Method Detail

createForXObject

public static ImageRenderInfo createForXObject(Matrix ctm,
                               PdfIndirectReference ref,
                               PdfDictionary colorSpaceDictionary)

Create an ImageRenderInfo object based on an XObject (this is the most common way of including an image in PDF)

Parameters:

ctm - the coordinate transformation matrix at the time the image is rendered

ref - a reference to the image XObject

Returns:

the ImageRenderInfo representing the rendered XObject

Since:

5.0.1

createForEmbeddedImage

protected static ImageRenderInfo createForEmbeddedImage(Matrix ctm,
                                     InlineImageInfo inlineImageInfo,
                                     PdfDictionary colorSpaceDictionary)

Create an ImageRenderInfo object based on inline image data. This is nowhere near completely thought through and really just acts as a placeholder.

Parameters:

ctm - the coordinate transformation matrix at the time the image is rendered

imageObject - the image object representing the inline image

Returns:

the ImageRenderInfo representing the rendered embedded image

Since:

5.0.1

getImage

public PdfImageObject getImage()
                        throws IOException

Gets an object containing the image dictionary and bytes.

Returns:

an object containing the image dictionary and byte[]

Throws:

IOException

Since:

5.0.2

getStartPoint

public Vector getStartPoint()

Returns:

a vector in User space representing the start point of the xobject

getImageCTM

public Matrix getImageCTM()

Returns:

The coordinate transformation matrix active when this image was rendered. Coordinates are in User space.

Since:

5.0.3

getArea

public float getArea()

Returns:

the size of the image, in User space units

Since:

5.0.3

getRef

public PdfIndirectReference getRef()

Returns:

an indirect reference to the image

Since:

5.0.2
