretty nice although it would look far better with pixel art. ;) Also, why the * ?

The * is because some people might not think that 12kb is a low size for an image :).

Yeah they are just quick image tests, if you were actually designing an image with 32 colours in mind it would look much better.

Awesome tr1p1ea :D. This might be handy for some title screens. Also this reminds me Sega Genesis and Game Boy color material.

By the way, something that would be cool for images if if besides their default palette, you could display that image with a custom palette too. Before calling the function, you would just store a string containing the palette in Ans or Str0 (preferably Ans) and if the function detects a valid string in there, it displays the image using the custom palette instead of the one inside the appvar. It could be handy if someone wants to re-use an image multiple times under different colors.

Hhmmm... due to the way xLIBC draws data to the LCD it might prove difficult, but i can look into it.

Bug report with xLIBC's DrawSpriteList8x8A command:

If you try to display a sprite and its X position is higher than 128 on the screen, it will not show up. For example, real(4,2,1,0,0,26,1,127,95,0 will work, but not real(4,2,1,0,0,26,1,128,95,0.

Nice work DJ i found the issue! I was doing treating the coordinates as 8-bit and sign extending into 16-bits ... this means that 128 gets changed to -128 :S!

Great work on finding this one, I have implemented the fix :).
