[mapserver-dev] v6 beta 4 Cairo PDF and raster

[Brent Fraser]

Thomas,

I'm using the test map file and data:

MAP

NAME TEST
STATUS ON
SIZE 400 300
EXTENT 0.5 0.5 399.5 299.5
IMAGECOLOR 255 255 255
SHAPEPATH "../gdal"
IMAGETYPE CAIRO_PDF

OUTPUTFORMAT
    NAME 'CAIRO_PDF'
    DRIVER CAIRO/PDF
    EXTENSION "pdf"
END

LAYER
   NAME grey
   TYPE raster
   STATUS default
#  OPACITY 50
   DATA data/grey.tif
END

END # of map file


When OPACITY is used, the raster data is not included in the PDF.  
Commenting out OPACITY results in a PDF with a raster.

Best Regards,
Brent Fraser
