I have been working with the examples/testers from<br>
<br>
# Project: GDAL/OGR Test Suite<br>
# Purpose: Test RasterizeLayer() and related calls.<br>
# Author: Frank Warmerdam &<a href="mailto:lt%3Bwarmerdam@pobox.com">lt;warmerdam@pobox.com</a>&gt;<br>
<br>
If at all possible, I would like to be able to use the memory raster<br>
contents directly. However, if I understand the code, the image is written<br>
in a more concrete format (gtiff, etc.) to the file system. The image can<br>
then by read back using the ReadAsArray method.<br>
<br>
The intended use is for display (e.g., 1000 x 1600) rather than fine grained<br>
printing. Also, if the memory area is more accessible, it might be possible<br>
to manage the application as a series of images, keeping more static ones<br>
unchanged, while updating dynamic parts, with the display being a merge of<br>
the two.<br>
<br>
gdal and ogr are nearly ideal for the application (generating georeferenced<br>
images, lines, etc.). Are there examples of how operate without the file<br>
write or is this a feature that could be added?<br>
<br>
Regards,<br>
<br>
Julianne<br>
