This application is deprecated and will be removed in a future release.

Rescale the image between two given values.


This application scales the given image pixel intensity between two given values. By default min (resp. max) value is set to 0 (resp. 255). Input minimum and maximum values is automatically computed for all image bands.

This application has several output images and supports “multi-writing”. Instead of computing and writing each image independently, the streamed image blocks are written in a synchronous way for each output. The output images will be computed strip by strip, using the available RAM to compute the strip size, and a user defined streaming mode can be specified using the streaming extended filenames (type, mode and value). Note that multi-writing can be disabled using the multi-write extended filename option: &multiwrite=false, in this case the output images will be written one by one. Note that multi-writing is not supported for MPI writers.


Input Image -in image Mandatory
The image to scale.

Output Image -out image [dtype] Mandatory
The rescaled image filename.

Output min value -outmin float Default value: 0
Minimum value of the output image.

Output max value -outmax float Default value: 255
Maximum value of the output image.

Available RAM (MB) -ram int Default value: 256
Available memory for processing (in MB).


From the command-line:

otbcli_Rescale -in QB_Toulouse_Ortho_PAN.tif -out rescaledImage.png uchar -outmin 0 -outmax 255

From Python:

import otbApplication

app = otbApplication.Registry.CreateApplication("Rescale")

app.SetParameterString("in", "QB_Toulouse_Ortho_PAN.tif")
app.SetParameterString("out", "rescaledImage.png")
app.SetParameterOutputImagePixelType("out", 1)
app.SetParameterFloat("outmin", 0)
app.SetParameterFloat("outmax", 255)
