Hi monks!
Now I'm going to do those things:
1. Create a bitmap, each pixel's darkness is generated from some data value.
2. Draw some rulers and texts on that bitmap.
3. Output to PNG or JPEG.

It seems a mix of Cairo, Gdk Pixbuf, and Gdk could do that. However, the object construction order is pretty puzzling. There are several objects that I should work on, each one is build on someone another. For example, a cairo context is build on a cairo surface. Now, it seems those mess of things have some relation on my work:
- Cairo context
- Cairo surface
- Gdk Pixbuf
- Gdk Drawable

and I have a 2-dim matrix data which should be used as the source of bitmap. How can I build these messes up, and eventually got a CairoContext?
Thanks!

In reply to Gdk, Pixbuf, Cairo, build them up by llancet
