Detailed Description

Object representing map window.

Definition at line 47 of file qgscomposermap.h.

Member Enumeration Documentation

Scaling modes used for the serial rendering (atlas)

Enumerator
Fixed 

The current scale of the map is used for each feature of the atlas

Predefined 

A scale is chosen from the predefined scales. The smallest scale from the list of scales where the atlas feature is fully visible is chosen.

See also
QgsAtlasComposition::setPredefinedScales.
Note
This mode is only valid for polygon or line atlas coverage layers
Auto 

The extent is adjusted so that each feature is fully visible. A margin is applied around the center

See also

Note
This mode is only valid for polygon or line atlas coverage layers

Member Function Documentation

QColor QgsComposerMap::annotationFontColor ( ) const

Get font color for grid annotations.

Deprecated:
use grid()->annotationFontColor() or grids() instead

Definition at line 1716 of file qgscomposermap.cpp.

double QgsComposerMap::annotationFrameDistance ( ) const
Deprecated:
use grid()->annotationFrameDistance() or grids() instead

Definition at line 1771 of file qgscomposermap.cpp.

void QgsComposerMap::assignFreeId ( )

Sets mId to a number not yet used in the composition.

mId is kept if it is not in use. Usually, this function is called before adding the composer map to the composition

Definition at line 2311 of file qgscomposermap.cpp.

bool QgsComposerMap::atlasDriven ( ) const
inline

Returns whether the map extent is set to follow the current atlas feature.

Returns
true if map will follow the current atlas feature.
See also
setAtlasDriven
atlasScalingMode

Definition at line 694 of file qgscomposermap.h.

bool QgsComposerMap::atlasFixedScale ( ) const

Returns true if the map uses a fixed scale when in atlas mode.

Deprecated:
since 2.4 Use atlasScalingMode() instead

Definition at line 2374 of file qgscomposermap.cpp.

double QgsComposerMap::atlasMargin ( const QgsComposerObject::PropertyValueType  valueType = QgsComposerObject::EvaluatedValue)

Returns the margin size (percentage) used when the map is in atlas mode.

Parameters
valueTypecontrols whether the returned value is the user specified atlas margin, or the current evaluated atlas margin (which may be affected by data driven atlas margin settings).
Returns
margin size in percentage to leave around the atlas feature's extent
Note
this is only used if atlasScalingMode() is Auto.
See also
atlasScalingMode
setAtlasMargin

Definition at line 2385 of file qgscomposermap.cpp.

AtlasScalingMode QgsComposerMap::atlasScalingMode ( ) const
inline

Returns the current atlas scaling mode.

This controls how the map's extents are calculated for the current atlas feature when an atlas composition is enabled.

Returns
the current scaling mode
Note
this parameter is only used if atlasDriven() is true
See also
setAtlasScalingMode
atlasDriven

Definition at line 721 of file qgscomposermap.h.

Definition at line 1078 of file qgscomposermap.cpp.

bool QgsComposerMap::cornerPointOnRotatedAndScaledRect ( double &  x,
double &  y,
double  width,

double QgsComposerMap::crossLength ( )
Deprecated:
use grid()->crossLength() or grids() instead

Definition at line 1896 of file qgscomposermap.cpp.

QgsRectangle * QgsComposerMap::currentMapExtent ( )

Returns a pointer to the current map extent, which is either the original user specified extent or the temporary atlas-driven feature extent depending on the current atlas state of the composition.

Both a const and non-const version are included.
