Title: An image reading application allready for the TI-84 Plus C Silver Edition
Post by: critor on July 07, 2013, 10:01:06 am
The new TI-84 Plus C Silver Edition available for back to school 2013 does support a new kind of image variable: background images.
(http://tiplanet.org/forum/gallery/image.php?mode=medium&album_id=144&image_id=2047)

Such images can be generated with the TI-Screen Capture included in the TI-Connect 4.0 software or online thanks to SourceCoder (http://www.cemetech.net/projects/basicelite/sourcecoder2.php) on Cemetech.

But like on the TI-Nspire, those images supported natively have many limitations:
Fortunately, and it took less time than on the TI-Nspire, assemblybandit has just released IViewer, an image reading application for the TI-84 Plus C Silver Edition, and its convertion tool.

You can store as many images as you want. ;D(http://www.omnimaga.org/Themes/default/images/gpbp_arrow_up.gif)

Images can now be as large as the screen resolution: 320x160. ;D(http://www.omnimaga.org/Themes/default/images/gpbp_arrow_up.gif)

Images aren't limited to the screen resolution. ;D(http://www.omnimaga.org/Themes/default/images/gpbp_arrow_up.gif)

Scrolling is supported for images greater than the screen, but unfortunately the low refresh rate on this powerless hardware doesn't make it that useful.

If the refresh rate cannot be increased, some zoom support might be a good idea in order to limit the scrolling need.



But after the first TI-84 Plus C Silver Edition disappointing performance tests (http://ourl.ca/18413/339601), that's allready far better that what we could expect. ;D(http://www.omnimaga.org/Themes/default/images/gpbp_arrow_up.gif)

Nice work AssemblyBandit! :D I find it awesome how much hacking has already been made for the CSE :)

Correction: Built in images are actually 133x88, not 160x120 :P 

Congrats AssemblyBandit by the way. Nice job :)

I was talking about builtin background images.
Not builtin picture images.

yeah that's what I meant. They're really 133x88, because they only take the 265x165 area of the graph screen where we can draw stuff and each pixel except one row and column are doubled:

Unless TI really uses 160x120 but still displays over a smaller area, wasting memory? ???

If you aren't sure, you can always ask DrDnar or Kerm to confirm. Of course maybe you got a special calc (prototype?) where background images fills the entire screen, but in my case they only take the same area as regular pics and drawings.

EDIT: Actually correction, it's 133x83, not 133x88.

Hmm, can you use the pictures in programs? Like display it to the screen via that program?
(I don't have my CSE yet, so I'm not sure).

You can use both official and IViewer pictures in programs, yes :)

Yup :). If it wasn't for extreme memory consumption, Zelda: Sord of Atari could have looked like this:
