JPEG display using GTK

[dgajudo]

Is it possible to display a JPEG image using gdk_draw_rgb_image()?

I think that I need first to read the JPEG image into an RGB buffer before using
this function. Any suggestion on how to do this.

I've already found a solution to display a jpeg image file using gdk_draw_rgb_image().
I have used the the IJG code to read the jpeg file into an RGB buffer.

Here's the code snippet:
===========================================
pic=malloc(3*320*240)

jpegread("filename", &width, &height, pic); //refer to libjpeg.doc at www.ijg.org

gdk_draw_rgb_image (pixmap,
drawing_area->style->white_gc, 0, 0, 320,
240, GDK_RGB_DITHER_NORMAL, pic,
960);

free (pic);
==========================================

You need to have the jpeglib.h and libjpeg.a to compile successfully.
