Hi,
Thank you
Hi,
If your output is 8 bit you can just use -scale without min/max values.
From https://gdal.org/programs/gdal_translate.html:
"Rescale the input pixels values from the range src_min to src_max to the
range dst_min to dst_max. If omitted the output range is 0 to 255. If
omitted the input range i
Hello GDAL team and thank you for welcome me.
I have an issue with the gdal_translate command. I would like to use the
STATISTICS_MIN and STATISTICS_MAX metadata key values in the -scale
parameter of the program, so I dont need to specify it manually every time
I want to scale the output.
I thought I'd tried that and it failed, but it looks to be just a problem of
stale statistics. Thanks Marius.

Hi All,
I'm using gdal_translate (version 1.6.3 on Ubuntu) with a scale factor
to stretch float values to 16-bit integer values. It works fine with tif
output, but with PNG it stretches the values to 8-bit:
gdal_translate -of PNG -scale 0 1550 0 65535 N2140615.txt N2140615.png

didn't you notice that...
Not really. I must have been blind.
Thanks for your hint. This works fine.

Herman,
didn't you notice that -32768 / 100 = -327.68 ~= -328 ... ;-) ? The issue is
that when doing rescaling, gdal_translate doesn't currently explicetly set
the source nodata value as the nodata value of the VRT source, so the pixels
whose value is the nodata value are just rescaled as other
Hi,
I am trying to scale the values in an Int16 raster band. Basically, I want to have them divided by 100. It looks to me that negative values are not scaled at all, whatever ranges I give to -scale. What am I doing wrong?

$ gdalinfo -mm infile.tif
