When I invoke the addColorBarLower method below, the pdfContentByte is
typically generated by code like:
PdfReader cardReader = new PdfReader(myFile.getAbsolutePath());
//PdfReader cardReader = new PdfReader(new
RandomAccessFileOrArray(cardTempFile.getAbsolutePath()), null);
PdfImportedPage importedPage = copy.getImportedPage(cardReader, i);
PdfCopy.PageStamp cardStamp = copy.createPageStamp(importedPage);
PdfContentByte over = cardStamp.getOverContent();
The code works fine as is to add a color bar with some text to a page in an
existing PDF, but if I comment the first instantiation of the cardReader
object and uncomment the second, I do not see the color bar. Am I doing
something wrong?
public static void addColorBarLower(PdfContentByte pdfContentByte, String
mixId, int currentQuantity, int totalQuantity, int currentPage, int
pageCount, Rectangle pageSize) throws IOException, DocumentException {
float colorBarHeight = pageSize.getHeight() / 2;
PdfTemplate template = pdfContentByte.createTemplate(colorBarHeight,
COLOR_BAR_WIDTH); //Inverted because of rotation
String slug = mixId + " Set " + currentQuantity + " of " +
totalQuantity + " Page " + currentPage + " of " + pageCount;
Rectangle rectangle = new Rectangle(0, 0, colorBarHeight,
COLOR_BAR_WIDTH);
if (currentQuantity % 2 == 0) { //Even set
rectangle.setBackgroundColor(COLOR_BAR_LOWER_EVEN);
} else { //Odd set
rectangle.setBackgroundColor(COLOR_BAR_LOWER_ODD);
}
template.rectangle(rectangle);
template.beginText();
template.setFontAndSize(BaseFont.createFont(COLOR_BAR_FONT,
COLOR_BAR_ENCODING, false), COLOR_BAR_FONT_SIZE);
template.showTextAligned(PdfTemplate.ALIGN_LEFT, slug.toUpperCase(),
COLOR_BAR_INSET, COLOR_BAR_INSET, 0);
template.endText();
Image colorBar = Image.getInstance(template);
colorBar.setRotationDegrees(COLOR_BAR_DEG_ROTATE);
colorBar.setAbsolutePosition(0, 0);
pdfContentByte.addImage(colorBar);
}
