Thread: How to place an icon in a window?

Please read my question!
I need to put an icon in a Window, and I need this icon to be written inside the source!

Example: my_icon = image data

I don't want the icon to be pulled from Hard Disk. And not from the internet or any place you can imagine!
my_icon = icon.png

Can anyone tell me how I can do this?
At the moment I use fltk to create the window, but I can't find it and I don't know how to assign the written icon data inside the source.

These allow you to build an image object from data in memory.

The PNG one would seem to be easy enough to try, since you already load "icon.png".

As I stated in the question. I want the png written in the source. Not in memory, so there is no icon.png

Example, below is an image written in source that I can save as a png if I want!

Creating the image below is easy, but it's not the image I want!
I want to have my image like the one I wrote in the source!

Code:

   int my_icon[13][13] = {
   { 15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15 },
   { 31, 31, 31, 31, 31, 31, 31, 31, 31, 31, 31, 31, 31 },
   { 47, 47, 47, 47, 47, 47, 47, 47, 47, 47, 47, 47, 47 },
   { 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63 },
   { 79, 79, 79, 79, 79, 79, 79, 79, 79, 79, 79, 79, 79 },
   { 95, 95, 95, 95, 95, 95, 95, 95, 95, 95, 95, 95, 95 },
   { 111, 111, 111, 111, 111, 111, 111, 111, 111, 111, 111, 111, 111 },
   { 127, 127, 127, 127, 127, 127, 127, 127, 127, 127, 127, 127, 127 },
   { 143, 143, 143, 143, 143, 143, 143, 143, 143, 143, 143, 143, 143 },
   { 159, 159, 159, 159, 159, 159, 159, 159, 159, 159, 159, 159, 159 },
   { 175, 175, 175, 175, 175, 175, 175, 175, 175, 175, 175, 175, 175 },
   { 191, 191, 191, 191, 191, 191, 191, 191, 191, 191, 191, 191, 191 },
   { 207, 207, 207, 207, 207, 207, 207, 207, 207, 207, 207, 207, 207 }};

Image of my_icon above written in source

Trying to explain better.

In the example below I have an image written in source!
Notice that it's not captured from anywhere on the computer, it's in the source!

I want to be able to convert a png image to text in the first place, the same or similar, or in some way that can be placed the same as the one in the source!

The code below creates the image file, described in the code

Code:

#include <stdio.h>

int main() {
   int i, j, temp = 0, width = 13, height = 13;


   // MY IMAGE
   int image[13][13] = {
   { 15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15 },
   { 31, 31, 31, 31, 31, 31, 31, 31, 31, 31, 31, 31, 31 },
   { 47, 47, 47, 47, 47, 47, 47, 47, 47, 47, 47, 47, 47 },
   { 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63 },
   { 79, 79, 79, 79, 79, 79, 79, 79, 79, 79, 79, 79, 79 },
   { 95, 95, 95, 95, 95, 95, 95, 95, 95, 95, 95, 95, 95 },
   { 111, 111, 111, 111, 111, 111, 111, 111, 111, 111, 111, 111, 111 },
   { 127, 127, 127, 127, 127, 127, 127, 127, 127, 127, 127, 127, 127 },
   { 143, 143, 143, 143, 143, 143, 143, 143, 143, 143, 143, 143, 143 },
   { 159, 159, 159, 159, 159, 159, 159, 159, 159, 159, 159, 159, 159 },
   { 175, 175, 175, 175, 175, 175, 175, 175, 175, 175, 175, 175, 175 },
   { 191, 191, 191, 191, 191, 191, 191, 191, 191, 191, 191, 191, 191 },
   { 207, 207, 207, 207, 207, 207, 207, 207, 207, 207, 207, 207, 207 }};


   FILE* pgmimg;
   pgmimg = fopen("pgmimg.pgm", "wb");
   fprintf(pgmimg, "P2\n");
   fprintf(pgmimg, "%d %d\n", width, height);
   fprintf(pgmimg, "255\n");

   for(i = 0; i < height; i++) {
      for(j = 0; j < width; j++) {
         temp = image[i][j];
         fprintf(pgmimg, "%d ", temp);
      }
      fprintf(pgmimg, "\n");
   }
   fclose(pgmimg);
}

Trying to explain better.
An image is just an array of bytes (like any other file).

How can I get the image below



and turn it into this

Code:

   // My Image
   int image[13][13] = {
   { 15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15 },
   { 31, 31, 31, 31, 31, 31, 31, 31, 31, 31, 31, 31, 31 },
   { 47, 47, 47, 47, 47, 47, 47, 47, 47, 47, 47, 47, 47 },
   { 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63 },
   { 79, 79, 79, 79, 79, 79, 79, 79, 79, 79, 79, 79, 79 },
   { 95, 95, 95, 95, 95, 95, 95, 95, 95, 95, 95, 95, 95 },
   { 111, 111, 111, 111, 111, 111, 111, 111, 111, 111, 111, 111, 111 },
   { 127, 127, 127, 127, 127, 127, 127, 127, 127, 127, 127, 127, 127 },
   { 143, 143, 143, 143, 143, 143, 143, 143, 143, 143, 143, 143, 143 },
   { 159, 159, 159, 159, 159, 159, 159, 159, 159, 159, 159, 159, 159 },
   { 175, 175, 175, 175, 175, 175, 175, 175, 175, 175, 175, 175, 175 },
   { 191, 191, 191, 191, 191, 191, 191, 191, 191, 191, 191, 191, 191 },
   { 207, 207, 207, 207, 207, 207, 207, 207, 207, 207, 207, 207, 207 }};

The Code above is exactly the picture shown!
It doesn't have to be exactly an int var
It can be any type of variable, but it can be written in the code as I showed
