Gravity

Gravity is used to set the position of the object on the background; it uses the points of a compass: North, Northeast, East, Southeast, South, Southwest, west, Northwest and center

Finer positioning can be acheved using the -geometry operator

Image showing the gravity locations

$cmd =" convert -size 500x300 xc:white -font ../jd.ttf -pointsize 30 ".
" -draw \"gravity center fill black text 0,0 \'Center\' \" ".
" -draw \"gravity North fill black text 0,0 \'North\' \"  ".
" -draw \"gravity Northeast fill black text 0,0 \'Northeast\' \" ".
" -draw \"gravity East fill black text 0,0 \'East\' \" ".
" -draw \"gravity Southeast fill black text 0,0 \'Southeast\' \" ".
" -draw \"gravity South fill black text 0,0 \'South\' \" ".
" -draw \"gravity Southwest fill black text 0,0 \'Southwest\' \" ".
" -draw \"gravity West fill black text 0,0 \'West\' \" ".
" -draw \"gravity Northwest fill black text 0,0 \'Northwest\' \" ".
" -bordercolor black -border 1x1 gravity.jpg";
exec(" convert $cmd gravity.jpg" );

In this case I think a neater way of writting the code is using more php as below.



// Array of values
$arr = array("North", "Northeast", "East", "Southeast", "South", "Southwest", "West", "Northwest",
 "Center");
// Set $command
$command ="";
// Setup loop for the array
foreach ($arr as $value) {
// Create the individual draw commands and add them to the previous value of $command
$command .= " -draw \"gravity $value fill black text 0,0 $value \" " ;  }
// Create the image using php
exec(" convert -size 500x300 xc:white -font ../jd.ttf -pointsize 30 $command bordercolor black -border 1x1 gravity.jpg" );
