Learning Pdftk by examples
2007 | Filed Under PDF, Tips, How-to, Software | Leave a Comment
Pdftk is a simple tool for doing everyday things with PDF documents. It allows you to manipulate PDF easily and freely. It does not require Acrobat, and it runs on Windows, Linux, Mac OS X, FreeBSD and Solaris.
Examples:
Merge PDF Documents
Merge Two or More PDFs into a New Document
pdftk 1.pdf 2.pdf 3.pdf cat output 123.pdf
or (Using Handles):
pdftk A=1.pdf B=2.pdf cat A B output 12.pdf
or (Using Wildcards):
pdftk *.pdf cat output combined.pdf
“cat” is short for concatenate. Pdftk doesn’t retain bookmarks, but it does keep hyperlinks to both destinations within the PDF and to external files or Web sites. Where some other applications point to the wrong destinations for hyperlinks, the links in PDFs combined using pdftk managed to hit each link target perfectly.
Split PDF Pages into a New Document
pdftk A=one.pdf B=two.pdf cat A1-7 B1-5 A8 output combined.pdf
Remove Pages from PDF Documents
Remove ‘page 13′ from in1.pdf to create out1.pdf
pdftk in.pdf cat 1-12 14-end output out1.pdf
or (Using Handles):
pdftk A=in1.pdf cat A1-12 A14-end output out1.pdf

Scan to PDF directly using gscan2pdf in Ubuntu
2007 | Filed Under PDF, Ubuntu, Linux, Software | 2 Comments
I like to backup my important documents or briefs into my computer in PDF file type. But in my experiment using a scan in Ubuntu is not easy as in Windows System.
The gscan2pdf is a GUI program to directly create a multipage PDF from a scan. It should work on almost any Linux/BSD system.
How to install the gscan2pdf in Ubuntu or Debian-based system
First you need to add the following line to your /etc/apt/sources.list file:
deb http://gscan2pdf.sourceforge.net/download/debian binary/
Then you need to update the source list with the following command:
apt-get update
Now you can install gscan2pdf with the following command:
apt-get install gscan2pdf
I use a simple scan Canon CanoScan N655U. I test gscan2pdf to scan a color and a normal A4 form pages with different scan model and dips. I become the following results:
At first, we should know what does dpi mean and how much dpi is enough.

爬高上低
2007 | Filed Under Story of Sissi | Leave a Comment
Sissi 又长大了，她现在特别喜欢爬高上低，沙发，床，椅子都是她练习的好场所。
一天，她自己搬了个小板凳放在客厅的茶几旁，然后先上了小板凳，接着又麻利的爬上了茶几，最后她站在茶几上高兴的来回走动。大人想过来扶着她，她还不愿意呢。
今天，Sissi 午觉醒来后，爬上了床上叠好的被子，然后对奶奶说，高！奶奶问她，Sissi， 你怕不怕？ Sissi 就连忙爬了下来，然后搂着奶奶的脖子说，怕！怕！

How to mount or burn a .bin Image
2007 | Filed Under Ubuntu, How-to, Linux | Leave a Comment
I choose a easy way. First change the .bin/.cue file to a standard .iso image. Then use the normal methods to mount or burn the image.
You can also use bchunk to convert bin/cue CD-images to iso Image.
bchunk movie.bin movie.cue movie
Then you can mount the iso image use:
mount -t iso9660 -o loop [isofile] [mountpoint]
To burn a CD, I use the GnomeBaker or Bracero CD Burner.
