I have been working with the examples/testers from
# Project: GDAL/OGR Test Suite
# Purpose: Test RasterizeLayer() and related calls.
# Author: Frank Warmerdam <warmerdam at pobox.com>
If at all possible, I would like to be able to use the memory raster
contents directly. However, if I understand the code, the image is written
in a more concrete format (gtiff, etc.) to the file system. The image can
then by read back using the ReadAsArray method.
The intended use is for display (e.g., 1000 x 1600) rather than fine grained
printing. Also, if the memory area is more accessible, it might be possible
to manage the application as a series of images, keeping more static ones
unchanged, while updating dynamic parts, with the display being a merge of
gdal and ogr are nearly ideal for the application (generating georeferenced
images, lines, etc.). Are there examples of how operate without the file
write or is this a feature that could be added?
