问题 I have an HTML/JavaScript program that uses the HTML5 canvas to generate a pretty graph: I want to include this graph in a book that I'm producing with LaTeX. Unfortunately, when I print this page to PDF, I get a bitmap—presumably because canvas is a bitmap. I just checked and apparently if I had developed this with SVG instead of with HTML5 canvas I would be good to go. But I didn't. So is there any way to generate line art from HTML5 Canvas, or should I just bite the bullet and re-implement

问题 Good day, I have read all questions and answers about "PDF to SVG", "PDF to PNG, PNG to SVG" and had no success in accomplishing my task. I have a PDF that is about 10mb (blueprints from archiCAD) and after using pdf2svg to convert to SVG, the SVG is about 70mb. Conversion takes 14sec, but the web page load takes about 150sec because of the size of the SVG. My question is - how can i convert PDF in PHP to SVG with appropriate size for web without quality loss and without gzipping it? This

问题 Looking to adjust the tonal values of the green color channel in an image. Specifically, changing the green values (only) to really dark green or black. Any ideas using svg filters? 回答1: You want the SVG feColorMatrix with type="matrix" . Then discard the Red/Blue channels, and multiply the green-to-green to be darker. Specifically, to turn an RGBA image to use just the green channel and darken it by half (and have full alpha no matter what the original alpha was), you want these matrix
