ImageMagick Functions

Imagick::writeImages

Description:

bool Imagick::writeImages ( string $filename , bool $adjoin )

Writes an image or image sequence to the specified filename. If the filename parameter is NULL, the image is written to the filename set by Imagick::ReadImage() or Imagick::SetImageFilename().

Parameters:

filename

The file name of the image that is generated. The directory of the output image has to have permissions set so that PHP can write to it.

adjoin

If TRUE the output is a single image. If FALSE each frame is written as a separate image.

Return Values

Returns TRUE on success.

Text

<?

$font = "../../fonts/lokicola.ttf";
$fontsize = 100;
$fontcolor = "#ffff88";
$file = "ani_banner_1.gif";

$glow_radius = 3;
# Three glow colors
$glow = array( "#ff0000", "#ff8800", "#ffff00" );
$delay = 15;
# moves text down
$offset = 14;

# make a black pallete
$pallete = new Imagick;
$pallete->newimage(375,140, "#000000");
# set pallet format to gif
$pallete->setimageformat("gif");

# make a draw object with settings
$draw = new imagickdraw();
$draw->setgravity(imagick::GRAVITY_CENTER);
$draw->setfont("$font");
$draw->setfontsize($fontsize);

# clone pallete to make 3 blank frames
$frame_0 = $pallete->clone();
$frame_1 = $pallete->clone();
$frame_2 = $pallete->clone();

# put them in an array
$frames = array($frame_0, $frame_1, $frame_2);

# loop through frames, double glow radius each time, annotate
foreach( $frames as $frame)
 {
  # Loop through glow colors, annotate and blur
  foreach( $glow as $color)
  {
   $draw->setfillcolor("$color");
   $frame->annotateImage ( $draw,0 ,$offset, 0, $text );
   $frame->annotateImage ( $draw,0 ,$offset, 0, $text );
   $frame->BlurImage( $glow_radius, $glow_radius );
   $frame->setImageDelay("$delay");
  }
 # top layer of text over glow
 $draw->setfillcolor("$fontcolor");
 # center annotate on top of offset annotates
 $frame->annotateImage ( $draw,0 ,$offset, 0, $text );
 # double glow radius for next loop
 $glow_radius = $glow_radius*2;
 }

# add frames
$frame_0->addImage($frame_1);
$frame_0->addImage($frame_2);

# write animation
$frame_0->writeimages( "$file", TRUE);
# redirect browser to image
header("Location:$file");
