Gets a thumbnail representation of this page.
public RasterImage GetThumbnailImage()
Public Function GetThumbnailImage() As RasterImage
public RasterImage getThumbnailImage()
The thumbnail representation of this page.
This method uses the value set in DocumentImages.ThumbnailPixelSize to determine the size of the thumbnail image. The returned image data will have 24 bits per pixel.
This method works as follows (the "item" is a thumbnail image with the specified size):
If an item was found in the cache, it is returned right away. This is available if the document was created using the cache system. and LEADDocument.CacheOptions contains DocumentCacheOptions.PageThumbnailImage.
GetImage is used to create the thumbnail image.
If this document uses the cache system (LEADDocument.HasCache is true), then the RasterImage object is saved to the cache before it is returned. Next time this method is called, the image will be returned from the cache directly without loading it from the file or creating a new instance.
DocumentImages.GetThumbnailsGrid can be used to return the thumbnails of more than one page using a single call.
