This article introduces the knowledge of "adding jitter to Unity3D batch pictures". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

A few days ago, the company had a project, because the art did a lot of background images and a large number of gradients were used too much, resulting in a very poor effect after compressing the picture, and the effect of RGBA16 was not ideal, so it would be too wasteful and efficient to use RGBA32. Later found that TexturePacker has a way to add picture jitter, because the project team used UGUI to manually set it one by one, which is too troublesome, so I made a tool. As shown in the following figure, you can obviously see that the effect of the RGBA16 gradient is not good, but the same RGBA16 effect is good with the addition of dithering.

As shown in the following figure, we tested the jitter algorithm FloydSteinberg with satisfactory results.

As shown in the following figure, put the images that need to add dithering into the input folder, and then execute a.sh (shell script under mac) a.bat (batch processing under win) will automatically output the dithered images to the output folder.

Needless to say about the installation of TexturePacker, just pay attention to the installation directory.

A.sh

#! / bin/bash

Project_path=$ (cd `dirname $0` Pwd) project_input= "${project_path} / input" project_output= "${project_path} / output" rm-rf "${project_output}" mkdir "${project_output}" texturePacker= "/ Applications/TexturePacker.app/Contents/MacOS/TexturePacker" cd ${project_input} files=$ (ls ${project_input}) for filename in $filesdo$ {texturePacker} "${project_input} / ${filename}"-format spritesheet-only-- texture-format png-- opt RGBA4444- -dither-type FloydSteinberg-- trim-mode None-- sheet "${project_output} / ${filename}" done

A.bat

Set project_path=%~dp0 set project_input=%project_path%\ inputset project_output=%project_path%\ output set texturePacker= "C:\ Program Files\ CodeAndWeb\ TexturePacker\ bin\ TexturePacker.exe" rd / s / Q% project_output%md% project_output% for / R% project_input%% f in (*. *) do (% texturePacker%% project_input%\% ~ nxf-format spritesheet-only-texture-format png-opt RGBA4444-- dither-type FloydSteinberg -- trim-mode None-- sheet% project_output%\% ~ nxf) pause

Through our test, most of the pictures can be solved by this method.
