PHP Manual: imagebmp

Description

function imagebmp(GdImage $image, resource|string|null $file = null, bool $compressed = true): bool

Outputs or saves a BMP version of the given image.

Parameters

image: A GdImage object, returned by one of the image creation functions, such as imagecreatetruecolor().
file: The path or an open stream resource (which is automatically closed after this function returns) to save the file to. If not set or null, the raw image stream will be output directly.

Note:
null is invalid if the compressed arguments is not used.
compressed: Whether the BMP should be compressed with run-length encoding (RLE), or not.

Return Values

Returns true on success or false on failure.

Caution

However, if libgd fails to output the image, this function returns true.

Changelog

Version	Description
8.0.0	`image` expects a GdImage instance now; previously, a valid `gd` resource was expected.
8.0.0	The type of `compressed` is bool now; formerly it was int.

Examples

Example #1 Saving a BMP file

<?php
// Create a blank image and add some text
$im = imagecreatetruecolor(120, 20);
$text_color = imagecolorallocate($im, 233, 14, 91);

imagestring($im, 1, 5, 5,  'BMP with PHP', $text_color);

// Save the image
imagebmp($im, 'php.bmp');
