drawEPP(): EPPL7 support is not available
Artikelaktionen
Error displayed when not using EPPL7 data.
This is a confusing error for users who are not even trying to view EPPL7 layers (EPPL7 is a raster format). The full error displayed may appear as follows:
msDrawRaster(): Unrecognized or unsupported image format ... drawEPP(): EPPL7 support is not available.
Explanation
When MapServer tries to draw a layer, it will attempt to use all of the drivers it knows about, and the EPPL7 driver is the very last driver it will try. This means that if a layer fails to draw for any reason, you will see this error message.
There are other possible instances when this error can appear however, here are a few:
- the server is returning either a ServiceException (which MapServer does not yet detect and parse into a reasonable error message) or it is returning an image in an unrecognized format ... for instance it is returning a GIF image and MapServer is not built to support GIF images.
- WMS servers often advertise multiple image formats but don't respect them in the getmap request.
