Besides JPEG the map images can now also be saved to PNG and GIF. Those newly supported image formats have great advantages over JPEG. GIF gives you christal clear images with sharp edges around text and borders. PNG combines the advantages of GIF and JPG, being a the best format for continuous data such as aireal photographs, satellite images or any color ramps, still keeping the file size small and the web site fast in loading the images over the web. The map tiling functionality of HTML ImageMapper can now also be used to produce maps for other GI systems and users by optionally creating world files (*.tfw, *.jgw,*.pgw, *.bpw).

The biggest enrichment of version 9.1 is the HTML ImageMapper API which enables developers to fully integrate maps produced with HTML ImageMapper into existing online applications and web sites or even develop new database driven mapping applications. The key feature is the new Export Database API which exports attribute tables enriched by map location information. Developers can now program a custom search on a database and then bring up the map with the object searched for highlighted.

HTML ImageMapper is now also available in Dutch and Chinese.
This reflects alta4's ambition to market this product internationally. The user interface is also available in English, German, French, Spanish, Swedish and Czech.

In building version 9.1 of HTML ImageMapper we have taken a pro-active stance and support the Word Wide Web Consortium's first recommendation for XHTML which became the official recommendation in 2000. XHTML successfully allows a vastly larger percentage of browsers or code parsers to properly parse the output map files produced by HTML ImageMapper. This means more people can see your site the way you meant for them to see it.

The web mapping pages that can be produced with HTML ImageMapper 9.1 have been enriched: the over view map is now equipped with a cross hair showing the actual position and zoom extent of the main map. The printable output has a nicer layout and includes the attributes of the selected object on the map. Now it is possible for the end user to search for something, find it on the map, highlight it and print it together with attribute information.

The user interface has become easier and smarter - automatically remembering settings made before and a new feature to synchronise the map with the current ArcMap document.

Last but not least alta4 improves customer service by delivering a automed check-for-updates feature in the new product. Whenever there's a new version or service pack available for download from the website www.alta4.com users will automatically be informed when using the software.
