SetThumbnailRenderingThreshold(int)
For any pages that are not forced to include thumbnails this function adjusts whether we should include them depending on the complexity of the page. This can be used to include fewer or more thumbnails as required by the use case. In particular reducing this value will tend to increase the number of page thumbnails included and vice versa.
Declaration
public ViewerOptimizedOptions SetThumbnailRenderingThreshold(int threshold)
Parameters
Type | Name | Description |
---|---|---|
int | threshold | A number from 0 (include all thumbnails) to 100 (include only the first thumbnail) representing the complexity at which SaveViewerOptimized would include the thumbnail. The default value is 50. |
Returns
Type | Description |
---|---|
