      • hasPathOnStream

        private boolean hasPathOnStream
        Do we currently have an active path on the content stream, which has not been closed?

        We need this flag to avoid to clip twice if both the plaint applyer needs to clip, and we have some clipping. If at the end we try to clip with an empty path, then Acrobat Reader does not like that and draws nothing.

      • PdfBoxGraphics2D

        public PdfBoxGraphics2D​(org.apache.pdfbox.pdmodel.PDDocument document,
                                int pixelWidth,
                                int pixelHeight)
                         throws java.io.IOException
        Create a PDfBox Graphics2D. This size is used for the BBox of the XForm. So everything drawn outside the rectangle (0x0)-(pixelWidth,pixelHeight) will be clipped.

        Note: pixelWidth and pixelHeight only define the size of the coordinate space within this Graphics2D. They do not affect how big the XForm is finally displayed in the PDF.

        Parameters:
        document - The document the graphics should be used to create a XForm in.
        pixelWidth - the width in pixel of the drawing area.
        pixelHeight - the height in pixel of the drawing area.
        Throws:
        java.io.IOException - if something goes wrong with writing into the content stream of the PDDocument.

    • Method Detail

      • setColorMapper

        public void setColorMapper​(IPdfBoxGraphics2DColorMapper colorMapper)
        Set a new color mapper.
        Parameters:
        colorMapper - the color mapper which maps Color to PDColor.
      • setImageEncoder

        public void setImageEncoder​(IPdfBoxGraphics2DImageEncoder imageEncoder)
        Set a new image encoder
        Parameters:
        imageEncoder - the image encoder, which encodes an image as PDImageXForm.
      • setPaintApplier

        public void setPaintApplier​(IPdfBoxGraphics2DPaintApplier paintApplier)
        Set a new paint applier. You should always derive your custom paint applier from the IPdfBoxGraphics2DPaintApplier and just extend the paint mapping for custom paint.

        If the paint you map is a paint from a standard library, and you can implement the mapping using reflection please feel free to send a pull request to extend the default paint mapper.

        Parameters:
        paintApplier - the paint applier responsible for mapping the paint correctly
      • setDrawControl

        public void setDrawControl​(IPdfBoxGraphics2DDrawControl drawControl)
        Set a new draw control. This allows you to influence fill() and draw() operations. drawString() is only influence if the text is drawn as vector shape.
        Parameters:
        drawControl - the draw control
      • setFontTextDrawer

        public void setFontTextDrawer​(IPdfBoxGraphics2DFontTextDrawer fontTextDrawer)
        Set an optional text drawer. By default, all text is vectorized and drawn using vector shapes. To embed fonts into a PDF file it is necessary to have the underlying TTF file. The java.awt.Font class does not provide that. The FontTextDrawer must perform the java.awt.Font <=> PDFont mapping and also must perform the text layout. If it can not map the text or font correctly, the font drawing falls back to vectoring the text.
        Parameters:
        fontTextDrawer - The text drawer, which can draw text using fonts
      • getResources

        public org.apache.pdfbox.pdmodel.PDResources getResources()
        Sometimes you need to access the PDResources and add special resources to it for some stuff (e.g. patterns of embedded PDFs or simmilar). For that you need the PDResources associated with the XForm.

        It's identlical with getXFormObject().getResources(), with the difference beeing that you can access it while the Graphics2D is not yet disposed.

        Returns:
        the PDResources of the resulting XForm
      • getXFormObject

        public org.apache.pdfbox.pdmodel.graphics.form.PDFormXObject getXFormObject()
        *AFTER* you have disposed() this Graphics2D you can access the XForm
        Returns:
        the PDFormXObject which resulted in this graphics
      • gatherContext

        private java.lang.String gatherContext()
      • disposeDanglingChildGraphics

        public void disposeDanglingChildGraphics()
        Sometimes the users of create() don't correctly dispose() the child graphics they create. And you may not always be able to fix this uses, as it may be in some 3rdparty library. In this case this method can help you. It will cleanup all dangling child graphics. The child graphics can not be used after that. This method is a workaround for a buggy old code. You should only use it if you have to.

        Note: You can only call this method on the "main" graphics, not on a child created with create()

        public PdfBoxGraphics2D create()
        Creates a copy of this graphics object. Please call dispose() always on the copy after you have finished drawing with it.

        Never draw both in this copy and its parent graphics at the same time, as they all write to the same content stream. This will create a broken PDF content stream. You should get an IllegalStateException if you do so, but better just don't try.

        The copy allows you to have different transforms, paints, etc. than the parent graphics context without affecting the parent. You may also call create() on a copy, but always remember to call dispose() in reverse order.

        create in class java.awt.Graphics
        Returns:
        a copy of this Graphics.
