#1459 closed defect (fixed)

wrong pixel returned by wcps

Reported by: vmerticariu Owned by: vmerticariu
Priority: major Milestone: 9.4
Component: petascope Version: development
Keywords: Cc:
Complexity: Medium


When doing the transformation from geo coordinates to grid coordinates on axes with negative resolution, wcps returns a different pixel (offset 1). This happens in CoordinateTranslationService? on the branch handling linear negative axes.

To test: import a georeferenced image (Lat, Long), then select a pixel at some lat long with wcps, and select the same with qgis. The values will be different. To find the real value you have to select from wcps the pixel at the same long,but at lat + or - one resolution.
