Example 2 with ImageData

use of com.itextpdf.io.image.ImageData in project pdf-editor by Pdf-Creator.

the class PDFDocument method addRectangleWithFormulaItem.

public void addRectangleWithFormulaItem(FormulaItem formulaItem) throws IOException {
    PdfCanvas canvas = new PdfCanvas(currentPage);
    Rectangle rect = new Rectangle(formulaItem.getX(), formulaItem.getY(), formulaItem.getW(), formulaItem.getW());
    canvas.setStrokeColor(formulaItem.getRectangleStrokeColor()).setFillColor(formulaItem.getRectangleStrokeColor()).rectangle(rect).fill().stroke();
    // very strange method
    TeXFormula tf = new TeXFormula(formulaItem.getFormula());
    TeXIcon ti = tf.createTeXIcon(TeXConstants.STYLE_DISPLAY, formulaItem.getFontSize());
    BufferedImage bimg = new BufferedImage(ti.getIconWidth(), ti.getIconHeight(), BufferedImage.TYPE_4BYTE_ABGR);
    // -- painting the formula --
    Graphics2D g2d = bimg.createGraphics();
    g2d.setColor(Color.white);
    g2d.fillRect(0, 0, ti.getIconWidth(), ti.getIconHeight());
    JLabel jl = new JLabel();
    jl.setForeground(new Color(0, 0, 0));
    ti.paintIcon(jl, g2d, 0, 0);
    // --------------------------
    // -- adding it to pdf --
    ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
    ImageIO.write(bimg, "png", byteArrayOutputStream);
    ImageData data = ImageDataFactory.create(byteArrayOutputStream.toByteArray());
    Image image = new Image(data);
    image.setFixedPosition(formulaItem.getX(), formulaItem.getY());
    image.scaleAbsolute(formulaItem.getW(), formulaItem.getH());
    new Canvas(canvas, rect).add(image);
}

Example 3 with ImageData

use of com.itextpdf.io.image.ImageData in project i7j-pdfsweep by itext.

the class PdfCleanUpProcessor method cleanInlineImage.

private void cleanInlineImage() {
    ImageRenderInfo encounteredImage = ((PdfCleanUpEventListener) getEventListener()).getEncounteredImage();
    PdfCleanUpFilter.FilterResult<ImageData> imageFilterResult = filter.filterImage(encounteredImage);
    ImageData filteredImage;
    if (imageFilterResult.isModified()) {
        filteredImage = imageFilterResult.getFilterResult();
    } else {
        filteredImage = ImageDataFactory.create(encounteredImage.getImage().getImageBytes());
    }
    if (filteredImage != null) {
        Boolean imageMaskFlag = encounteredImage.getImage().getPdfObject().getAsBool(PdfName.ImageMask);
        if (imageMaskFlag != null && (boolean) imageMaskFlag) {
            filteredImage.makeMask();
        }
        float[] ctm = pollNotAppliedCtm();
        writeNotAppliedGsParams(false, false);
        openNotWrittenTags();
        getCanvas().addImageWithTransformationMatrix(filteredImage, ctm[0], ctm[1], ctm[2], ctm[3], ctm[4], ctm[5], true);
    }
// TODO
// PdfCanvas doesn't have a method that writes inline image using pdf stream, and only have method which
// accepts Image as parameter. That's why we can't write image just as it was in original file, we convert it to Image.
// IMPORTANT: If writing of pdf stream of not changed inline image will be implemented, don't forget to ensure that
// inline image color space is present in new resources if necessary.
