Does anyone remember the first CRT monitors? Those monochrome ones that had the ugly refresh line, scanlines, etc. This is an attempt to recreate that feel. I got the idea from tutsplus.com. Actually I used the method there almost exactly and changed the image. This effect makes use of RGB …
This bit of code uses blend modes to determine if two display objects intersect (if they are overlapping). It takes into account transparency, rotation, scale and translation. It enables near pixel level overlay detection. This forms the first part of any collision detection algorithm, firstly finding out if two objects …
This method will recolour an image to a new colour. However, it does give a washed out look to the image IMO. package net.avdw.image { import flash.display.BitmapData; import flash.filters.ColorMatrixFilter; import flash.geom.Point; import flash.geom.Rectangle; import net.avdw.color.extractARGB; /** * Makes a bitmap data object the color provided. * * @param destBitmapData The …
The below code will convert an image to sepia. package net.avdw.image { import flash.display.BitmapData; import flash.filters.ColorMatrixFilter; import flash.geom.Point; import flash.geom.Rectangle; /** * Makes a bitmap data object sepia. * * @param destBitmapData The destination bitmap data object. * @param sourceBitmapData The source bitmap data where the pixel data is retrieved. …
The following code will extract the four 8 bit channels from a 32 bit color. package net.avdw.color { /** * Extract four channels (a, r, g, b) from a 32 bit color. * * @param color A 32 bit color. * @return An object with properties a, r, g, b …
The following code will take the alpha, red, green and blue 8 bit channels and combine them into a 32 bit color. package net.avdw.color { /** * Combine four 8 bit channels into a 32 bit color. * * @param a The 8 bit alpha channel. * @param r The …
A while back I installed a new custom rom on my phone. Recently I changed the background from the default one to one that is similar to this effect. After a while I took more formal interest in this background image and decided that I could recreate it fairly easily. …
The below actionscript snippet will transform an image to grayscale using the ColorMatrixFilter. package net.avdw.image { import flash.display.BitmapData; import flash.filters.ColorMatrixFilter; import flash.geom.Point; import flash.geom.Rectangle; /** * Makes a bitmap data object grayscale. * * @param destBitmapData The destination bitmap data object. * @param sourceBitmapData The source bitmap data where the …
