Struct Transform 

pub struct Transform {
    pub off_x: Option<Emu>,
    pub off_y: Option<Emu>,
    pub ext_cx: Option<Emu>,
    pub ext_cy: Option<Emu>,
    pub rot: Option<i32>,
    pub flip_h: bool,
    pub flip_v: bool,
}

仿射变换。

Fields

off_x: Option<Emu>

off_y: Option<Emu>

ext_cx: Option<Emu>

ext_cy: Option<Emu>

rot: Option<i32>

顺时针旋转（60000 分之一度）。

flip_h: bool

水平翻转。

flip_v: bool

垂直翻转。

Implementations

impl Transform

pub fn write_xml(&self, w: &mut XmlWriter)

写一段 XML。

元素结构（OOXML）

<a:xfrm rot="..." flipH="1" flipV="1">     ← 属性可省略
  <a:off x="..." y="..."/>                 ← 可选
  <a:ext cx="..." cy="..."/>               ← 可选
</a:xfrm>

错误模式

• 早期版本曾把属性错误地写成嵌套的 <a:xfrm/> + </a:xfrm>，导致 PowerPoint 报 “Invalid OOXML”。本方法已合并到同一个外层 <a:xfrm> 开始标签上。

pub fn is_empty(&self) -> bool

是否所有字段都为空。

Trait Implementations

impl Clone for Transform

fn clone(&self) -> Transform

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Transform

impl Debug for Transform

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Transform

fn default() -> Transform

Returns the “default value” for a type.

impl Eq for Transform

impl PartialEq for Transform

fn eq(&self, other: &Transform) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
