imagebmp — Output a BMP image to browser or file

说明

imagebmp ( resource $image [, mixed $to = NULL [, bool $compressed = TRUE ]] ) : bool

Outputs or saves a BMP version of the given image.

参数

image: 由图象创建函数(例如imagecreatetruecolor())返回的图象资源。
to: 文件保存的路径，如果未设置或为 NULL，将会直接输出原始图象流。

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.

返回值

Caution

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

范例

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');

// Free up memory
imagedestroy($im);
