Hi all,
I m trying to take a small part of an image and then use the
information of the small part to generate a new image.
following is my code can someone please point out where am i going
wrong and proab give me some suggestions.
The arrow points to where the program crashes.
Display *disp;
ImlibData *id;
XSetWindowAttributes attr;
Window win;
ImlibImage *im;
Pixmap p,m;
int w,h;
if (argc<=1)
{
printf("Usage:n %s image_filen",argv[0]);
exit(1);
}
disp=XOpenDisplay(NULL);
id=Imlib_init(disp);
im=Imlib_load_image(id,argv[1]);
w=im->rgb_width;h=im->rgb_height;
unsigned char* data;
ImlibImage *newIm; ImlibImage *newId;
int i,j;
unsigned char* data;
ImlibImage *newIm; ImlibImage *newId;
int i,j;
for(i=190;i<280;i++)
{
for(j=215;j<283;j++)
{
=> data[3*(i+w*j)+0] = (im->rgb_data[3*(i+w*j)+0]);
data[3*(i+w*j)+1] = (im->rgb_data[3*(i+w*j)+1]);
data[3*(i+w*j)+2] = (im->rgb_data[3*(i+w*j)+2]);
}
}
unsigned * val;
newIm = Imlib_create_image_from_data(newId,data,val,100,68);
thanks in advance
jay
