Hi I am using version 15, .Net libraries, c# to be exact. I want to be able to take images that are uploaded by my users, usually at 72 dpi, and convert them to 150 dpi, while retaining the same height/width. Can you point me in the right direction?

Thanks,
Allan Hensley

Hello,

Try to change the image resolution after loading it by using the MyRasterImage.XResolution and MyRasterImage.YResolution properties as follows:
+-----------+
RasterImage MyRasterImage = codecs.Load(FileName);
MyRasterImage.XResolution = 150;
MyRasterImage.YResolution = 150;
+-----------+

Please let me know if this helps.

Thanks,
Maen Badwan
