Re: [gtk-list] Displaying JPEGs

On 13 Feb, Mike Lindahl scribbled:
->  I am relatively new to GTK and am trying to get jpegs to display.  I am
->  using the libjpeg library and that is not a problem.  I have successfully
->  loaded the image into an array of memory.
->  
->  My problem comes in trying to display it.  My first idea was to use
->  successive calls to gdk_draw_point.  This works, however, it takes _way_
->  too long.  Since I am running on an 8-bit display, I also have to allocate
->  color entries (I am not entirely sure if I am doing this correctly,
->  but...).  
->  
->  What would be the correct way to get large images to display?
->  Should I be using pixmaps or some other object?
->  
->  I have read through some of the archives to the list, but have been unable
->  to find anything that solves my problem.  Does anyone know of any sample
->  code for loading an array of image data into a pixmap?  I also tried to
->  use things like gdk_pixmap_create_from_data (), but I don't know what
->  XImage format is, so that obviously didn't work.

there is a whole library designed just to do all of this:

save yourself a lot of work :)
