Working With Images
The TI-84PlusCE uses both pictures and background images. They are both stored in
Flash archive, but they are used in different ways.
Using Pictures and Backgrounds
• Image Vars (Image1 - Image9, and Image0) are variables stored in archive
memory. An Image Var is used as a Background Image in the graph area. Several
images are pre-loaded on the TI-84PlusCE. You can also convert images to TI-84
Plus CE Image Vars in the TIConnect™ CE software and load them to the calculator.
You cannot create images on the calculator.
Note: TIConnect™ CE software is available as a free download from
education.ti.com/go/download.
• Pic Vars (Pic1 - Pic 9, and Pic0) are also variables stored in archive memory. Pic
Vars can be created by drawing in the graphing area, and the changes saved and
recalled to the graphing area. Saving a Pic Var will not include the Background
Image behind your graphing area.
• Both Image Vars and Pic Vars are stored and run in Flash archive, not in RAM. They
are both accessible in the VARS menu.
• Image Vars and Pic Vars can only be shared with another TI-84PlusCE or TI-84 C
graphing calculator.
• TI-84 Plus Pic Vars cannot be shared between the TI-84 Plus and the TI-84 PlusCE
graphing calculators.
• If you perform a RAM reset on the TI-84 PlusCE, the Image Vars and Pic Vars
remain in Archive memory for use.
