imagecreate — Create a new palette based image

Description

imagecreate(int $width, int $height): GdImage|false

imagecreate() returns an image identifier representing a blank image of specified size.

In general, we recommend the use of imagecreatetruecolor() instead of imagecreate() so that image processing occurs on the highest quality image possible. If you want to output a palette image, then imagetruecolortopalette() should be called immediately before saving the image with imagepng() or imagegif().

Parameters

width: The image width.
height: The image height.

Return Values

Returns an image object on success, false on errors.

Changelog

Version	Description
8.0.0	On success, this function returns a GDImage instance now; previously, a resource was returned.

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);
?>
