All Known Implementing Classes:

PDFRenderTargetBuilder.PDFRenderTargetImpl

public interface PDFTarget
extends RenderTarget

Rendering target to PDF format.

This target is used by renderers objects to render a graph to PDF and uses the iText Java library.

The target give access to the PDFContentBype object from itext to draw items.

When this target is instanciated it uses property values defined in the PreviewProperties. Namely is uses MARGIN_LEFT, MARGIN_TOP, MARGIN_BOTTOM, MARGIN_RIGHT, LANDCAPE and PAGESIZE.

Method Detail

getContentByte

PdfContentByte getContentByte()

Returns the PDFContentBype instance of the PDFTarget. PDFContentByte offers a set of drawing functions which can be used by Renderer objects.

Returns:

a PDFContentBype object

getBaseFont

BaseFont getBaseFont(java.awt.Font font)

Get a the equivalent in iText of the Java font. Base fonts are either Type 1 fonts (PDF default's font) or valid system fonts. The first time a base font which is not a Type 1 is requested the system will register the system fonts in order to find the right font. This might take some time up to a minute.

If font can't be found in iText's default fonts or registered fonts it returns the default Helvetica font.

Parameters:

font - the reference Java font

Returns:

the iText BaseFont, or Helvetica is not found

float getMarginBottom()

Returns the margin at the bottom of the page.

Returns:

the bottom margin, in pixels

getMarginLeft

float getMarginLeft()

Returns the margin at the left of the page.

Returns:

the left margin, in pixels

getMarginRight

float getMarginRight()

Returns the margin at the right of the page.

Returns:

the right margin, in pixels

getMarginTop

float getMarginTop()

Returns the margin at the top of the page.

Returns:

the top margin, in pixels

isLandscape

Returns whether the orientation is in landscape or portrait.

Returns:

true if the orientation is landscape, false if portrait.
