Hi All
I am trying to convert a grey-scale raster (TIFF file) to one where the pixel colour is based on a scale of the Band 0 value that is specified for each pixel, where green is used as the lowest value and then scales to red for the highest value. The only transformer that I found where I can set the colour is the GradedColorizer.
I first used the RasterCellCoercer to get to the Ban 0 value (_band{0}.value) for each pixel and then uses in the the GradedColoriser. Once this transformer finishes its operations on the data, it gets sent to an ImageRasteriser to recreate a raster, which is then sent to a TIFF writer. The workbench file is attached here: . A test image can be found here: .
The workbench however fails at the ImageRasteriser, stating INVALID_VECTOR_GEOMETRY_COLOR as reason.
I must add that my understanding on raster bands are rather limited. I have also tried other transformers to keep the image as an image, and work with the Alpha band, but this seems to require more knowledge than I have.
Can anyone perhaps tell me what I am doing wrong here? I have had quite a look at the other questions on the knowledge base but was not able to find anything quite similar (and probably as basic as I am attempting to do).
Any help would be appreciated.
