This version makes it easy to change the image, and add your own if you like. Just add the image you want to use to the backdrop, and follow the instructions below. ☛ Click the stage to show/hide sliders. ☛ Click the green flag to render the image. ☛ Set the preset slider to anything but 0 to activate a preset*. To deactivate presets, so that you can play around with the sliders, set it to 0. ☛ Click "New image" to browse the images in the backdrop. When you find the image you want to use, click "Scan this image", and wait a few seconds while the image is being scanned. * The presets are ordered from least abstract (1) to most abstract (5) rendering.
✎ ✎ ✎ Notes ✎ ✎ ✎ Turbo Mode is recommended for smaller batch sizes, such as the ones used in presets 4 and 5. The "e" in "e exponent" is Euler's number. Here, it is used to control the ratio at which the number of dots increase as the pen size shrinks. https://en.wikipedia.org/wiki/E_(mathematical_constant) ✎ ✎ ✎ Credits ✎ ✎ ✎ Thanks to @griffpatch for his Ultra Fast Colour Image Scanner Tutorial: https://scratch.mit.edu/studios/31533631/ I followed the tutorial pretty closely when making the scanner. My code deviates a bit, but only to fit the project and my coding style. Thanks to @selim_tezel for "Portrait: Marilyn", which inspired me to make this project: https://scratch.mit.edu/projects/174294406 Thanks @Layzej for the NPR Guy image data. I think this version was originally used in "Stripple Effect": https://scratch.mit.edu/projects/72619120/ And thanks to the awesome studio "NPR: Non-Photorealistic Rendering", in which I found both of the above: https://scratch.mit.edu/studios/1440810/ Parrot photo by Andrew Pons on Unsplash: https://unsplash.com/@imandrewpons Umbrella photo by guy stevens on Unsplash: https://unsplash.com/@gstevens0884 Dog photo by Jane Almon on Unsplash: https://unsplash.com/@jfalmon Northern lights photo by Benjamin Suter on Unsplash: https://unsplash.com/@benjaminjsuter
