NAME

       shp2img - create a map image from a mapfile

SYNOPSIS

       shp2img -m mapfile [-o image] [-e minx miny maxx maxy] [-s sizex sizey] [-l " layer1
               [layer2...]"] [-i format] [-all_debug n] [-map_debug n] [-layer_debug layername n]
               [-p n] [-c n] [-d layername datavalue]

DESCRIPTION

       shp2img creates a map image from a mapfile.  Output is either PNG or GIF depending on what
       version of the GD library is used. This is a useful utility to test your mapfile. You  can
       simply  provide  the  path  to  your mapfile and the name of an output image, and an image
       should be returned. If an image cannot be created  an  error  will  be  displayed  at  the
       command line that should refer to a line number in the mapfile.

OPTIONS

       -m mapfile
              Map file to operate on - required

       -i format
              Override the IMAGETYPE value to pick output format

       -o image
              Output filename (STDOUT if not provided)

       -e minx miny maxx maxy
              Extents to render

       -s sizex sizey
              Output image size

       -l layers
              Layers  to  enable - make sure they are quoted and space separated if more than one
              listed

       -all_debug n
              Set debug level for map and all layers

       -map_debug n
              Set map debug level

       -layer_debug layername n
              Set layer debug level

       -c n   Draw map n number of times

       -p n   Pause for n seconds after reading the map

       -d layername datavalue
              Change DATA value for layer

EXAMPLE

       Example #1

       shp2img -m vector_blank.map -o test.png

       Result:
              A file named 'test.png' is created, that you can drag into your browser to view.

       Example #2

       shp2img -m gmap75.map -o test2.png -map_debug 3

       Result:
              A file named 'test2.png' is created, and layer draw speeds are returned such as:

       msDrawRasterLayerLow(bathymetry): entering
       msDrawMap(): Layer 0 (bathymetry), 0.601s
       msDrawMap(): Layer 3 (drain_fn), 0.200s
       msDrawMap(): Layer 4 (drainage), 0.300s
       msDrawMap(): Layer 5 (prov_bound), 0.191s
       msDrawMap(): Layer 6 (fedlimit), 0.030s
       msDrawMap(): Layer 9 (popplace), 0.080s
       msDrawMap(): Drawing Label Cache, 0.300s
       msDrawMap() total time: 1.702s
       msSaveImage() total time: 0.040s

       Example #3

       shp2img -m gmap75.map -o test3.png -all_debug 3

       Result:
              A file named 'test3.png' is created, layer  draw  speeds  are  returned,  and  some
              warnings that index qix files are not found, such as:

       msLoadMap(): 0.671s
       msDrawRasterLayerLow(bathymetry): entering.
       msDrawGDAL(): src=72,417,3077,2308, dst=0,0,400,300
       msDrawGDAL(): red,green,blue,alpha bands = 1,0,0,0

       msSearchDiskTree(): Search returned no results. Unable to open spatial index

       safely ignore this message, otherwise check file names and permissions.
