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.
