JPEG quality for the specified upload thumbnail.

Syntax

Get/Set Value in Runtime
JavaScript CopyCode imageCopy Code
getImageUploader("ImageUploaderID").setUploadThumbnailJpegQuality(Index, value);
value = getImageUploader("ImageUploaderID").getUploadThumbnailJpegQuality(Index);
Parameters
Index

A non-negative integer that specifies an index of the upload thumbnail (one-based). It should not exceed UploadThumbnailCount - 1 . If extra upload thumbnails are required, use the UploadThumbnailAdd method to add them.

Property Value

A positive integer value that specifies a JPEG quality for the specified upload thumbnail in range from 0 (the worst quality) to 100 (the best quality).

Remarks

You can reduce a thumbnail file size by specifying the lower quality.

If the fit mode is ActualSize, the image is recompressed (and therefore this property is applicable) only when the original image is not JPEG.

Image Uploader can generate multiple thumbnails per one file sent to the server. To configure sizes of thumbnails and other parameters, you can manipulate a list of upload thumbnail settings. It can be done two ways:

  1. Use UploadThumbnailNXXX parameters, where N is a number in range from 1 to 3.
  2. Use the UploadThumbnailAdd method in JavaScript to add extra thumbnail sizes, and UploadThumbnailXXX properties to change specific settings.

First method is simpler, however it allows to upload not more than 3 thumbnails per one file. The second one does not have any limitation on the number of thumbnails.

To get an upload thumbnail on the server use the UploadThumbnailX HTTP POST field, where X is an index of the upload thumbnail.

NoteNote

The index of upload thumbnail list is zero-based. However by default upload thumbnail with zero index is disabled (its fit mode is Off).
