The following document outlines how to enable Flash output in MapServer. The library chosen to output SWF files is the Ming library. There are 2 possible output types:. A single movie containing the raster output for all the layers. To enable this, declare the following in the map file:.
A movie for every layer vector movies for vector layers and raster movies for raster layers. It results in a smaller SWF file. The default value is TRUE. Basically there will be an object called mapObj containing the height, width, extent, scale, number of layers, etc.
Here is an example in AS of the contents of this main movie:. This example is produced based on a mapfile with two layers defined in it. We create a layer class object containing useful information on a layer. The parameters are:. Note: All map parameters from MapServer are not exported at this time. The binary stream format allows the older players to skip non-supported contents.
Though original versions of SWF were limited to offer vector graphics and images, therefore new versions allow audio and video contents as well. Following are few basic datatypes of SWF file format. X-Y coordinates in SWF file format are stored as integers and measured in a unit called a twip.
The signed, and unsigned integer types of 8, 16, 32 and 64 bits are allowed in SWF file format. Little- endian byte order is used to store integer values. Though within bytes, the bit order is stored in big-endian. All integer values should be byte-aligned.
Several versions of SWF format have been evolved so far. After version 6, additional new changes are made at the ActionScript level. ActionScript 3. The user who plans to use latest versions, should aware to the use of ActionScript object model that Flash Player depicts. Table of Content.
