The following code does it:
// your original data assumed to be in a continous structure of gray.
// Preferably in a structure.
float *src_buf;
int img_width = 256;
int img_height = 256;
// You destination
GdkPixbuf *dst = gdk_pixbuf_new(...);
guint8 *dst_buf = gdk_pixbuf_get_data();
guint src_st
Thanks for reply.
Can you please elaborate more on Converting More than 8bit image to 8
bit image.
And, apart from GtkImageView, is there no other way of image scaling?
Thanks

Even if your image has more than eight bits you can always convert it to
8-bit according to a user setting defining the grey level max and min to be
used for the convertion (known as window and level in the medical image
community). That's exactly how I do it in my image viewer giv. The image is

Hi all,
I have noticed that there is a way to load an animation using
gdk_pixbuf_animation_new_from_file.
But is there a way to save already loaded/created animation to a file?
For example GdkPixbuf has a method gdk_pixbuf_save
Thanks in advance,

Hi all,
Reading this list, I see some questions which talk about "threads": main
thread, event thread, and so on.
I was not conscious Gtk+ was multithreaded. I'm conscious of asynchronous code
with the mail loop and idle function (which are rather in Glib, I believe ?),
but really not of multi
Hi
I need to do some image manipulation using GTK, and I want to view some
proprietary image formats. So, I can prepare RGB data. But, which widget
and API to be use to draw pixels on screen.
I used GtkImage using Pixbuf, but it supports only 8 bits per sample.
Then I used GtkDrawing area,
