Re: [GRASS-dev] is r.in.png working in GRASS 7?
Thanks for the tips. I will try again. r.in.gdal worked fine. Maybe I just missed the created files from r.in.png like you said. Michael C.

Only problem was that I have fresh (new) xy location without reasonable default region and when I imported data and added them to layer manager, I saw only grey color. The problem was that I had to do "zoom to map" because my display was zoomed to one pixel (bbox 0,0,1,1). Another problem is that after import one map is added to layer manager. Unfortunately this map does not exist. It is map with the name same as the picture name. But there are three maps one for each color. This is a bug. But so far there are no ideas how to fix it.

[GRASS-dev] is r.in.png working in GRASS 7?
I just tried to use r.in.png to prepare a demo of georectifying for my class 1. I made a map from the sc demo data of roads, streams, and lakes 2. I exported it to PNG. Looks fine 3. I used r.in.png to import it. No error. 4. No map I tried the default settings and the floating point flag. Any ideas? Michael C.
