Image Array Tool
Hosted on github https://github.com/xitiomet/image-to-array
Simple Command line tool for converting images to data arrays. I made this to use with my RGB Shades (http://macetech.com/store/index.php?main_page=product_info&products_id=59), I wanted a simple way to convert any image into an array of pixels compatable with Arduino's FastLED Library. I may have gone past the original scope a bit, i added scaling and palette manipulation.
usage: ita
-2,--output-2d-array <arg> Output a RGB two dimensional C++ struct
array
-6,--output-base64 Output a base64 png string
-?,--help Shows help
-a,--output-ascii Output a 24-bit ASCII art image
-c,--output-array <arg> Output a RGB C++ struct array
-d,--details Output image details
-i,--input <arg> Input image file or URL
-o,--output <arg> Output file (.txt or .png)
-p,--input-palette <arg> Input image file for color palette filter
-r,--row-numbers Include row numbers on ASCII art
-s,--scale <arg> Scale image (ex: 320x240 or 0.5)
Example Usage
hearts.png (16x5 Image i want displayed on glasses)
$ ita -i hearts.png -c CRGB
CRGB hearts[80] = { CRGB(102, 102, 102), CRGB(131, 24, 24), CRGB(255, 97, 239), CRGB(131, 24, 24), CRGB(255, 97, 239), CRGB(131, 24, 24), CRGB(0, 0, 0), CRGB(0, 0, 0), CRGB(0, 0, 0), CRGB(0, 0, 0), CRGB(131, 24, 24), CRGB(255, 97, 239), CRGB(131, 24, 24), CRGB(255, 97, 239), CRGB(131, 24, 24), CRGB(93, 93, 93), CRGB(131, 24, 24), CRGB(255, 97, 239), CRGB(255, 97, 239), CRGB(255, 97, 239), CRGB(255, 97, 239), CRGB(255, 97, 239), CRGB(131, 24, 24), CRGB(0, 0, 0), CRGB(0, 0, 0), CRGB(131, 24, 24), CRGB(255, 97, 239), CRGB(255, 97, 239), CRGB(255, 97, 239), CRGB(255, 97, 239), CRGB(255, 97, 239), CRGB(131, 24, 24), CRGB(131, 24, 24), CRGB(255, 97, 239), CRGB(255, 97, 239), CRGB(255, 97, 239), CRGB(255, 97, 239), CRGB(255, 97, 239), CRGB(131, 24, 24), CRGB(96, 96, 96), CRGB(96, 96, 96), CRGB(131, 24, 24), CRGB(255, 97, 239), CRGB(255, 97, 239), CRGB(255, 97, 239), CRGB(255, 97, 239), CRGB(255, 97, 239), CRGB(131, 24, 24), CRGB(0, 0, 0), CRGB(131, 24, 24), CRGB(254, 93, 225), CRGB(255, 97, 239), CRGB(255, 97, 239), CRGB(131, 24, 24), CRGB(0, 0, 0), CRGB(113, 113, 113), CRGB(113, 113, 113), CRGB(0, 0, 0), CRGB(131, 24, 24), CRGB(255, 97, 239), CRGB(255, 97, 239), CRGB(255, 97, 239), CRGB(131, 24, 24), CRGB(0, 0, 0), CRGB(93, 93, 93), CRGB(0, 0, 0), CRGB(131, 24, 24), CRGB(255, 97, 239), CRGB(131, 24, 24), CRGB(0, 0, 0), CRGB(104, 104, 104), CRGB(123, 123, 123), CRGB(123, 123, 123), CRGB(104, 104, 104), CRGB(0, 0, 0), CRGB(131, 24, 24), CRGB(255, 97, 239), CRGB(131, 24, 24), CRGB(0, 0, 0), CRGB(89, 89, 89) };
if you want to use a struct other then CRGB any value can be passed to -c for instance "-c MyStruct" would produce
$ ita -i hearts.png -c MyStruct
MyStruct hearts[80] = { MyStruct(102, 102, 102), MyStruct(131, 24, 24), MyStruct(255, 97, 239), MyStruct(131, 24, 24), MyStruct(255, 97, 239), MyStruct(131, 24, 24), MyStruct(0, 0, 0), MyStruct(0, 0, 0), MyStruct(0, 0, 0), MyStruct(0, 0, 0), MyStruct(131, 24, 24), MyStruct(255, 97, 239), MyStruct(131, 24, 24), MyStruct(255, 97, 239), MyStruct(131, 24, 24), MyStruct(93, 93, 93), MyStruct(131, 24, 24), MyStruct(255, 97, 239), MyStruct(255, 97, 239), MyStruct(255, 97, 239), MyStruct(255, 97, 239), MyStruct(255, 97, 239), MyStruct(131, 24, 24), MyStruct(0, 0, 0), MyStruct(0, 0, 0), MyStruct(131, 24, 24), MyStruct(255, 97, 239), MyStruct(255, 97, 239), MyStruct(255, 97, 239), MyStruct(255, 97, 239), MyStruct(255, 97, 239), MyStruct(131, 24, 24), MyStruct(131, 24, 24), MyStruct(255, 97, 239), MyStruct(255, 97, 239), MyStruct(255, 97, 239), MyStruct(255, 97, 239), MyStruct(255, 97, 239), MyStruct(131, 24, 24), MyStruct(96, 96, 96), MyStruct(96, 96, 96), MyStruct(131, 24, 24), MyStruct(255, 97, 239), MyStruct(255, 97, 239), MyStruct(255, 97, 239), MyStruct(255, 97, 239), MyStruct(255, 97, 239), MyStruct(131, 24, 24), MyStruct(0, 0, 0), MyStruct(131, 24, 24), MyStruct(254, 93, 225), MyStruct(255, 97, 239), MyStruct(255, 97, 239), MyStruct(131, 24, 24), MyStruct(0, 0, 0), MyStruct(113, 113, 113), MyStruct(113, 113, 113), MyStruct(0, 0, 0), MyStruct(131, 24, 24), MyStruct(255, 97, 239), MyStruct(255, 97, 239), MyStruct(255, 97, 239), MyStruct(131, 24, 24), MyStruct(0, 0, 0), MyStruct(93, 93, 93), MyStruct(0, 0, 0), MyStruct(131, 24, 24), MyStruct(255, 97, 239), MyStruct(131, 24, 24), MyStruct(0, 0, 0), MyStruct(104, 104, 104), MyStruct(123, 123, 123), MyStruct(123, 123, 123), MyStruct(104, 104, 104), MyStruct(0, 0, 0), MyStruct(131, 24, 24), MyStruct(255, 97, 239), MyStruct(131, 24, 24), MyStruct(0, 0, 0), MyStruct(89, 89, 89) };
Once you have the array to your image here is how its used to create an effect for the RGB Shades:
void hearts()
{
if (effectInit == false) {
effectInit = true;
effectDelay = 500;
}
