我正在尝试将纹理应用于图像
原始
纹理
结果(由PHP GD制成)
但是使用SVG,我得到的最接近的结果是
<svg preserveAspectRatio="none" width="500" height="500" viewBox="0 0 500 500">
<defs>
<filter id="texture">
<feImage href="https://i.imgur.com/pjWcnJs.jpg" result="texture-img"/>
<feBlend in="SourceGraphic" in2="texture-img" mode="multiply"/>
</filter>
</defs>
<g>
<g filter="url(#texture)">
<image x="0" y="0" href="https://i.imgur.com/oVEdsQt.png" opacity="1" width="500" height="500" />
</g>
</g>
</svg>
还有另一种方法可以不对透明像素进行纹理化吗?
答案 0 :(得分:4)
我找到了一种解决方案,即将纹理通过复合滤镜,将其裁剪为源图像
<svg preserveAspectRatio="none" width="500" height="500" viewBox="0 0 500 500">
<defs>
<filter id="texture">
<feImage href="https://i.imgur.com/pjWcnJs.jpg" result="texture-img"/>
<feComposite in2="SourceGraphic" operator="in" in="texture-img" result="composite"/>
<feBlend in="SourceGraphic" in2="composite" mode="multiply"/>
</filter>
</defs>
<g>
<g filter="url(#texture)">
<image x="0" y="0" href="https://i.imgur.com/oVEdsQt.png" opacity="1" width="500" height="500" />
</g>
</g>
</svg>
要平铺纹理,我像这样使用feTile
<svg preserveAspectRatio="none" width="500" height="500" viewBox="0 0 500 500">
<defs>
<filter id="texture" x="0" y="0" width="100%" height="100%">
<feImage href="https://i.imgur.com/gWH7NLm.jpg" result="texture-img" width="256" height="256"/>
<feTile in="texture-img" x="0" y="0" width="100%" height="100%" result="tile" ></feTile>
<feComposite in2="SourceGraphic" operator="in" in="tile" result="composite"/>
<feBlend in="SourceGraphic" in2="composite" mode="multiply"/>
</filter>
</defs>
<g>
<g filter="url(#texture)">
<image x="0" y="0" href="https://i.imgur.com/oVEdsQt.png" opacity="1" width="500" height="500" />
</g>
</g>
</svg>
我通过检查inkscape
