Blend sprite with solid color (blend mode color), ignore transparent pixels

[Dresel]

Hi, I'm porting a bit of SkiaSharp code which combines SKBlendMode.DstIn (Destination In) and SKBlendMode.Color (blend mode color) for a drawing operation (more or less a one liner of code).

I tried to apply this on a sprite, after lots of trial and error and research I came up with this:

• Create a Graphics object with the desired color and width / size of the original sprite, set blend mode 'color'
• Create a local Container, add a Sprite and the Graphics object, render it on a RenderTexture
• Create a Mask from the Sprite (by applying ColorOverlayFilter filter), render it on a RenderTexture
• Create a new Sprite, use the blended RenderTexture as texture and the rendered mask, render it on a RenderTexture
• Replace the original texture

// Blend texture with color
let overlay = new Graphics()
    .rect(0, 0, sprite.width, sprite.height)
    .fill(0xFF0000);
overlay.blendMode = "color";

let container = new Container();
container.addChild(new Sprite({ texture: new Texture({ source: sprite.texture.source, frame: sprite.texture.frame }) }));
container.addChild(overlay);

let blendedRenderTexture = RenderTexture.create({
    width: sprite.width,
    height: sprite.height,
});

application.renderer.render(container, { renderTexture: blendedRenderTexture });

// Create mask to filter out black pixels
let mask = new Sprite({ texture: new Texture({ source: sprite.texture.source, frame: sprite.texture.frame }) });
mask.filters = new ColorOverlayFilter({ color: 'white', alpha: 1 });

let renderedTextureMask = RenderTexture.create({
    width: sprite.width,
    height: sprite.height,
});

application.renderer.render(mask, { renderTexture: renderedTextureMask });

// Create the final texture
let blendedAndMasked = new Sprite(blendedRenderTexture)
blendedAndMasked.mask = new Sprite(renderedTextureMask);

let finalTexture = RenderTexture.create({
    width: sprite.width,
    height: sprite.height,
});

application.renderer.render(blendedAndMasked, { renderTexture: finalTexture });

// Replace the texture
sprite.texture = finalTexture;

• render(container: Container, options: { renderTexture: any; }): void; is marked as obsolete, how would I replace that with render(options: RenderOptions | Container): void;?
• Is this the way to go or can this be simplified?
