Hi there,First I would define the call 'gdk_pixbuf_new_from_data()' in the configfile as follows:
FUNCTION_NAME = gdk_pixbuf_new_from_data, NONE, WIDGET, 9, STRING, LONG, BOOL, LONG, LONG, LONG, LONG, NULL, NULL
The keyword 'STRING' in fact represents a C character pointer. If you define your image somewhere in memory, and pass the pointer to that memory as a number here, it should work.
If you plan to use 'gdk_pixbuf_get_pixels()' as well: FUNCTION_NAME = gdk_pixbuf_get_pixels, NONE, STRING, 1, WIDGETThis will return a (char-) pointer, which in fact is a number pointing to memory.
Please let me know if this works. Regards Peter Quoting Guillaume Legris <glegris@xxxxxxxxxxxx>:
Hi, I'm writing a (TCP-based) Java client for GTK-server and I need to draw an array of pixels created from the Java side. I tried gdk_draw_point (as shown in http://www.gtk-server.org/fractal.ksh) but it's too slow when there are too many pixels to write. I would like using gdk_pixbuf_new_from_data() and/or accessing to the pixbuf pixels with gdk_pixbuf_get_pixels (pixbuf) instead. How could I pass an array to the gdk_pixbuf_new_from_data() method ? Is there a way to access to the pixels ? Thanks in advance. Regards, Guillaume Legris
