Generate EAN13 or EAN8 barcodes directly on your calculator. Autogeneration of EAN13 checkdigit writing the first 12 numbers, and the screen can be scanned directly without need to print barcodes on paper to testing. Application can manage a barcode database, too. Compatible with both the 49G and 49g+ (ROM 1.23 and 2.0).
This algorithm draws Arcs (partial circles) in the GRAPH PICTure, using an approximative "circumference length" code. The result can sometimes be wrong by one pixel. Written in assembly language so it is very fast.
Draws a version of the Sierpinski carpet, a version of the Sierpinski triangle, the Mandelbrot set,
and a Julia set at a resolution of 0.01. For the 50g.
Grob editor in grayscale or in black and white with tools for lines, boxes, circles and ellipses, a zoom mode, fill in with patterns, g(x)or and replace grobs. Also has tools to rotate and make symmetries with grobs and alows one to edit a grob before replacing it.
Vertically or diagonally flips a grob. Also rotates grobs. Written in assembly language for speed; includes source code. Rotates the 131x64 standard grob 90 degrees in about 0.2 seconds on a 48G.
Searches all files containing graphics in the current directory and displays
them one after another with the NXT-key. The menu area displays additional
information on Size and name. The Arrow-Keys scroll the graphics whose right
lower boarder is marked. ENTER leaves the present graphic on the stack.
Many utilities for working with graphics, including commands to tilt, distort, resize, transform, and view graphics. Also does grob transformations and animations.
This is a a browser program written completely in User RPL. It will take a list of data from the first level of the stack and all your data will be displayed on the graphic environment called in User RPL (PICT). A bar will be shown and with up and down arrow keys you can "navigate" through your data or results. Optimized for the 50g.
