This really is a gtk+ question, rather than a glade question.
Here is a section from the gtk+ documentation:
---
The pixels in a GtkPixmap cannot be manipulated by the
application after creation, since under the X Window system
the pixel data is stored on the X server and so is not
available to the client application. If you want to create
graphical images which can be manipulated by the
application, look at GtkImage and GdkRGB
---
In my latest application I use GdkRGB to display fractal images,
GdkRGB can do fancy things like dithering. GtkImage is more like
the GtkPixmap, but the image can be manipulated.
A GtkImage is created from a GdkImage. The GdkImage can be
manipulated with gdk_image_get_pixel and gdk_image_put_pixel.
I hope this will point you in the right direction.
