javascript - Nodejs create a PNG image with text inside -


i'm trying create new png file serve clients via http (as response type image/png)

the new file created concatenating 3 base png files , adding custom text in middle of image.

problem is, there no built-in library in nodejs this. spent couple of hours searching , surprise, there no pure js library this. closest thing node-pngjs lacks ability add text. understand text part complicated since it's dependent on os (fonts installed, dlls interface said fonts, etc).

there other node modules wrappers around imagemagick (gm) , gtk (canvas) unfortunately imagemagick 155mb of binaries, , use canvas need compile source, install python , vs 2010 c++ express edition , not work on lastest version of gtk.

the best got right write .net assembly , use inside node via edge.js, require both windows os , .net framework on server.

again, complicated part here adding text inside image.

any suggestion on how working without sh**load of external dependencies?

yes correct, node.js support image processing libraries weak, wrappers of cli application.

the solution use involves phantomjs has canvas , svg support, use these features. it's lighter other options , not require external applications installed. http://phantomjs.org/quick-start.html
