Hi everyone,

Does anyone know how to do Scale Convolutions, Invert Pixel Values and Invert Y Coordinates on ImageJ?  I used NIH Image before and I can go to Options -> Preferences and check on Scale Convolutions, Invert Pixel Values and Invert Y Coordinates boxes.

Thanks
Thamonwan

Scale Convolutions:
     Convert the image to 32-bit (float) before
     using Process>Filters>Convolve.

Invert Pixel Values:
     Check "Use Inverting Lookup Table" in
     Edit>Options>Images (only works with 8-bit images).

Invert Y Coordinates:
     Check "Invert Y Coordinates" in
     Analyze>Set Measurements.
