Descrizione
Hi @lovell, Does sharp support the option to dissolve a transparent image? I was looking for something similar to imagemagick's dissolve option. I took a look at the docs but could not find anything. What i wanna achieve is to overlay a watermark, which works well but i would also like to dissolve it by ~35%.
return sharp(watermark)
.resize(width)
.toBuffer()
.then((outputBuffer) => {
return stream.overlayWith(outputBuffer);
});
streamis the streamed base image andwatermarkis the watermark png file which i would like to dissolve.
