Hello all An issue I face is different users' different GDAL versions meaning making Processing GDAL calls in a plugin difficult, as you have to get the arguments right:
https://github.com/tomchadwin/qgis2web/blob/v2.17.0/utils.py#L314 I've got these different argument lists wrapped in try: blocks, but was wondering if a different approach might be better. If I call, for example, processing.runalg("gdalogr:warpreproject") without arguments from the console, I get an error back: Error: Wrong number of parameters ALGORITHM: Warp (reproject) INPUT <ParameterRaster> SOURCE_SRS <ParameterCrs> DEST_SRS <ParameterCrs> NO_DATA <ParameterString> TR <ParameterNumber> METHOD <ParameterSelection> RAST_EXT <ParameterExtent> EXT_CRS <ParameterCrs> RTYPE <ParameterSelection> COMPRESS <ParameterSelection> JPEGCOMPRESSION <ParameterNumber> ZLEVEL <ParameterNumber> PREDICTOR <ParameterNumber> TILED <ParameterBoolean> BIGTIFF <ParameterSelection> TFW <ParameterBoolean> EXTRA <ParameterString> OUTPUT <OutputRaster> METHOD(Resampling method) 0 - near 1 - bilinear 2 - cubic 3 - cubicspline 4 - lanczos RTYPE(Output raster type) 0 - Byte 1 - Int16 2 - UInt16 3 - UInt32 4 - Int32 5 - Float32 6 - Float64 COMPRESS(GeoTIFF options. Compression type:) 0 - NONE 1 - JPEG 2 - LZW 3 - PACKBITS 4 - DEFLATE BIGTIFF(Control whether the created file is a BigTIFF or a classic TIFF) 0 - 1 - YES 2 - NO 3 - IF_NEEDED 4 - IF_SAFER Can I rely on getting this kind of output from all GDAL versions? If so, I can try to figure out the best way to parse out the arguments it needs, and supply them. Should this work?
