MosaicToNewRaster input parameter formatting help

HuyNgo — Thu, 13 Aug 2020 17:14:17 GMT

Running the MosaicToNewRaster tool works fine when I use the tool in ArcMap but it fails in .net when I use the exact same inputs. It leaves me to think that the way "input_rasters" is set up is wrong. Can anyone help me with correctly formatting my input_rasters string? This is typically happening only when I want to use more than 1 tiff file as input.

I have tried:

1) input_rasters = "'path\imgDirectory\img1.tiff';'path\imgDirectory\img2.tiff'"

2) input_rasters = "'path\imgDirectory\img1.tiff','path\imgDirectory\img2.tiff'"

3) I have tried inserting a string[] with the paths

but for some reason, I think the way I format my "input_rasters" is wrong. Because how can I get the Tool to work in ArcMap with the exact same parameters but not in c#?

The code and input works when trying to export as a tiff in c#, but will not work when exporting as a .jpg in c#. We want a .jpg because it is significantly smaller than a tiff file.

Hi,

I recommend exposing the parameter as a string and using inline variable substitution if you're using ModelBuilder or a similar approach if you're writing a Python script. For more information see Inline variable substitution—ArcGIS Pro | Documentation.

If you want to input multiple file names (strings) then you should consider defining the input parameter as a multi-value parameter. For more information see Setting script tool parameters—ArcGIS Pro | Documentation.

Thanks

Mike

Thanks for the response Michael, I ended up putting all of the MosaicToNewRaster code into a Python Script. while passing in my exact same parameters that I attempted to use in the c# version. It works as expected. So I technically didn't get this issue solved for anyone looking to leverage this tool in C# with multiple input raster. I recommend to just create a python scripts if you need to call the code from c#
