Working with Images

Being an image-aware software, Image Uploader has some imaging capabilities. It can perform the following image-related tasks:

  • Display previews
  • Resize images
  • Compress images using JPEG algorithm
  • Rotate images (both manually by the user and automatically based on EXIF information)
  • Draw watermarks on thumbnails
  • Handle EXIF and IPTC metadata

It recognizes the following file formats as images:

  • JPEG
  • TIFF (ActiveX only)
  • BMP
  • GIF
  • PNG
  • PSD (ActiveX only)
  • WBMP (ActiveX only)

Image Uploader can load files of these formats and display previews for them, however, it can save the image only into the single format - JPEG. So if you create a thumbnail for some image file (say, GIF), or create a rotated version, it will be saved to JPEG format. See more details in the Resizing and Rotating Images topic.

If you need more advanced imaging capabilities than Image Uploader presents, you can send only the original files and perform all the imaging operations on the server side (for example, using Aurigma Graphics Mill both ActiveX and .NET versions or whatever other image processing tools which are available on your server platform). Image Uploader retrieves all necessary information to do it. The Server Imaging Sample demo application illustrates this approach.
