Supported Output Formats

MapManager allows you to select range of image output formats supported by MapServer. The output format defines which renderer will be used to create the output of rendering operations. Not all of the formats are rendered directly in the Map Window.  Some formats as can be rendered directly to the screen or to a file while others are supported as output files only. The output format can be selected with the Image Type parameter of the Map Property Editor.

Each output format has a name (shown as the the Image Type parameter of the Map Property Editor) that defines the driver to use for rendering the map and a mime-type which is used by the CGI mapserver to specify the web content header accordingly. Further output format parameters are the image mode which define the layout of the image and the extension to specify the desired extension when saving the output file. These parameters cannot be set directly by MapManager, however it can be adjusted by manually editing the mapfile.

The following image modes are supported by MapServer:
 

• PC256 - Produced a pseudocoloured result with up to 256 colours in the palette (traditional MapServer mode).
• RGB - Render in 24 bit Red/Green/Blue mode. Supports all colours but does not support transparency.
• RGBA - Render in 32 bit Red/Green/Blue/Alpha mode. Supports all colours, and alpha based transparency. All features are rendered against an initially transparent background.
• BYTE - Render raw 8 bit pixel values (no presentation). Only works for RASTER layers (through GDAL) and WMS layers currently.
• INT16 - Render raw 16 bit signed pixel values (no presentation). Only works with RASTER layers (through GDAL) and WMS layers currently.
• FLOAT32 - Render raw 32 bit floating point pixel values (no presentation). Only works with RASTER layers (through GDAL) and WMS layers currently.
