Synopsis
Some helpful static functions that are common to some of my image analysis application classes.
Motivation
I needed some bits and pieces. My goal isto move this rag-tag bunch out of here into other classes as time goes on. So far I have eliminated 80% of the original !
To Do
Definition at line 86 of file ImageUtilities.h.
This function converts pixel coordinates to world coordinates.
You specify a vector of pixel coordinates (pixels) for only one axis, the pixelAxis. For the other pixel axes in the CoordinateSystem, if a pixel axis "i" is found in the CursorAxes vector, its pixel coordinate is set to the average of the selected region from the image for that axis ((blc(i)+trc(i))/2)), otherwise it is set to the reference pixel.
The vector of world coordinates for pixelAxis is returned as formatted Strings. If for some reason it can't make the conversion, the element element is returned as "?" Returns False if the lengths of <blc and trc are not equal to the number of pixel axes in the coordinate system.
