IMAGECREATETRUECOLOR(3) 1 IMAGECREATETRUECOLOR(3)imagecreatetruecolor - Create a new true color imageSYNOPSIS
resource imagecreatetruecolor (int $width, int $height)
DESCRIPTION imagecreatetruecolor(3) returns an image identifier representing a black image of the specified size.
Depending on your PHP and GD versions this function is defined or not. With PHP 4.0.6 through 4.1.x this function always exists if the GD
module is loaded, but calling it without GD2 being installed PHP will issue a fatal error and exit. With PHP 4.2.x this behaviour is dif-
ferent in issuing a warning instead of an error. Other versions only define this function, if the correct GD version is installed.
PARAMETERS
o $width
- Image width.
o $height
- Image height.
RETURN VALUES
Returns an image resource identifier on success, FALSE on errors.
EXAMPLES
Example #1
Creating a new GD image stream and outputting an image.
<?php
header ('Content-Type: image/png');
$im = @imagecreatetruecolor(120, 20)
or die('Cannot Initialize new GD image stream');
$text_color = imagecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 5, 5, 'A Simple Text String', $text_color);
imagepng($im);
imagedestroy($im);
?>
The above example will output something similar to:[NOT DISPLAYABLE MEDIA]Output of example : Creating a new GD image stream and
outputting an image.
NOTES
Note
This function requires GD 2.0.1 or later (2.0.28 or later is recommended).

IMAGECREATE(3) 1 IMAGECREATE(3)imagecreate - Create a new palette based imageSYNOPSIS
resource imagecreate (int $width, int $height)
DESCRIPTION imagecreate(3) returns an image identifier representing a blank image of specified size.
In general, we recommend the use of imagecreatetruecolor(3) instead of imagecreate(3) so that image processing occurs on the highest qual-
ity image possible. If you want to output a palette image, then imagetruecolortopalette(3) should be called immediately before saving the
image with imagepng(3) or imagegif(3).
PARAMETERS
o $width
- The image width.
o $height
- The image height.
RETURN VALUES
Returns an image resource identifier on success, FALSE on errors.
EXAMPLES
Example #1
Creating a new GD image stream and outputting an image.
<?php
header("Content-Type: image/png");
$im = @imagecreate(110, 20)
or die("Cannot Initialize new GD image stream");
$background_color = imagecolorallocate($im, 0, 0, 0);
$text_color = imagecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 5, 5, "A Simple Text String", $text_color);
imagepng($im);
imagedestroy($im);
?>
The above example will output something similar to:[NOT DISPLAYABLE MEDIA]Output of example : Creating a new GD image stream and
