Aurigma Upload Suite 8.0.67
Converter..::.AutoReduceDimensions Property HTML5/Flash Uploader ASP.NET
Gets or sets a value specifying what to do if the browser does not allow creating resized copies of specified size.
Assembly: Aurigma.ImageUploaderFlash (in Aurigma.ImageUploaderFlash.dll)
Not all browsers are memory friendly enough to generate large images. For example, Safari on iOS cannot create image larger than 5Mpix (very old iPhones - not more than 2MPix). Firefox and IE are limited by 32Mpix.
This parameter is used to define a strategy, the uploader should use to handle this situation. If you set true, you say "give me as a large image as you are able to generate". However if it is not acceptable (for example, a user places an order for printing), you can set false and the uploader will handle it as if it is a non-image file.
It makes sense setting it to false only if you set the fallback option in the Mode property, for example "*=Thumbnail;SourceFile". This way you will receive an original file if the uploader failed to create a resized copy.
