Tag Minimization
The start-tag is required for this element. The end-tag is optional, if your SGML declaration allows minimization.
Description
This element points to an external entity containing graphical image data.
Processing expectations
May be formatted inline or as a displayed block, depending on context. Render the image.
There are two ways to provide content for ImageData: EntityRef or FileRef. It is best to use only one of these methods, however, if multiple sources are provided, EntityRef will be used in favor of FileRef.
Parents
These elements contain ImageData: ImageObject.
Children
In some contexts, the following elements are allowed anywhere: BeginPage, IndexTerm.
Attributes
- Align
Align specifies the horizontal alignment of the image data on the page or within the element that frames it.
- Depth
Depth specifies the desired depth (vertical distance, at least in horizontal writing systems) of the image data.
- EntityRef
EntityRef identifies the general entity which points to the content of the image data.
- FileRef
FileRef specifies the name of the file which contains the content of the image data.
- Format
Format identifies the format of the image data. The Format must be a defined notation.
- Scale
Scale specifies integer representing a percentage scaling factor (retaining the relative dimensions of the original image data). If unspecified, the value 100 (100%) is assumed.
- Scalefit
If ScaleFit has the value 1 (true), then the image data is to be scaled (uniformly) to the specified width or depth. The default value of 0 (false) indicates that the image will not be scaled to fit (although it may still be scaled by the Scale attribute).
- SrcCredit
SrcCredit contains details about the source of the image data.
- Width
Width indicates the width of the graphic.
Examples
