Indexed Color Drawing?

[Shadowblitz16]

I don't know if true indexed color drawing is possible but can we have the ability to map colors to other colors?

Where did you see this? Any code examples? Any suggestions on how this would look?

[Shadowblitz16]

public record ColorMap(Color Source, Color Target);
public record Palette(ColorMap[] colors);

@generalloki winforms has support for color mapping with Palette and ColorMap
I was going to use it for yy-chr style graphics but supporting every old school game console graphics format would take your time out of improving alternate ui.

if your interested in supporting indexed graphics go look up yy-chr but even winforms doesn't support indexed graphics,
So I just suggested something like winforms colormap with drawing and images

sorry accidentally closed it

I am moving this to discussions.

@generalloki maybe a MapColor event would be better?
There needs to be some sort of support for effects.

We have added SKCanvas support (SkiaSharp). This canvas has many different features. Among them (I beleive) there is color mapping.

@generalloki can we get compressed image drawing?
Meaning drawing image data less then 8 bits?

I would love to see support for drawing raw pixel data down to 1 bit per pixel without expanding it in memory. Palette data could be passed to the draw method instead of being part of the image data.

I ask this because color mapping only goes so far.
I want to store super compressed image data.

Our current strategy is the following: Provide some basic level painting via Graphics/Image. And suggest to use SkiaSharp for any advanced painting. I think SkiaSharp might support what you are seeking but I can not give any clues as never worked with 1 bit per pixel images.

We do have Bitmap(int width, int height, int depth = 32) constructor. So you can probably pass depth 1 there and it will be bw image. But I am not aware how it will behave on different os and we did not perform any tests with such bitmaps. We just pass depth to wxWidgets and who knows how it works in case of bw bitmaps.
