[1.5] Creating Picture Variables On A Pc - Texas Instruments TI-89 Tip List

Exporting data to PC applications from the calculator
This is a simple matter of opening the variable in GraphLink, choosing Edit, Select All, then choosing
Edit, Copy. This copies the variable contents to the clipboard. From there, they can be pasted into the
PC application.
Or, in GraphLink, use Tools, Export, ASCII data to save the variable contents as a text file.
Importing and exporting with a Macintosh
George Dorner offers these tips, if you are using an Apple Macintosh.
Moving pictures or data to a Mac:
This works as one would expect with drag and drop and copy/paste technology, first using Graphlink to
create the variables of the correct type.
1. Create the text, matrix data, or graphic in the appropriate Mac application. I used SimpleText,
a scanned Dilbert comic, and Graphic Converter to experiment.
2. Copy the selected data (command C).
3. Open a new variable of the appropriate type with Graphlink at File->New (or command N).
(Use .9xm,.9xl,.9xg,.9xs for matrices, lists, pictures, or strings.)
4. Paste the data to the screen which opens.
5. Save As <yourname>.9xt for a text file for example.
6. Drag and drop the new file to Graphlink. If you are in Auto mode, numbers will be taken as
floating point. Change to Exact mode first if you want integers.
7. Use the variable as needed.
To size and crop a picture I use the shareware Graphic Converter from Thorsten Lemke.
Moving data from the calculator to your Mac application.
1. Open the variable in Graphlink.
2. Select and copy.
3. Paste to the appropriate Mac application.

[1.5] Creating picture variables on a PC

Picture variables have many practical uses on the TI-89 / TI-92 Plus. For example, they can be used
in programs to document the input variables pictorially. You can also use them as reference material,
for example, for schematics, or for pinouts for integrated circuits.
While it is possible to create the picture variables directly on the TI-89 / TI-92 Plus, it is faster and
easier to create them on the PC, then convert them to the calculator format. To convert them, use John
Hanna's Image File Viewer program, which you can get here:
