Examples with ImageRenderInfo com.itextpdf.kernel.pdf.canvas.parser.data.ImageRenderInfo used on opensource projects

Example 1 with ImageRenderInfo

use of com.itextpdf.kernel.pdf.canvas.parser.data.ImageRenderInfo 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.
