imagebmp — Output a BMP image to browser or file

说明

imagebmp(GdImage $image, resource|string|null $file = 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 GdImage 对象。

file

文件保存的路径或者已打开的流资源（此方法返回后自动关闭该流资源），如果未设置或为 null，将会直接输出原始图象流。

注意:

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

成功时返回 true， 或者在失败时返回 false。

警告

如果 libgd 输出图像失败，函数会返回 true。

更新日志

版本 说明
8.0.0 image 现在需要 GdImage 实例；之前需要有效的 gd resource。
8.0.0 The type of compressed is bool now; formerly it was int.

示例

示例 #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');
?>
