Rescale¶
This application is deprecated and will be removed in a future release.
Rescale the image between two given values.
Description¶
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.
Parameters¶
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).
Examples¶
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)
app.ExecuteAndWriteOutput()
