PHP QRCode generates a color QR code method, Phpqrcode generates

This paper describes the method of generating color QR code in PHP qrcode. Share to everyone for your reference, as follows:

This rewrites the next phpqrcode, streamlining some of the code, merging the output of PNG GIF jpeg.

Parameter description:

Call Mode:
Copy the Code code as follows: Qrcode::imgout ($text, $outfile = False, $level = qr_eclevel_l, $size = 3, $col =array (Array (255,255,255 ), Array (0,0,0)), $margin =2, $saveandprint =false, $logo =false, $bg =false, $type = ' png ');

$text string
$outfile = False

Output file

$level = L fault tolerance l 7% M 15% Q 25% H 30%
$size = 3 per pixel point size
$col =array (Array (255,255,255), Array (0,0,0))

Color Multidimensional Array RBG

[0] Background color array (r,g,b)
[1] around the upper left corner Array (r,g,b)
[2] around the upper right corner array (r,g,b)
[3] around the lower left corner Array (r,g,b)
[4] upper left corner Center Array (r,g,b)
[5] upper right corner Central Array (r,g,b)
[6] left bottom Corner Center Array (r,g,b)
[7] Content Array (r,g,b)
[8] Whether the content color changes//is not written code, reserved

$margin = 2//four peripheral distance
$saveandprint =false

Whether to output simultaneously when $outfile is true

$logo =false logo image address//logo tall and wide auto-clipping round angle transparent not written good $bg=false//Background image array

[0] Image address
[1] Background width 0 is unchanged
[2] High background 0 to maintain aspect ratio
[3] The ratio of the logo width to the background width of the smaller value example 0.8 is 80%
[4] logo from the background left margin 0 is centered to the right beyond the left
[5] logo from the background top margin 0 for the center of the bottom beyond the automatic upward

$type = ' png ' output type PNG GIF JPG
