Re: [mapserver-users] Photo Viewer
I do this by faking a WMS-service, with the pixel size of the scan as
map boundaries, and using an arbitrary EPSG. It's primitive, but it
works and I use it a lot, especially for large serieses of scans.
See:
http://mapserver.sara.nl/atlas/georef.html
Left the unreferenced scan, right the referenced maps, both zoomable
independently. With a little elementary math, you can even align both
maps (the sync buttons). You can even use it in QGIS or any other
WMS-enabled program, e.g. to set reference points for warping or
designing vector art work. Comments appreciated.

(file: utils.inc)
?php
function getSizeRaster($data) {
//Compute size of raster file $data in array $arr
return ($ar);
}
function createMapFromData($title,$epsg,$parms,$data)
$oMap = ms_newMapObj();
$oMap-setProjection(init=epsg:$epsg);
$oMap-setMetaData(wms_title,$title);
$oMap-setMetaData(wms_srs,epsg:$epsg);
$oMap-setMetadata(wms_contactperson,Jan Hartmann);
$oMap-setMetadata(wms_contactorganization,University of
Amsterdam);
$oMap-setMetadata(wms_contactelectronicmailaddress,j.l.h.hartm...@uva.nl);
$oMap-setMetadata(wms_enable_request,*);
$pwd = http://mapserver.sara.nl/; . $_SERVER[SERVER_NAME];
$pwd = $pwd . $_SERVER[PHP_SELF];
if ($parms) $pwd = $pwd . ?$parms;
$oMap-setMetadata(wms_onlineresource,$pwd);
$l = ms_newLayerObj($oMap);
$l-set(name,$title);
$l-setProjection(init=epsg:$epsg);
$l-setMetadata(wms_title,$title);
$l-setMetadata(wms_srs,epsg:$epsg);
$l-set(status,MS_DEFAULT);
$l-set(type,MS_LAYER_RASTER);
$l-set(data,$data);
$ar = getSizeRaster($data);
$oMap-setExtent($ar[0],$ar[1],$ar[2],$ar[3]);
$oMap-setMetadata(wms_extent,$ar[0] $ar[1] $ar[2] $ar[3]);
$l-setMetadata(wms_extent,$ar[0] $ar[1] $ar[2] $ar[3]);
$oMap-setSize(600,600 * (($ar[3]-$ar[1]) / ($ar[2] - $ar[0])));
return($oMap);
}
function dispatchMap($oMap) {
$request = ms_newowsrequestobj();
$request-loadparams();
ms_ioinstallstdouttobuffer();
$oMap-owsdispatch($request);
$contenttype = ms_iostripstdoutbuffercontenttype();
if ($contenttype == text/xml) {
header(Content-type: application/xml);
$buffer = ms_iogetstdoutbufferstring();
echo $buffer;
} else {
header(Content-type:$contenttype);
ms_iogetStdoutBufferBytes();
}
ms_ioresethandlers();
}
?
The simplest WMS-service would be a PHP-script like
?php
require(utils.inc);
$fn = path to scan-file;
$oMap = createMapFromData(WMS_title,28992,,$fn);
dispatchMap($oMap);
?
The WMS-service would just be:
mywms.php
When you have a series of numbered scans in subdirectories, you could do:
?php
require(utils.inc);
$base = base directory of scans;
$subdir = $_REQUEST[subdir];
$nr = $_REQUEST[nr];
$path = $base/$subdir/scan_$nr.tif;
$oMap = createMapFromData(scan,28992,subdir=$subdirnr=$nr,$path);
dispatchMap($oMap);
?
And accessl each scan as a WMS service like:
mywms.php?subdir=subdirnr=nr
