"After testing many different image manipulation
DLLs, it was amazing to see the differences. ImgWriter
was rock solid, generating 10,000 test images in
1 minute 25 seconds with little overhead and no
leaks. The other components either bogged down
the server or leaked memory through the DLLHost.exe
process. ImgWriter clearly stood way ahead of the
pack. I'll be buying it today!"

SoftArtisans ImgWriter contains two server-side COM components:
- SAImageGen offers image manipulation functionality,
such as image resizing, image cropping, and writing text
on an image. SAImgGen lets you create thumbnails from larger
images or add watermarks to existing images. It exposes low-level
methods for precise image manipulation. The component can
also be used to construct new images, such as charts, labels,
or banners. SAImageGen supports the nine most common image
formats, including jpeg, bmp, emf, png, and tiff. It can
read and save images to and from a file on disk, and in-memory
byte array, or a database blob. It can also write an image
to the browser. SAImageGen's more advanced functionality
includes writing text on images, cropping images, merging
two images, and creating images with gradient background.
Some image formats vary in size depending on image quality.
The component allows you to modify both quality and size
for such formats. Transparency and dithering can also be
controlled.
- SAImageCollection offers an in-memory-cached collection
of images for high-speed access. It is intended to run at
application scope, so it is thread safe (it supports the "Both" threading
model) and supports concurrent read access to images in the
collection. The component allows images to be shared across
a web application, conserving precious server resources,
and accessed very quickly, improving your users' experience.
Images can be added to the cache from a file on disk or from
an ADO Recordset.
