Title Body

I have some code that looks like this: cairo_surface_t * surface = cairo_svg_surface_create("0.svg", 512, 512); cairo_t * context = cairo_create(surface); int * data = new int[512*512]; // fill the data... cairo_surface_t * image_surface = cairo_image_surface_for_data(data, 512, 512, 512*4); cairo_set_source_surface(context, image_surface, 0, 0); cairo_paint(context); // do some other drawing ... cairo_surface_flush(surface); cairo_surface_finish(surface); cairo_surface_destroy(surface); cairo_destroy(context); However, the svg always appears corrupted. The image is not properly written, and all drawing commands following do not work. Changing the surface type to PS, ie: cairo_surface_t * surface = cairo_ps_surface_create("0.ps", 512, 512); produces a perfectly correct PS document. Any help fixing the SVG would be appreciated. EDIT: Forgot to provide version info. Cairo 1.10.2 as given by cairo_version_string(). g++ 4.52 Running on Ubuntu 11.04 EDIT(2): Ok, I have traced this down to PNG problems with cairo and discovered that cairo_surface_write_to_png does not behave as expected either. Both this function and attempting to embed an image in an SVG cause "out of memory errors", and I still don't know why.
