listgeo not printing corners correctly for PixelIsPoint

Reported by: normvcr Owned by: warmerdam
Priority: normal Milestone:
Component: Utilities Version: unspecified
Severity: normal Keywords: libgeotiff, listgeo, pixelIsPoint
Cc: normvcr@…

Description (last modified by normvcr)

In GTIFPrintCorners(), the following code/hack needs to be added at the very top:

if( PixelIsPoint? ) {

--xsize; --ysize;

}

For example, suppose an image extent has a width of 10m, with 5m pixels.

In PixelIsArea?, the image has 2 pixels in the width, centred at 2.5m and 7.5m.

In PixelIsPoint?, the image has 3 pixels in the width, at 0m, 5m and 10m.

This code comes from libgeotiff (and the source code of listgeo.c isn't even in GDAL sources), so the ticket should be open in libgeotiff bug tracker: http://trac.osgeo.org/geotiff/
