Do not use PNG8 as the tile format if you are caching a multiband image service. It is recommended to use other tile formats such as PNG24/ PNG32 /JPEG/Mixed.
Redefine the tile format that can support caching a multiband image service.
- Right-click the message and click Show Advanced Cache Settings page.
- Change the tile format from PNG8 to any of the other tile formats listed.
Once you address the issue, click the Analyze button on the Service Editor dialog box to reanalyze the service.
When publishing a mosaic dataset as an image service, the mosaic dataset will be analyzed. This analysis is performed at a higher level and will compare the resolution corresponding to minimum and maximum cache scales to the maximum visible cell size of the mosaic dataset.
If you do not redefine the scales, blank tiles will be generated.
