How to update map region using C to get to the next resolution? I have a raster map where I loop over data using Rast_get_row() and friends. Later I draw these pixels on a screen. Now to get a zoom functionality, I need to update region settings and then redraw the pixels. This is where I need some help.
Rast_get_window(&window) How to perform an update of "window" to move to next zoom level ?. I had looked code in gui/wxpython/core/render.py gui/wxpython/mapwin/buffered.py Hope someone with experience in wxgui rendering could help me in this case. Thank you in advance for help. -- Regards, Rashad
