conjure（MSL 脚本）
使用示例 • 选项一览 • Magick Scripting Language (MSL)
conjure 程序让你能够从用 Magick Scripting Language（MSL）编写的脚本执行自定义图像处理任务。MSL 基于 XML，由带属性的动作语句构成。动作包括读取图像、处理图像、获取图像属性、写出图像等。属性是修改动作行为的 key/value 对。有关如何组织 conjure 命令的建议，请参阅命令行处理，或参阅下面的命令使用示例。
使用示例
为说明 conjure 命令的实用性和易用性，这里列举几个示例。首先，给出一个简单的 conjure 命令：
magick conjure -dimensions 400x400 msl:incantation.msl
上面使用的 MSL 脚本 incantation.msl 如下：
<?xml version="1.0" encoding="UTF-8"?>
<image>
<read filename="image.gif" />
<get width="base-width" height="base-height" />
<resize geometry="%[dimensions]" />
<get width="resize-width" height="resize-height" />
<print output="Image sized from %[base-width]x%[base-height] to %[resize-width]x%[resize-height].\n" />
<write filename="image.png" />
</image>
在这个示例中，一个家庭在假期里待在家中，但在朋友看来他们去了加勒比海的美丽海滩：
<?xml version="1.0" encoding="UTF-8"?>
<group>
<image id="family">
<read filename="family.gif"/>
<resize geometry="300x300"/>
</image>
<image id="palm-trees">
<read filename="palm-trees.gif"/>
<resize geometry="300x100"/>
</image>
<image>
<read filename="beach.jpg"/>
<composite image="family" geometry="+30+40"/>
<composite image="palm-trees" geometry="+320+90"/>
</image>
<write filename="family-vacation.png"/>
</group>
这里以像素为单位显示特定字体和点大小的文本宽度。
<?xml version="1.0" encoding="UTF-8"?>
<image>
<query-font-metrics text="ImageMagick" font="helvetica" pointsize="48" />
<print output="Text width is %[msl:font-metrics.width] pixels.\n" />
</image>
query-font-metrics 标签支持以下属性：
msl:font-metrics.pixels_per_em.x
msl:font-metrics.pixels_per_em.y
msl:font-metrics.ascent
msl:font-metrics.descent
msl:font-metrics.width
msl:font-metrics.height
msl:font-metrics.max_advance
msl:font-metrics.bounds.x1
msl:font-metrics.bounds.y1
msl:font-metrics.bounds.x2
msl:font-metrics.bounds.y2
msl:font-metrics.origin.x
msl:font-metrics.origin.y
MSL 支持 ImageMagick 的 Perl API 中讨论的大多数方法和属性。
此外，MSL 支持带单个 indexes 元素的 swap 元素。
