So my new Japanese class has started (lousy classroom, good teacher, reasonable textbook, nice group of students, unbelievably gorgeous teacher’s assistant (I will never skip class…)), and, as expected, the teacher is pushing us to master hiragana quickly. I did that quite a while ago, so while everyone else is trying to learn it from scratch, I can focus on improving my handwriting.
One thing she suggested was a set of flash cards. I had mine with me, and mentioned that they were available for a quite reasonable price at Kinokuniya. Her response was along the lines of “yes, I know, but nobody ever buys optional study materials; do you think you could photocopy them so I can make handouts?”
I could, but that wouldn’t be nearly as much fun as making my own set. The first step was finding a decent kana font. Mac OS X ships with several Unicode fonts that include the full Japanese kana and kanji sets, but they didn’t meet my needs: looking good at display sizes, and clearly showing the boundaries between strokes. I found Adobe Ryo Display Standard. TextEdit seems to be a bit confused about its line-height, but I wasn’t planning to create the cards in that app anyway.
How to generate the card images? Perl, of course, with the PDF::API2::Lite module. I could have written a script that calculated the correct size of cards to fill the page, but I was feeling lazy, so I wrote a 12-line script to put one large character in the middle of a page, loaded the results into Preview, set the print format to 16-up with a page border, and printed to a new PDF file. Instant flash cards.
For many people, this would be sufficient, but one of the things sensei liked about the cards I had brought was the numbers and arrows that indicated the correct stroke order. There was no lazy way to do this, so I used Adobe Acrobat’s drawing and stamping tools. The stamping tool lets you quickly decorate a PDF file with images in many formats, so I just modified my previous script to create PDF files containing single numbers, and imported them into the stamp tool. The line-drawing tool let me make arrows, although I couldn’t figure out a simple way to set my own line-width and have it remembered (1pt was too thin after the 16-up, and 2pt had too-big arrowheads).
So why is this post titled “the cleansing power of Quartz”? Because the one-per-page annotated output from Acrobat was more than six times larger than the same file printed 16-up from Preview. Just printing the original file back to PDF shrank it by a factor of four, which, coincidentally, is almost exactly what you get when you run gzip on it…
The final results are here.
