Public Property ImageFormat As ArcGISDynamicMapServiceLayer.RestImageFormat | |
| C# | |
|---|---|
public ArcGISDynamicMapServiceLayer.RestImageFormat ImageFormat {get; set;} | |
Remarks
The default image format is PNG24. There are four ArcGISDynamicMapServiceLayer.RestImageFormat Enumeration values that can be used for the ImageFormat Property, they are:
- PNG24
- JPG
- PNG8
- PNG32
The background color for an ArcGISDynamicMapServiceLayer will always be transparent when the ImageFormat is set to use a lossless data compression such as PNG. JPG is considered a lossy data compression and as such will not show the background of the layer to be transparent, meaning it will not drape well over other background layers. Theoretical information related to these compression types can be found for the following topics:
