ImageEditor 是 gd 函数的包装器。之前它只在 yii-application 上下文中工作，现在您可以在任何应用程序中使用此包。
安装
- Composer 包：
wapmorgan/image-editor[1] - 存档：
https://github.com/wapmorgan/ImageEditor/archive/master.zip
如何开始：从现有文件创建或创建一个空区域
$image = ImageEditor::createFromFile($filename); // or $image = ImageEditor::createWithSize($width, $height); // or $image = ImageEditor::createFromResource(imagecreatetruecolor(90, 90));
属性
- width - 图像宽度
- height - 图像高度
- resource - 图像的原始 gd-resource（您可以将其直接传递给 image-gd 函数）
操作
调整大小 && 缩放（不裁剪图像）
可以最小化和最大化图像:
- zoomWidthTo(int $size) - 按比例更改图像宽度为
$size - zoomHeightTo(int $size) - 按比例更改图像高度为
$size
只能最小化图像:
- decreaseWidthTo(int $size) - 按比例减小图像宽度到
$size，如果需要的话 - decreaseHeightTo(int $size) - 按比例减小图像高度到
$size，如果需要的话 - decreaseTo(int $size) - 按比例减小较大的边到
$size，如果需要的话
可以完成您要求的所有操作:
- resize(int $width, int $height) - 将图像调整大小为
$widthX$height
裁剪（可以裁剪图像）
- crop($x, $y, $x2, $y2) - 裁剪图像的一个矩形部分
- decreaseSide($side, int $size) - 从特定边删除图像的一部分。例如，如果 $side=top 且 $size=100，则顶部将删除 100px。
旋转 && 镜像
- rotate($angle, $bgColor = 0) - 旋转图像。
True等于 90°，False等于 -90°。 - horizontalFlip() - 水平翻转图像。
- verticalFlip() - 垂直翻转图像。
处理
- appendImageTo($side, ImageEditor $appendix, int $modifiers) - 将图像（
$appendix）附加到当前图像的$side（《top|bottom|left|right》） - placeImageAt($x, $y, ImageEditor $image) - 在
$xX$y处将图像放置在当前图像之上。 - placeImageAtCenter(ImageEditor $image) - 将图像放置在当前图像的中心。
保存
- save($filename, $format, $quality) - 将图像保存到磁盘。可能的
$format值：jpeg、png、gif、wbmp。质量是一个介于 0（最差）和 100（最佳）之间的整数。
