Render IMG to file?

[ursh]

Is it possible to render the plots directly to a image file.

I've got a lot of background reporting (in pdfs), where I use pre-
generated .png images for inclusion.

Currently im using jpGraph for all my plots but I'd like to switch to
jqplot as it think that this is the future!

I have thought about it and it is most likely possible. It would
probably involve some work to hook up, though.

There is a js package, Canvas2Image, which can convert a canvas tag to
image data. I do have on my todo list to offer a "plot2image" plugin
for jqPlot using this for imaging and printing. I have no timing yet.

I have never used Canvas2Image, so I don't know what it will take to
make it work. At the very least, non-canvas items have to be converted
to render their content on a canvas. This would be the legend, axes,
and title. I already have a canvas axes plugin. I will have to also
create canvas legend and title plugins.

Also, I think all of the canvases may have to be collapsed into one
canvas for imaging. I have not really looked at how Canvas2Image
works, but this is probably the case. I would then have to collect
all the canvases (the grid, series, axes, etc.) and draw them on one
"image" canvas.
