mxText

Extends mxShape to implement a text shape. To change vertical text from bottom to top to top to bottom, the following code can be used:

mxText.prototype.ieVerticalFilter = 'progid:DXImageTransform.Microsoft.BasicImage(rotation=1)';
mxText.prototype.verticalTextDegree = 90;

mxText.prototype.getVerticalOffset = function(offset)
{
  return new mxPoint(-offset.y, offset.x);
};

Parameters

value	String that represents the text to be displayed. This is stored in <value>.

fontStyle	Specifies the font style. Default is 0. This is stored in <fontStyle>.
spacing	Integer that specifies the global spacing. Default is 2. This is stored in <spacing>.
spacingTop	Integer that specifies the top spacing. Default is 0. The sum of the spacing and this is stored in <spacingTop>.

spacingBottom	Integer that specifies the bottom spacing. Default is 0.The sum of the spacing and this is stored in <spacingBottom>.
spacingLeft	Integer that specifies the left spacing. Default is 0. The sum of the spacing and this is stored in <spacingLeft>.

wrap	Specifies if word-wrapping should be enabled. Default is false. This is stored in <wrap>.
clipped	Specifies if the label should be clipped. Default is false. This is stored in <clipped>.
overflow	Value of the overflow style. Default is ‘visible’.

Variables

replaceLinefeeds

mxText.prototype.replaceLinefeeds

Specifies if linefeeds in HTML labels should be replaced with BR tags. Default is true. This is also used in mxImageExport to export the label.

ieVerticalFilter

mxText.prototype.ieVerticalFilter

Holds the filter definition for vertical text in IE. Default is progid:DXImageTransform.Microsoft.BasicImage(rotation=3).

verticalTextDegree

mxText.prototype.verticalTextDegree

Specifies the degree to be used for vertical text. Default is -90.

forceIgnoreStringSize

mxText.prototype.forceIgnoreStringSize

Specifies if the string size should always be ignored. Default is false. This can be used to improve rendering speed in slow browsers. This can be used if all labels are smaller than the vertex width. String sizes are ignored by default for labels which are left aligned with no background and border or if the overflow is set to fill.
