Positioning images within text
To position the InlineGraphicElement within the text, you use the following properties:
float property of the InlineGraphicElement class
clearFloats property of the FlowElement
The float property controls the placement of the graphic and the text around it. The clearFloats property controls
the placement of the paragraph elements relative to the float.
To control the location of an image within a text element, you use the float property. The following example adds an
image to a paragraph and aligns it to the left so the text wraps around the right:
Images in a flow are a good thing. For example, here is a
float. It should show on the left: Don't you agree? Another sentence here. Another
sentence here. Another sentence here. Another sentence here. Another sentence here. Another
sentence here. Another sentence here. Another sentence here.
Valid values for the float property are “left”, “right”, “start”, “end”, and “none”. The Float class defines these
constants. The default value is “none”.
The clearFloats property is useful in cases where you want to adjust the starting position of subsequent paragraphs
that would normally wrap around the image. For example, assume that you have an image that is larger than the first
paragraph. To be sure the second paragraph starts after the image, set the clearFloats property.
The following example uses an image that is taller than the text in the first paragraph. To get the second paragraph to
start after the image in the text block, this example sets the clearFloats property on the second paragraph to “end”.
