Re: [Qgis-user] Python Skript for Saving

[Sebastian Teßmer]

Hi Carlos,

many thanks. I try out.
I would like to solve this in QGIS and also for a WMS service.
Is this possible?

Sebastian

Hi,

Yes, but It's better in list, always somebody that could correct me!!!

 

Firstly you must to visit this website:

http://www.gdal.org/index.html

 

Then, probably you need to use gdal_translate for convert rasters.

 

If you use windows you could write a bat for to do a list of conversions...

If you have linux you must to do a shell.

 

For example (bat for convert a lots of Mr Sid to TIF):

set SRC="">

REM start for

for /R %%f in (*.sid) do (

REM convert to geotif

call gdal_translate -a_srs EPSG:%SRC% "%%f" "%%~dpnf.tif" -co COMPRESS=JPEG -co JPEG_QUALITY=60 -co BLOCKXSIZE=128 -co BLOCKYSIZE=128

REM create pyramides

call gdaladdo -r average --config COMPRESS_OVERVIEW JPEG --config PHOTOMETRIC_OVERVIEW YCBCR --config INTERLEAVE_OVERVIEW PIXEL --config JPEG_QUALITY_OVERVIEW 80 "%%~dpnf.tif" 2 4 8 16 32 64 128 256

)

 

Good luck,

Hi Sebastian,

You could use gdal library directly!

 

Best regard,

Hello there,
I want to write a script that uses the "Save As" dialog.
What is the command for this in the Python console?
I want to store a lot of pictures, so they can be used offline.
Perhaps there is already a script for this?


Many thanks,

Sebastian
