Aurigma Upload Suite 8.0.67
ImageEditor..::.CropRatio Property HTML5/Flash Uploader ASP.NET
Gets or sets an aspect ratio of the crop rectangle.
Assembly: Aurigma.ImageUploaderFlash (in Aurigma.ImageUploaderFlash.dll)
Crop ratio is width-to-height, thus, property value should be greater than 1 to get landscape orientation and lesser than 1 to get portrait. For example, if you set 0.75 as the property value, it will result in portrait with 3:4 aspect ratio.
Another possible value is orig. It means that the uploader will preserve the original aspect ratio.
You can restrict users from changing the aspect ratio by adding "; fixed" to the value. For example, the following value: "4:3; fixed" sets the 4:3 aspect ratio, which cannot be chaged by users.
