In ArcMap Desktop 10.2.2, I have a Erdas Imagine, please see the picture, its NoData is displayed as blue. I can use "Split Raster" tool(Opened by clicking: menu Geoprocessing >> ArcToolBox >> Data Management Tools >> Raster >> Raster Processing >> Split Raster) to split this map into tiles. however, in the splited tiles, the backgrond is black, (what I expect is background is blue).

How can I specify a color that nodata pixel will be rendered ?

I guess that the color may be related to the "NoData value" option when I runing "Split Raster", however, I searched all web but can not find any clues how to set this option.

enter image description here


At last, we use the plugin "gridSplitter" in qgis to solve this. basically, the "gridSplitter" plugin use gdalwarp to cut a tile from img, it can specify two argument: srcnodata and dstnodata, in my img, set srcnodata to 0, and dstnodata 100 to set background to gray. if blue, set dstnodata to "0 0 255".
