[Openev-discuss] Stationary Cross hair

[Sampson, D. <dsampson@NRCan.gc.ca>]

Hey folks,


I'm comparing some of the features between Open EV and other popular
proprietary free geo-image viewers.  One of the features that would be
nice to have that I have not found in OpenEV is a stationary cross hair
placed upon a mouse click over the image.

One of my workflow processes includes using a viewer to grab the pixel
and line values to be used as Ground Control Points (GCP) of an
un-georeferenced image.

This process involves moving the mouse to a given point over the image.
What would be required is a cross hair that can be placed at a given
location and have the line and pixel values remain visible for that
point while the mouse is moved to another application to input those GCP
values.

Currently I am using an alt-tab method to switch applications.
Furthermore the windows of both OpenEV and the application need to
overlap so that the pixel and line values do not dispaear when I move my
mouse off of OpenEV.

Does this make sense?

I am working wth Fwtools in Windows


Cheers
