ogrtindex(1) General Commands Manual ogrtindex(1)NAME
ogrtindex - ogrtindex creates a tileindex
SYNOPSIS
ogrtindex [-lnum n]... [-lname name]... [-f output_format]
[-write_absolute_path] [-skip_different_projection]
output_dataset src_dataset...
DESCRIPTION
The ogrtindex program can be used to create a tileindex - a file containing a list of the identities of a bunch of other files along with
there spatial extents. This is primarily intended to be used with MapServer for tiled access to layers using the OGR connection type.
-lnum n:
Add layer number 'n' from each source file in the tile index.
-lname name:
Add the layer named 'name' from each source file in the tile index.
-f output_format:
Select an output format name. The default is to create a shapefile.
-tileindex field_name:
The name to use for the dataset name. Defaults to LOCATION.
-write_absolute_path:
Filenames are written with absolute paths
-skip_different_projection:
Only layers with same projection ref as layers already inserted in the tileindex will be inserted.
If no -lnum or -lname arguments are given it is assumed that all layers in source datasets should be added to the tile index as independent
records.
If the tile index already exists it will be appended to, otherwise it will be created.
It is a flaw of the current ogrtindex program that no attempt is made to copy the coordinate system definition from the source datasets to
the tile index (as is expected by MapServer when PROJECTION AUTO is in use).
EXAMPLE
This example would create a shapefile (tindex.shp) containing a tile index of the BL2000_LINK layers in all the NTF files in the wrk
directory:
% ogrtindex tindex.shp wrk/*.NTF

IMAGESETTILE(3) 1 IMAGESETTILE(3)imagesettile - Set the tile image for fillingSYNOPSIS
bool imagesettile (resource $image, resource $tile)
DESCRIPTION imagesettile(3) sets the tile image to be used by all region filling functions (such as imagefill(3) and imagefilledpolygon(3)) when fill-
ing with the special color IMG_COLOR_TILED.
A tile is an image used to fill an area with a repeated pattern. Any GD image can be used as a tile, and by setting the transparent color
index of the tile image with imagecolortransparent(3), a tile allows certain parts of the underlying area to shine through can be created.
Note
You need not take special action when you are finished with a tile, but if you destroy the tile image, you must not use the
IMG_COLOR_TILED color until you have set a new tile image!
PARAMETERS
o $
image -An image resource, returned by one of the image creation functions, such as imagecreatetruecolor(3).
o $tile
- The image resource to be used as a tile.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
imagesettile(3) example
<?php
// Load an external image
$zend = imagecreatefromgif('./zend.gif');
// Create a 200x200 image
$im = imagecreatetruecolor(200, 200);
// Set the tile
imagesettile($im, $zend);
// Make the image repeat
imagefilledrectangle($im, 0, 0, 199, 199, IMG_COLOR_TILED);
// Output image to the browser
header('Content-Type: image/png');
imagepng($im);
imagedestroy($im);
imagedestroy($zend);
?>
