Convert image into array of pixels

I'm trying to display a battery icon on my Arduino LED screen. For that I need pixel level array (matrix) of that icon. Is there any way or tool where I can upload the image then it gives me the pixel representation of that image?

Assuming you know how to set a single pixel in the LCD screen and have a linux shell access, I can think in a way to hard code the image in your Arduino source. Although this approach is not so practical, it is certainly feasible and fun. So, lets do it!

Suppose you want to display this icon Nuclear icon named as nuclear.png.

By using the convert tool from the ImageMagick package you can obtain a text file that lists each pixel in the image through this command: 

convert nuclear.png nuclear.txt

The command above has as output the file nuclear.txt below:

You can see easily that, except for the first line, each line presents a pixel coordinate followed by the corresponding RGBA color value. You can obtain more information about this format in the official documentation.

By using some piped shell commands over nuclear.txt, we can generated a hard-coded array of integers in nuclear.cpp:

(echo "int pixels[] = {"; \
tail -n +2 nuclear.txt | tr -cs '0-9.\n'  ' ' | \
while read x y r g b junk; do echo "   $x,$y,$r,$g,$b,";done; \
echo "-1};") > nuclear.cpp

The nuclear.cpp content:

int pixels[] = {

   15,15,255,255,255,
-1};

Note that each line of the pixels array is formatted as row,col,r,g,b and the last element -1 is included intentionally. Once you have pasted this array in your source code, you can use the snippet below for iterating through pixels and showing them on the screen using a custom function:

int i = 0;
while (pixels[i]>-1) {
   int row = pixels[i++];
   int col = pixels[i++];
   int r = pixels[i++];
   int g = pixels[i++];
   int b = pixels[i++];

   //Show the pixel 
   //showPixel(row,col,r,g,b); You need to implement that.
}

That's it!
