Feature Request: Allow background image to be pixel/fragment shader specified by me #7013
Labels
Area-Extensibility
A feature that would ideally be fulfilled by us having an extension model.
Area-Rendering
Text rendering, emoji, complex glyph & font-fallback issues
Help Wanted
We encourage anyone to jump in on these.
Issue-Feature
Complex enough to require an in depth planning process and actual budgeted, scheduled work.
Product-Terminal
The new Windows Terminal.
Resolution-Fix-Committed
Fix is checked in, but it might be 3-4 weeks until a release.

Sounds like a cool extension idea. Related: #6242 |

Okay this is pretty slick not gonna lie. I'd again accept this as a community contribution, probably in the same vein as the experimental retro effects, until we get extensions sorted out. See also #4000. |

Co-authored-by: mrange <[email protected]> I loved the pixel shaders in #7058, but that PR needed a bit of polish to be ready for ingestion. This PR is almost _exactly_ that PR, with some small changes. * It adds a new pre-profile setting `"experimental.pixelShaderPath"`, which lets the user set a pixel shader to use with the Terminal. - CHANGED FROM #7058: It does _not_ add any built-in shaders. - CHANGED FROM #7058: it will _override_ `experimental.retroTerminalEffect` * It adds a bunch of sample shaders in `samples/shaders`. Included: - A NOP shader as a base to build from. - An "invert" shader that inverts the colors, as a simple example - An "grayscale" shader that converts all colors to grayscale, as a simple example - An "raster bars" shader that draws some colored bars on the screen with a drop shadow, as a more involved example - The original retro terminal effects, as a more involved example - It also includes a broken shader, as an example of what heppens when the shader fails to compile - CHANGED FROM #7058: It does _not_ add the "retroII" shader we were all worried about. * When a shader fails to be found or fails to compile, we'll display an error dialog to the user with a relevant error message. - CHANGED FROM #7058: Originally, #7058 would display "error bars" on the screen. I've removed that, and had the Terminal disable the shader entirely then. * Renames the `toggleRetroEffect` action to `toggleShaderEffect`. (`toggleRetroEffect` is now an alias to `toggleShaderEffect`). This action will turn the shader OR the retro effects on/off. `toggleShaderEffect` works the way you'd expect it to, but the mental math on _how_ is a little weird. The logic is basically: ``` useShader = shaderEffectsEnabled ? (pixelShaderProvided ? pixelShader : (retroEffectEnabled ? retroEffect : null ) ) : null ``` and `toggleShaderEffect` toggles `shaderEffectsEnabled`. * If you've got both a shader and retro enabled, `toggleShaderEffect` will toggle between the shader on/off. * If you've got a shader and retro disabled, `toggleShaderEffect` will toggle between the shader on/off. References #6191 References #7058 Closes #7013 Closes #3930 "Add setting to retro terminal shader to control blur radius, color" Closes #3929 "Add setting to retro terminal shader to enable drawing scanlines" - At this point, just roll your own version of the shader.

Description of the new feature/enhancement
Shadertoy.com has many amazing examples what one can do with what is called fragment/pixel shader. I would like to be able to download or implement my own pixel shaders and have that as a background in the terminal.
For exampel this one would be cool (making a bit darker to actually see the text) : https://www.shadertoy.com/view/3lyXDm
Configuring the feature be used using already existing background image but with support for shader file extensions?
