how can I colorize an Image with HTML5-Canvas? Based on an Hex- or RGB- Color Value as input?

答

尝试 CamanJS 。

Colorize过滤器看起来像你想要的： http://camanjs.com/docs/filters.html#section-13

The Colorize filter looks like exactly what you want: http://camanjs.com/docs/filters.html#section-13

将
图像中的颜色均匀移向给定颜色。

Uniformly shifts the colors in an image towards the given color.

调整范围是从0到100.
值越高，给定调整颜色的图像中的
颜色越接近
。

The adjustment range is from 0 to 100. The higher the value, the closer the colors in the image shift towards the given adjustment color.

Caman("#image", function () {
    // Explicitly give the R, G, and B values of the
    // color to shift towards.
    //
    // Arguments: (R, G, B, strength)
    this.colorize(25, 180, 200, 20);

    // The other way is to specify a color in hex form:
    this.colorize("#4090D5", 20);
});
