[Qgis-user] QGIS Master and Rasters to grayscale

[James Stott]

I have included links to two example jpgs to show what happens. 1.9.jpg shows what happens when I use the method detailed below.

 

I would like the raster to display as in the 1.8 jpg.

 

QGIS 1.8 https://docs.google.com/open?id=0B6r5nAOdEBZrSjhyaHdoUW9LY0U

QGIS 1.9 https://docs.google.com/open?id=0B6r5nAOdEBZrLUJ1dDNNM3BJZVE

Hi James

You may go to the raster properties, select render type singleband gray. Then select contrast enhancement 'stretch to min/max' and click on 'load' to get the min/max values from the datasource.

Having this by default (options page) is not yet available with the new raster classes. A bugticket is already filled.

Regards,
Marco

I sometimes display my Ordnance Survey rasters  as single band gray to allow my data to show more clearly over the top of it.

 

In the new master I cannot achieve the same effect. My raster goes solid grey.

 

Old settings:

 

Render as: Single Band gray

Single band properties - gray band: Band 1

Single band properties - color map: grayscale

 

New settings:

 

Render type: Singleband gray

Gray band: Palette

Contrast enhancement: No enhancement

 

How do I achieve the same effect as before? The raster displays fine in colour, just not in grayscale. I am guessing it's down to the new raster properties in master.
