Harippriya Parameswaran updated PDFBOX-1571:
--------------------------------------------
Description:
I tried to create a image and superimpose on the PDF, the image looks fuzzy.
Also if i try to zoom the image created it looks fuzzy even for the first Zoom
Out.
I tried increasing the resolution this is increasing the image size while
superimposing and even looks more fuzzy with a huge image. Tried with the below
piece of code.
String fontFile = "Monika.ttf";
String text="Hello";
float fontSize = 20;
Font font = null;
try {
font = Font.createFont(Font.TRUETYPE_FONT,
Sample.class.getClassLoader()
.getResource(fontFile).openStream());
font = font.deriveFont(fontSize);
} catch (Exception e) {
throw new IOException("could not load TrueTypeFont for file: "
+ fontFile, e);
}
FontRenderContext fc = new FontRenderContext(null, true, true);
Rectangle2D bounds = font.getStringBounds(text, fc);
int width = (int) bounds.getWidth();
int height = (int) bounds.getHeight();
int maxWidth = 500;
int maxHeight = 50;
int minFontSize = 20;
while (width > (maxWidth - 2 * 5)
|| height > (maxHeight - 2 * 5)) {
if (fontSize <= minFontSize) {
break;
}
fontSize--;
font = font.deriveFont(fontSize);
bounds = font.getStringBounds(text, fc);
width = (int) bounds.getWidth();
height = (int) bounds.getHeight();
}
int paddingWidth = 5;
int paddingHeight = 5;
BufferedImage buffer = null;
PDDocument doc = new PDDocument();
PDPage page = new PDPage(new PDRectangle(width + 2 *
paddingWidth,
height + 2 * paddingHeight));
BufferedImage newBufferedImage = ImageIO.read(Sample.class
.getClassLoader()
.getResource(Sample.get("image.blue.background"))
.openStream());
PDJpeg newImage = new PDJpeg(doc, newBufferedImage);
PDFont pdffont = null;
try {
pdffont = PDTrueTypeFont.loadTTF(doc,
Sample.class.getClassLoader().getResource(fontFile).openStream());
} catch (Exception e) {
throw new IOException(
"could not load PDTrueTypeFont for
file: " + fontFile,
e);
}
PDPageContentStream stream = new PDPageContentStream(doc, page);
stream.drawImage(newImage, 0, 0);
stream.setNonStrokingColor(Color.BLACK);
stream.setStrokingColor(Color.BLACK);
stream.beginText();
stream.setFont(pdffont, fontSize);
stream.moveTextPositionByAmount(paddingWidth,
(float) (height / 2.5 + paddingHeight));
stream.drawString(text);
stream.endText();
stream.close();
buffer = page.convertToImage(BufferedImage.TYPE_INT_RGB,
94);
// Convert image image to PDXObjectImage
PDXObjectImage watermark = new PDJpeg(doc, buffer);
