Hi All
I have:
unsigned char* imagedata.
I also have a function(pnm.c) that reads in a greyscale pgm image and return a pointer to the beginning of data. this is stored in " imagedata".
then to display the image i use the following:
glRasterPos2i(0,0);
glPixelZoom(1.0,-1.0);
glDrawPixels(w,h,GL_LUMINANCE,GL_UNSIGNED_BYTE,(const uchar*)imagedata);
w,h are the width and height of the image.
but when i run the program i get a memory read error. it says memory cannot be read.
Can someone suggest me a fix to this problem???
thanx in advance.
