Implementation

pub fn updateImageSource(self: *Texture, src: ImageSource) !void {
    switch (src) {
        .imageFile => |f| {
            const img = try Color.PMAImage.fromImageFile(f.name, dvui.currentWindow().arena(), f.bytes);
            defer dvui.currentWindow().arena().free(img.pma);
            try update(self, img.pma);
        },
        .pixels => |px| {
            const copy = try dvui.currentWindow().arena().dupe(u8, px.rgba);
            defer dvui.currentWindow().arena().free(copy);
            const pma = Color.PMA.sliceFromRGBA(copy);
            try update(self, pma);
        },
        .pixelsPMA => |px| {
            try update(self, px.rgba);
        },
        .texture => @panic("this is not supported currently"),
