I have read several posts from last year regarding the poor image quality that is obtained from the GetThumbnail function. One of your developers had posted the following:
"You will get maximal possible quality of image when use GetThumbnail(1.0, 1.0).
After that I'd suggest to use Graphics.DrawImage(Image, RectangleF) for high quality
scaling with any interpolation mode you like." (See http://www.aspose.com/Community/Forums/22452/ShowPost.aspx)
Is that suggestion still the best way to get better quality images from the GetThumbnail function, or has a different (read better) solution been created?
