HP41's LCD Characters TTF File available Message #1 Posted by Vieira, Luiz C. (Brazil) on 24 July 2002, 12:48 p.m.
Hi;
I intend to turn it into an article, but I believe I can count on you , guys, to give me a feedback.
In 1995 I wrote a book about both HP41 and HP48 (Portuguese only) and it dealt with the transition "from the HP41 to the HP48" (in Portuguese, that's exactly the title: "Da HP41 para a HP48"). I was known about Wickes' "HP41/HP48 Transitions" when I was writing mine, and in fact I did not have the pleasure yet to read it. I have the first two volumes of the HP48 Insights, and I believe Transitions may also be a great reading.
At that time, I used to think how good would it be if I had TTF that could give me the LCD's characters for the HP41. In my book I used some BMP from transferred HP48 screen to the computer. But the LCD's characters in the HP41 are something more than BMP imageses.
After finishing the book, I spent some time researching, and found Corel DRAW! as the, at least for me, available tool to generate the TTF.
I spent one month, about one hour a day, Monday to Friday, and I could finally generate a TTF file with all characters in the 41's LCD, another with all possible keycodes for all HP calculators (recently updated to accept HP49's new characters), other three ones with all three-size HP48 characters, one with the inverted smallest HP48's font (softkey menus) and one with voyagers' LCD characters. Only one problem: I created them all as standard set, not symbol char sets, and some problems appeared.
Well, three fellows from here (contributors) have test-driven the HP41 LCD character font, and one of them alerted me about its size (somewhat tall). I fixed it and also converted the hole font to symbol font (in fact, I had to redraw the pattern and save all characters again; it took me a few couple of hours, but definitely a lot less time then when I created the files).
I asked Dave if he could host the HP41 TTF file (it is somewhat small, no need to zip it) and he accepted. If you want to download it, go here for the HP41 font, and if you want first to have a look at it, download this PDF demonstration.
Please, 41 users and maniacs (as I am), send me any feedback about this TTF (like it or not, let me know). I'd gladly improve it, if needed.
The Voyager Charset is also something to see. If you want to try it, send me an e-mail. If people ask to, I'll ask Dave to host it too.
Hope you enjoy.
Best regards.
