08-22-2008, 12:37 LeicaCoder Joined on 08-22-2008 Posts 1 RasterImage jpg Description I want to write a description into my jpeg file with a RasterImage and later read it out with a BitmapFrame (.net 3) I have tried adding to the comments property of the RasterImage, and turning on Comment saving in the RasterCodecs - but when I read the image back the comments field is empty (and thus presume that BitmapFirame would do no better). Is what I am trying to do possible? I know I can use a BitmapFrame to write out data to a Jpg file - but I also need to be able to do it from the leadtools components.    Report

The Comments is for Exif files (which can be JPEG compressed).  Are you saving the file format as Jpeg or ExifJpeg?  I'm pretty sure this functionality won't work for regular JPEGs. As for loading them back in, make sure that RasterCodecsOptions.Markers is set to true. Our v15 .NET help file has an example of how to do use these properties in the documentation for RasterImage.Comments. Greg Ross LEADTOOLS Technical Support    Report
