Load JPG into cairo

[stefano.facchini]

How can I load a JPG image and use in cairo? cairo can load directly only the PNG format, but there must be (in gtk or elsewhere) some built-in library for handling other formats, for example something used by nautilus to show the thumbnails. Any suggestion?

thank you all!

You can always convert your .jpg image into .png format using convert from the imagemagick package or jpegtopnm/pnmtopng from the netpbm package. Surely there are other ways but I can't see a way to force cairo to accept a .jpg.

This really bugged me. I think the best way is to load the image file into a GdkPixbuf, then usegdk_cairo_set_source_pixbuf to load the image into your cairo context. So, (if you're trying to draw the image on a gtk window) the code might look something like this:



GdkPixbuf *image;
cairo_t *cr;

cr = gdk_cairo_create (window);
image = gdk_pixbuf_new_from_file("elephant.jpg");
gdk_cairo_set_source_pixbuf(cr, image, 0, 0);
cairo_paint (cr);
Correct me if I'm wrong.
