How to convert a 24 Bit PNG to 3 Bit PNG using Floyd–Steinberg dithering? java.awt.image.BufferedImage should be used to get and set RGB values. On wikipedia, an example is given on how to conver...

I'm developing a custom thin-client server that serves rendered webpages to its clients. Server is running on multicore Linux box, with Webkit providing the html rendering engine. The only problem...

I've been looking for an optimized (i.e., quick) algorithm that converts a 24-bit RGB bitmap to a 16-bit (RGB565) bitmap using dithering. I'm looking for something in C/C++ where I can actually con...

I am developing a desktop based PHP application where we need to capture image of a person and print it on the label using Zebra GC420t printer The expected image should look like below image. ...

I've been using aforge's floyed-steinberg dithering method, but I noticed that you can't specify the amount of dithering. I'd like to be able to specify an amount between 0 and 100. So that if I as...

I'm having trouble converting images to 1bit dithered images using GraphicsMagic. The converted images are to be used as input for a thermal printer. I'm using the following command: gm convert i...

I have implemented several functions to convert sRGB to the CIE-L*a*b* color space. Now, I'd like to use that for dithering, but I'm unsure how to exactly discern which color is the "lower" color,...

On emulators running Android 4.0 or 4.0.3, I am seeing horrible colour banding which I can't seem to get rid of. On every other Android version I have tested, gradients look smooth. I have a Surfa...

I'm playing with webcam filters in HTML5. Got an Atkinson dither working pretty well for that old-school Mac feeling. Live | Code Now I'm trying to make a Bayer ordered dithering option for a 1...

I'm updating a plugin for Paint.net which i made some months ago, it's called Simulate Color Depth and it reduces the number of colors in the image to the chosen BPP and for a long time it have had...

I've got a live wallpaper out on the market which uses OpenGL to render some basic shapes and a flat plane. The simple lighting creates a gradient effect across the plane, which looks fine on most ...

I'm developing a texture atlas packer to use with OpenGL, and I'm currently looking for an open-source (it's better if it's a library, but an open-source software would be good as well!) solution t...

Several answers mention to use GradientDrawable.setDither(true) to draw smooth gradients in Android. That has no effect in my code. Any idea what I have to change to get a well looking gradient in ...

I loaded an 8bit grayscale image into octave with imread, then I saved it in ascii format and got a giant list of all of it's values. Then I dithered it with a 2x2 matrix in Java and printed out a ...

I know that Floyd–Steinberg dithering algorithm can't be implemented with pixel shader, because that algorithm is strictly sequential. But maybe there exist some higly parallel dithering algorithm ...
