Re: [GRASS-dev] What should d.erase do in the main wxGUI?

2014-10-16 Thread Helena Mitasova
Vasek,

the main reason we have d.erase in the assignments and in the book is for 
zooming to computational region,
including changing the resolution 

# for d.erase: Zoom to computational region and switch off previous map layers 

the manual page does not say it, probably because it was implied.
If possible it may be useful to have the zoom to region as a flag?
d.erase would just switch off the layers (I am not sure it should remove them - 
let us see what others say)
d.erase -r would remove the layers and zoom the display to computational region.

This would be extremely helpful in the assignments when switching to 3D view

[GRASS-dev] What should d.erase do in the main wxGUI?

2014-10-16 Thread Vaclav Petras
Hi,

in GRASS 7, the d.erase command is not supported in the main GUI.

For `d.mon wx0` d.erase removes all rasters and shows the backgroud.
d.erase bgcolor is ignored.

For `d.mon png` d.erase uses bgcolor as expected.

For the main GUI, the question is if the Layers in Layer Manager should be
removed or just unchecked. I'm for removing them.

The second question is if the background should be changed. The same
applies to `d.mon wx0`. The settings of background color in GUI is done
differently but perhaps d.erase can change the color temporary (I'm not
sure how hard this would be to implement).

Is there something else what d.erase is doing? I got the impression that it
zooms to computational region but manual page is silent about it.
