Set Visio Shape's XForm, Line and Fill Data
Setting XForm Data
The XForm element is part of the Microsoft Visio XML schema. XForm specifies a shapes position, for example width, height, rotation and whether the shape has been flipped. The XForm property, exposed by the Shape class, supports the Aspose.Diagram.XForm object. The XForm property can be used to retrieve or update a shape’s XForm data. The code examples in this article change the PinX (X-coordinate) and PinY (Y-coordinate) XForm values to move the shapes on the page.
The process for updating XForm data is:
- Load a diagram.# Find a particular shape.# Update the shape’s XForm data.
- Save the diagram.
The code snippet below shows how to update a shape’s XForm data. The code looks for a shape names process, with the shape ID 1, and sets its X and Y coordinates to 5.
Set Visio Shape’s Line Data
Shapes can be formatted in several ways. This article shows how to specify a line’s attributes.
Microsoft Visio lets users format lines in various ways. Aspose.Diagram for .NET supports:
- Weight: a line’s thickness.
- Color: set shape’s line color.
- Line Color Transparency: set shape’s line color transparency in percentage.
- Pattern: defines whether the line is solid, dashed or has another pattern.
- Rounding: the radius of corners.
- Beginning and ending arrows: specified whether the line has arrows.
- Beginning and ending arrow sizes: set the arrow sizes.
- Cap: the rounding of the line ends.
Change the line color, weight, dash type, transparency, rounding, arrow type and arrow size of a shape’s border
Line Data Programming Sample
The following piece of code updates the line data of shape.
Set Visio Shape’s Fill Data
Shapes can be formatted in several ways. This topic describes how to specify a shape’s fill. Microsoft Office Visio lets users format fills in various ways. The Fill class of the Aspose.Diagram for .NET API supports setting:
- Background and foreground colors.
- Fill patterns.
Setting Fill Values
Fill Data Programming Sample
The following code snippet updates a shape’s fill data. The code looks for a shape named rectangle, with the shape ID 1, and sets the fill background and foreground colors.
Retrieve Inherited Fill Data of a Visio Shape
The Visio shapes can inherit the parent style and the master shape. Developers may get or set the inherit fill data of a Visio shape. The InheritFill property, exposed by the Shape class, contains the fill formatting values for the shape inherit by the parent style and the master shape.
Retrieve Inherited Fill Data Programming Sample
The following code snippet retrieves the inherited fill data of the shape. Please check this sample code:
