PDFViewCtrlSetupThumbnails Method |
Enables or disables thumbnail view features.
Thumbnail view is used before a PDF page is fully rendered. If runtime
thumb view generation is enabled, PDFViewCtrl generates thumbnail views
at runtime. If a PDF file already contains the thumbnail views, runtime
thumb view generation can be turned off, which is more efficient.
If runtime thumb view generation is enabled, the thumbMaxSideLength
will be used as a reference to calculate the thumbnail resolution.

Parameters
- use_embedded_thumbs
- Type: SystemBoolean
Enables or disables using thumbnails embedded in the PDF
document as a preview of the rendered page. This flag is
currently ignored, but functionality may be added to support
embedded thumbnails in the future.

Enables or disables generating thumbnails at runtime.
Default is enabled.
- use_persistent_cache
- Type: SystemBoolean
[Missing <param name="use_persistent_cache"/> documentation for "M:pdftron.PDF.PDFViewCtrl.SetupThumbnails(System.Boolean,System.Boolean,System.Boolean,System.Int32,System.UInt32,System.Double)"]
- thumb_max_side_length
- Type: SystemInt32
The maximum size, in pixels, of a dimension of generated
thumbnails.
- max_abs_cache_size
- Type: SystemUInt32
The maximum absolute size, in bytes, the thumbnail cache file may take up
on disk.
- max_perc_cache_size
- Type: SystemDouble
The maximum percentage of free disk space, in the range 0 - 1.0, the thumbnail
cache file may take up.
