PROBLEM: bitmap in memory to gtkimage

["Prest Alessandro" <prest fisica uniud it>]

Hello,
I have a bitmap image loaded in memory which structure is a standard
bitmap structure (BITMAP Info Header).

I want to display this bitmap in a GDKimage, which routine should I call?

Is this correct:


gdkPix =
gdk_pixmap_create_from_data(NULL,(gchar*)img_out.data,640,480,2,fg,bg);

image = gtk_image_new_from_pixmap(gdkPix,NULL);



Where "(gchar*)img_out.data" is pointer to bitmap data.

With this procedure I get: "gdk_pixmap_create_from_data: assertion `data
!= NULL' failed"

Thanks in advance!
