How to draw mask image in skija?

[peter158]

I want to draw the two pictures together to realize the function of picture mask, just like css style mask-image , So I want to know if any ways to use mask-image in skaji?

Looking forward to your reply thanks

Good question! I would look into ImageFilter::makeBlend, specifically one of

    /** Source trimmed inside destination. */
    SRC_IN,
    
    /** Destination trimmed by source. */
    DST_IN,

BlendModes
