Problem when using rotation arrows in Image Uploader v3

Original file is always uploaded unchanged, as rotation will cause its JPEG recompression.

We implemented it such way as source file can be changed noticeably after applying rotation. For example if we upload file with other then JPEG format (PNG, TIFF, and so on), we have to convert it to JPEG. On other side JPEG file after rotation has worse quality and doesn't preserve EXIF metadata (but upcoming Image Uploader 3.5 will resolve this issues).

To resolve this problem you can either rotate image on server side or try to upload not source file, but its thumbnail with FitMode=ActualSize. In following sample first thumbnail will have size of original image with applied rotation:

	<param name="UploadSourceFile" value="False">
	<param name="EnableRotate" value="True">

	<param name="UploadThumbnail1FitMode" value="ActualSize">
	<param name="UploadThumbnail1JpegQuality" value="70">

	<param name="UploadThumbnail2FitMode" value="fit">
	<param name="UploadThumbnail2Width" value="100">
	<param name="UploadThumbnail2Height" value="100">
	<param name="UploadThumbnail2JpegQuality" value="65">

This topic is out of date.

First of all you should use iuembed.js syntax now.

Also EnableRotate property was rename to

AllowRotate one.

iu.addParam("UploadSourceFile", "False");
iu.addParam("AllowRotate", "True");

iu.addParam("UploadThumbnail1FitMode", "ActualSize");
iu.addParam("UploadThumbnail1JpegQuality", "70");

iu.addParam("UploadThumbnail2FitMode", "fit");
iu.addParam("UploadThumbnail2Width", "100");
iu.addParam("UploadThumbnail2Height", "100");
iu.addParam("UploadThumbnail2JpegQuality", "65");
