Hi
New list member. I'm more of a science guy
1st/programmer 2nd. I'm a Physics prof at a small Univ in OK and I'm
doing a sabbatical with the National Severe Storms lab in Norman. I have
successfully written a couple of small Gnome apps that display lightning data
loops, etc.
My problem is that I want to be able to generate an
image with code that runs strictly from the command line. The Linux box I
need to use, boots into the command line - no GUI has been started. I
just want to set up a pixmap in memory, draw on it (lines, circles, points
based on data in files) and then read out the pixels into a simple image
file (*.ppm). It compiles OK using
g++ -Wall -o DrawTest DrawTest.cc `gtk-config
--cflags --libs`, but when it runs I get a segmentation fault/core dump
message. I whittled down the code so there's only two lines left (it
crashes on the 2nd one)!
#include <stdlib.h>
#include <stdio.h> #include <gtk/gtk.h> int main(int argc,char *argv[])
{ GdkPixmap *pixmap; pixmap =
gdk_pixmap_new(NULL,400,400,8);
/* ------stuff--- */
}
I really did try to dig through my books first, but
everything is geared toward being in a windowing environment. Can I do
this with the GDK library? I would greatly appreciate any advice anyone
might have. Thanks.
