Exporting a PNG

Load or generate a Raster data set into a Map window
Find the Raster data set you want to export in the Layers list and select it.
Right click it and select Export to PNG...
Enter the desired export resolution, or leave the values as default, and click Export.

Note: Specify a higher resolution to output a higher quality image. Images are upscaled using bi-linear interpolation.
Specify the location and name of the PNG file you'd like to save and click OK.
