Placeholders

The following classes represent placeholder shapes. A placeholder most commonly appears on a slide, but also appears on a slide layout and a slide master. The role of a master placeholder and layout placeholder differs from that of a slide placeholder and these roles are reflected in the distinct classes for each.

There are a larger variety of slide placeholders to accomodate their more complex and varied behaviors.

MasterPlaceholder objects

class pptx.shapes.placeholder.MasterPlaceholder[源代码]

Placeholder shape on a slide master.

property auto_shape_type

Enumeration value identifying the type of this auto shape, like MSO_SHAPE.ROUNDED_RECTANGLE. Raises ValueError if this shape is not an auto shape.

click_action

ActionSetting instance providing access to click behaviors.

Click behaviors are hyperlink-like behaviors including jumping to a hyperlink (web page) or to another slide in the presentation. The click action is that defined on the overall shape, not a run of text within the shape. An ActionSetting object is always returned, even when no click behavior is defined on the shape.

property element

lxml element for this shape, e.g. a CT_Shape instance.

Note that manipulating this element improperly can produce an invalid presentation file. Make sure you know what you’re doing if you use this to change the underlying XML.

fill

FillFormat instance for this shape, providing access to fill properties such as fill color.

property has_text_frame

True if this shape can contain text. Always True for an AutoShape.

property height

Read/write. Integer distance between top and bottom extents of shape in EMUs

property is_placeholder

True if this shape is a placeholder. A shape is a placeholder if it has a <p:ph> element.

property left

Read/write. Integer distance of the left edge of this shape from the left edge of the slide, in English Metric Units (EMU)

line

LineFormat instance for this shape, providing access to line properties such as line color.

property name

Name of this shape, e.g. ‘Picture 7’

property placeholder_format

A _PlaceholderFormat object providing access to placeholder-specific properties such as placeholder type. Raises ValueError on access if the shape is not a placeholder.

property rotation

Read/write float. Degrees of clockwise rotation. Negative values can be assigned to indicate counter-clockwise rotation, e.g. assigning -45.0 will change setting to 315.0.

shadow

ShadowFormat object providing access to shadow for this shape.

A ShadowFormat object is always returned, even when no shadow is explicitly defined on this shape (i.e. it inherits its shadow behavior).

property shape_id

Read-only positive integer identifying this shape.

The id of a shape is unique among all shapes on a slide.

property text

Read/write. Unicode (str in Python 3) representation of shape text.

The returned string will contain a newline character ("\n") separating each paragraph and a vertical-tab ("\v") character for each line break (soft carriage return) in the shape’s text.

Assignment to text replaces all text previously contained in the shape, along with any paragraph or font formatting applied to it. A newline character ("\n") in the assigned text causes a new paragraph to be started. A vertical-tab ("\v") character in the assigned text causes a line-break (soft carriage-return) to be inserted. (The vertical-tab character appears in clipboard text copied from PowerPoint as its encoding of line-breaks.)

Either bytes (Python 2 str) or unicode (Python 3 str) can be assigned. Bytes can be 7-bit ASCII or UTF-8 encoded 8-bit bytes. Bytes values are converted to unicode assuming UTF-8 encoding (which also works for ASCII).

property text_frame

TextFrame instance for this shape.

Contains the text of the shape and provides access to text formatting properties.

property top

Read/write. Integer distance of the top edge of this shape from the top edge of the slide, in English Metric Units (EMU)

property width

Read/write. Integer distance between left and right extents of shape in EMUs

LayoutPlaceholder objects

class pptx.shapes.placeholder.LayoutPlaceholder[源代码]

Note that manipulating this element improperly can produce an invalid presentation file. Make sure you know what you’re doing if you use this to change the underlying XML.

property has_chart

True if this graphic frame contains a chart object. False otherwise.

When True, the chart object can be accessed using the .chart property.

property shape_type

Optional member of MSO_SHAPE_TYPE identifying the type of this shape.

Possible values are MSO_SHAPE_TYPE.CHART, MSO_SHAPE_TYPE.TABLE, MSO_SHAPE_TYPE.EMBEDDED_OLE_OBJECT, MSO_SHAPE_TYPE.LINKED_OLE_OBJECT.

PlaceholderPicture objects

class pptx.shapes.placeholder.PlaceholderPicture[源代码]

Placeholder shape populated with a picture.

property auto_shape_type

Member of MSO_SHAPE indicating masking shape.

A picture can be masked by any of the so-called “auto-shapes” available in PowerPoint, such as an ellipse or triangle. When a picture is masked by a shape, the shape assumes the same dimensions as the picture and the portion of the picture outside the shape boundaries does not appear. Note the default value for a newly-inserted picture is MSO_AUTO_SHAPE_TYPE.RECTANGLE, which performs no cropping because the extents of the rectangle exactly correspond to the extents of the picture.

The available shapes correspond to the members of MSO_AUTO_SHAPE_TYPE.

The return value can also be None, indicating the picture either has no geometry (not expected) or has custom geometry, like a freeform shape. A picture with no geometry will have no visible representation on the slide, although it can be selected. This is because without geometry, there is no “inside-the-shape” for it to appear in.

click_action

ActionSetting instance providing access to click behaviors.

Click behaviors are hyperlink-like behaviors including jumping to a hyperlink (web page) or to another slide in the presentation. The click action is that defined on the overall shape, not a run of text within the shape. An ActionSetting object is always returned, even when no click behavior is defined on the shape.

float representing relative portion cropped from left of shape.

Read/write. 1.0 represents 100%. A negative value extends the side beyond the image boundary.

property crop_right

float representing relative portion cropped from right of shape.

Read/write. 1.0 represents 100%.

property crop_top

float representing relative portion cropped from shape top.

Read/write. 1.0 represents 100%.

Note that manipulating this element improperly can produce an invalid presentation file. Make sure you know what you’re doing if you use this to change the underlying XML.

property height

The effective height of this placeholder shape; its directly-applied height if it has one, otherwise the height of its parent layout placeholder.
