Convert a php image to an ascii output image

Convert a php image to an ascii output image

This PHP function creates a simple JPG image ASCII art rendering. It uses Guangdong for heavy work, and some simple shift distribution colors. The color is then transferred to the hexadecimal value and the generated text is output to the browser. ASCII code from image art to PHP now, it's easy.

<? Php

Function image2ascii ($ image)
{
// Return value
$ Ret = '';

// Open the image
$ Img = ImageCreateFromJpeg ($ image );

// Get width and height
$ Width = imagesx ($ img );
$ Height = imagesy ($ img );

// Loop for height
For ($ h = 0; $ h <$ height; $ h ++)
{
// Loop for height
For ($ w = 0; $ w <= $ width; $ w ++)
{
// Add color
$ Rgb = ImageColorAt ($ img, $ w, $ h );
$ R = ($ rgb> 16) & 0xFF;
$ G = ($ rgb> 8) & 0xFF;
$ B = $ rgb & 0xFF;
// Create a hex value from the rgb
$ Hex = '#'. str_pad (dechex ($ r), 2, '0', STR_PAD_LEFT ). str_pad (dechex ($ g), 2, '0', STR_PAD_LEFT ). str_pad (dechex ($ B), 2, '0', STR_PAD_LEFT );

// Now add to the return string and we are done
If ($ w = $ width)
{
$ Ret. = '<br> ';
}
Else
{
$ Ret. = '<span style = "color:'. $ hex. ';" >#</span> ';
}
}
}
Return $ ret;
}
?>
