![]() By following other techniques some wonderful results can be obtained. ![]() The ASCII ART image is not wonderfully clear but at least one can catch the drift. But nevertheless, it was an interesting exercise. It can get quite scientific and will involve far more math calcs than the simple approach that I have followed here. The image can be reduced if one for eg take blocks of let's say 5 x 5 pixels and work out what character would best represent the 5 x 5 pixels. How Do We Create Cool Symbols Using The Keys On Our Keyboard Text art/ ASCII art can be drawn using any text editor, online or offline. Certain modes work best for certain types of images. Mode: This determines the pre-processing that is applied to the image before thesholding it into a pure black and white image. I have done this on a 7" tablet so that the display can fit the ASCII image. The image will be converted into pure black and white using a threshold, and then the resulting image will be converted into text art using Braille Unicode characters. Thus, every pixel in the bitmap is represented by an ASCII character in the ASCII ART image. This is a very oversimplified way of doing it - have just used the average of each pixel's RGB values to decide upon the ASCII character to be used for each pixel. Note that the project uses inline Java code and you will need a B4A version that supports inline Java code to run the project (with the JavaObject library enabled). Have used a text size of 2 for the label and have set the typeface to MONOSPACE. The ASCII ART image is actually a label with the label's text set to the ASCII string that was generated from the bitmap (image on the left). The project uses 70 ASCII characters to generate an ASCII ART image from the bitmap. The drawing itself it took about 4:40, and my phone died partway through filming.Have done this purely for the fun of it. I ended up doing this conversion myself because I wanted an accurate brightness model for the particular font I was using, and because it’s not that hard. Now that I can generate arbitrary text, I had to select an image and render as characters. ![]() Marlin’s implementation for G5 worked on the first try. Marlin’s Bezier support is turned off by default so I had to turn on G5 in the firmware. Dont forget to click the spacesunderscores button to fill the white space with underscore characters so that when you paste it somewhere, it doesnt collapse all the spaces. I can then generate g-code for any character at any size at any location by scaling and offsetting the coordinates and emitting G5 commands for Bezier curves. Welcome to the textart.sh collection of number text art You can copy and paste these art pieces using the buttons below each piece. I have to remove a lot of text art because steam limited the comments on 1000 characters only. I then wrote a program that parsed out the Bezier paths from the SVG file and split it into a few Bezier paths for each character. The auto-generated paths are not that great so I heavily edited the paths manually to my liking. On a plotter, of course graphics are native and characters require an extra step, so this is dumb… for fun.įor this I created a toolpath font by generating raster characters of the fixed-pitch “OCR-B” font, then performed centerline tracing using Autotrace (as a plugin for Inkscape). ![]() While the finished product is in no way “better” than other rendering techniques, I find this approach really amusing because the entire purpose of ASCII art is to render graphics when only characters are available. I’ve been working on plotter capabilities lately, and I’m ready to reveal my secret project:
