Create an ImageRenderInfo

Parameters:

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

stream - image stream object

colorSpaceDictionary - the color space dictionary from resources which are associated with the image

isInline - defines if the encountered image was inline

Method Detail

getImage

public PdfImageXObject getImage()

Gets an image wrapped in ImageXObject. You can:

• get image bytes with PdfImageXObject.getImageBytes(boolean), these image bytes represent native image, i.e you can write these bytes to disk and get just an usual image;
• obtain PdfStream object which contains image dictionary with PdfObjectWrapper.getPdfObject() method;
• convert image to BufferedImage with PdfImageXObject.getBufferedImage();

getStartPoint

public Vector getStartPoint()

Returns:

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

getImageCtm

public Matrix getImageCtm()

Returns:

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

getArea

public float getArea()

Returns:

the size of the image, in User space units

isInline

public boolean isInline()

Returns:

true if image was inlined in original stream.

getColorSpaceDictionary

public PdfDictionary getColorSpaceDictionary()

Returns:

the color space dictionary from resources which are associated with the image
