Highlights of the available features are: multiple scale types; anti-aliasing of lines; color-gradient fills; support for GIF, JPEG, and PNG formats; and support for multiple Y axes. Many plot types are supported, such as pie-charts, lineplots, bar plots, impulse plots, polar plots, error plots, contour plots, matrix plots, gantt charts, and many more. The pro-version also contains extensive 1D and 2D barcode support. The documentation is extensive and is over 700 pages.
There are many photo-gallery programs available. Zoph is different, as it concentrates on the management of large collection of photos instead of just showing them on the Web. It can store a lot of information about your photos, including the regular EXIF info, photographer, location, title, description, rating, and the people in the photo. Photos can appear in multiple albums and categories. Additional features include search, slideshows, lightboxes, email, access privileges, and multiple languages.
Pigalle (PIcture GALLEry) is a slick Web based photo album written in PHP 5. It makes it easy to create and maintain photo albums via an intuitive interface, as users need only upload their files to a server and let the program generate thumbnails for them. Visitors can choose their preferred image resolution and images will be generated on the fly. These generated images are cached and all meta-information such as album descriptions, image information, and user settings are stored in a database. A back-end administration interface helps to manage the files, edit the descriptions, and so on, making it very easy and convenient.
ImaginView Photo Gallery Class is a class for creating photo galleries. It features automatic thumbnail generation/caching, is recursive, and supports JPEG and PNG (and GIF, if your GDlib has GIF support). It's template-based, making customization easy, and it uses footers/headers in txt/html/php format.
Dynamic Copyright It! is a tool that allows you to add copyright notices on-the-fly directly onto your images without any fussing around in image editors. It's easy to integrate with other scripts that will allow you to edit the copyright text of images throughout an entire Web site without manually editing each one. The copyright text, font size, and color of the notice can be customized.
