We have a custom extension that renders the display using IDisplay::startDrawing. Our extension supports both win32 and x64. .ecw rasters appear solid black when run in an x64 process, but render correctly in a win32 process. Is this a known issue? If so, is it documented anywhere? (so we can refer our customers to something.) http://desktop.arcgis.com/en/arcmap/10.3/analyze/executing-tools/64bit-background.htm doesn't specifically mention .ecw/ERDAS.
Hi, which version are you using? I did see some 10.3 bugs of Raster tools failing when running as 64bit with ecw files, which seem to be fixed in 10.4 build 5305, like BUG-000086778 at BUG-000086778: The Workspace to Raster Catalog tool returns an erro. Would you please try it on 10.4 to see if it works? If still not, it might be a bug, then could you please log it with Esri Tech Support with a reproducible sample?
