I have a simple map that I exported from ArcGIS to Illustrator. The base layer is a hillshade raster. I made sure no layer in the ArcGIS document has any transparency to prevent rasterizing of unneeded layers. The graphic I want to create follows the shape of our regional county boundary. In other words, I want the border of our region to be the shape/extent of the map and the background to be transparent. The problem is that the area outside of the regional boundary is symbolized as white when I want it to be transparent. In Illustrator I can't isolate the hillshade image alone without the white background.
- Made Sure that the background color of the map in ArcGIS is sett to null.
- Tested the "Clip Output to Graphics Extent" option when exporting from ArcGIS.
- Made sure the "Document Raster Effects Settings" for "Background" is set to "Transparent".
- Tried treating a clipping mask around the boundary layer to "mask" away the white back ground (this didn't work - might be inexperienced mistake).
- Exported the hillshade layer independently to both Illustrator and PNG format with NO success.
See Attached for example.
Any help making this white background would be awesome. Thank you in advance.
