convert hex(png) file to rgb values

I converted a PNG image to hex and am wondering if it is possible to decompress the hex into this type of format for each pixel of the image:

Opacity(0-255)-Red(0-255)-Green(0-255)-Blue(0-255)

I'm using a site/program that has heavy restrictions on images you can upload(quality, size, amount, etc,) but I can create images pixel by pixel. I was hoping to decompress the hex that I converted from the original PNG file to the format above so that I can create a simple function to build it on the screen. Come to think of it, is there a way to pull the RGB and transparency from the hex PNG file without any need for reformatting?

It is very easy you have to cut your hexvalue, and applicate an HEX to DECIMAL CONVERSION.

Ex : FFAACC00

FF = R = 255
AA = G = 170
CC = B = 204

00 = Transparency Full (FF = Transparency OFF)

If you need a program to do that you can use PNG2HEX.exe :

Download

(just drop your PNG File on it and it will create 2 files :

1- fileHex.txt with the value of each pixel in Hexa 2- FileRGB.txt with the value of each pixel in R G B

You can then modify values in these files and rebuild the png with the modification using HEX2PNG.exe
