witwall / 1 - setting up RVM.sh

Created April 6, 2013 08:55

RVM and Bundler on Dreamhost, I can access https://gist.github.com/muffinista/3276350, so I copy it from the google cache

	#
	# Step One - Installing RVM
	#

	curl -L https://get.rvm.io \| bash -s stable --ruby

	# Then, install ruby 1.8.7 -- you need to basically match the same version of Ruby as Dreamhost

	rvm install ruby-1.8.7-p334

Here’s the code to replace images in PDFs, in Java and C#. It will replace the first image in the first page.

	PdfReader pdf = new PdfReader("in.pdf");
	PdfStamper stp = new PdfStamper(pdf, new FileOutputStream("c:\\out.pdf"));
	PdfWriter writer = stp.getWriter();
	Image img = Image.getInstance("image.png");
	PdfDictionary pg = pdf.getPageN(1);
	PdfDictionary res =
	(PdfDictionary)PdfReader.getPdfObject(pg.get(PdfName.RESOURCES));
	PdfDictionary xobj =
	(PdfDictionary)PdfReader.getPdfObject(res.get(PdfName.XOBJECT));

Automatic image deskew in Java http://anydoby.com/jblog/en/java/1990 Those who have to process scans should know how painful it is to manually deskew images. There are several approaches to do this deskewing automatically. The basis of all the methods is to identify lines following the same direction in a image and then by deviation from horizon…

	public double doIt(BufferedImage image) {
	final double skewRadians;
	BufferedImage black = new BufferedImage(image.getWidth(), image.getHeight(), BufferedImage.TYPE_BYTE_BINARY);
	final Graphics2D g = black.createGraphics();
	g.drawImage(image, 0, 0, null);
	g.dispose();

	skewRadians = findSkew(black);
	System.out.println(-57.295779513082320876798154814105 * skewRadians);
	return skewRadians;
