I'm always excited when some new technological technique or toy catches my attention. I've had a few in recent weeks (Lilypond and Blender), but the last few days, it's been creating flash objects on my website via the PHP Ming functions.
If that sounds like a lot of techno-babble, well, it is. In simple terms, it's a way I can create drawings on my website that can be animated (or not), but are also vector-based, so they're resolution-independent. This originally caught my attention because someone at my wife's church wanted to know if I could help making a neat animated splash screen for their website. I said I couldn't because I didn't know how, nor have the tools, to create that type of graphics. But I realized I did have some ability to do that through PHP.
That lead to some experimentation, but that didn't last long. I then worked on getting my little bar graph-creation program converted to Flash. That was fun. Then I thought that I could use this same technique to finally fix my the counter on my Macintosh page that I never got to work beyond 99 days.
The trouble is that I want to overlay a perspective view of the counter on the image of the iMac's screen. Since the screen is tilted to the camera, it is not a perfect rectangle, so the text I put on it needs to be distorted to look right (perfect). I tried doing this with image slices, but these have to be rectangular, and it was laborious to pre-construct all possible digits to be placed on the screen. Perhaps if I could use the Ming flash tools, I could programatically distort some text and overlay it on top on the image.
My first attempts were promising, but I quickly was stymied by the lack of detailed information on how these PHP Ming functions work. I experimented some, but came to the realization that there is no facility arbitrarily distort objects with PHP Ming. I can rotate them and skew them, but I can't distort them.
So I'll have to try a different approach rather than the most robust one. I could create some digits that have the appropriate perspective already applied and then just place them on the image with PHP Ming, or maybe even the GD functions of PHP. I could ignore the perspective part of it, just skew the text, and hope it looks good enough. I'll think about it some before I start on my solution.
