将Raphael SVG转换为图像(png等)客户端 [英] Convert Raphael SVG to image (png etc) client side
问题描述
我有一个小项目,用户使用Raphael构建图表,然后将组合图表导出到图像中以保存。
I have a small project where users construct a diagram using Raphael and then export the composed diagram to an image to save.
问题是它必须脱机运行。 http://www.nihilogic.dk/labs/canvas2image/ 将无法正常运行需要画布,而不是Raphael生成的SVG。
Problem is it has to run offline. http://www.nihilogic.dk/labs/canvas2image/ will not work as it requires a canvas, not the Raphael generated SVG.
有没有办法(javascript)可以从SVG导出图像?
Is there a way (javascript) that I can export an image from the SVG?
推荐答案
是的,这个重复的问题是一个很大的帮助。 canvg结合canvas2image将我排除在外。
Yes, that duplicate question was a big help. canvg combined with canvas2image sorted me out.
所以我用Raphael创建了SVG。然后在按钮上单击,将保存SVG的div的内部HTML保存在变量中,然后在canvg中使用它,隐藏SVG div。然后我可以使用canvas2image的画布ID。这对PNG来说真的很有效。
So I created the SVG using Raphael. Then on a button click, saved the inner HTML of the div holding the SVG in a variable, then used that in canvg, hiding the SVG div. I could then use the ID of the canvas for canvas2image. It only really worked well for PNG.
