Just display the svg (echo $svg) after the preg_replace to analyse it.

still not working but I think you can fix it:
can you pls check cod:

<?php

$usmap = 'images/mahir.svg';
$im = new Imagick();
$svg = file_get_contents($usmap);

$svg = preg_replace(
'/.cls-1{fill:red;}/'//on this this line is working,because when I try red color display me black fill on "echo",
,'/.cls-1{fill:aqua;}/'//possible problem is here,this command do not add color and then automatically add black color of cls-1 when I try display
,$svg
);

echo $svg;

$im->readImageBlob($svg);

$im->setImageFormat("png24");
$im->resizeImage(720, 445, imagick::FILTER_LANCZOS, 1); /*Optional, if you need to resize*/

file_put_contents ("converted/test.png", $im);
$im->clear();
$im->destroy();

?>

The echo command should display the SVG text stream (something like "<svg>...</svg>") somewhere in a log file or in the browser where you call the php file.

Please try this echo line and locate where this debug text is displayed.

Code: Select all

echo "DEBUG: MY UPDATED SVG TEXT = ".$svg;
Without that, you can't debug your code.

Moreover the preg_replace command is just a "Find and replace" text. Please read the documentation.

Code: Select all

<?php 

$usmap = 'mahir.svg';
$im = new Imagick();
$svg = file_get_contents($usmap);

$svg = preg_replace(
'/.cls-1{fill:red;}/'//on this this line is working,because when I try red color display me black fill on "echo",
,'/.cls-1{fill:aqua;}/'//possible problem is here,this command do not add color and then automatically add black color of cls-1 when I try display
,$svg
);

echo $svg;

$im->readImageBlob($svg);

$im->setImageFormat("png24");
$im->resizeImage(720, 445, imagick::FILTER_LANCZOS, 1); /*Optional, if you need to resize*/

file_put_contents ("converted/test.png", $im);
$im->clear();
$im->destroy();

?>

I fix it,
now preg_replace working perfect,but still not save images with colors,just save black color of fill,
but when I try "echo $svg" display svg image with changed color.
I thing problem is there:

$im->readImageBlob($svg);/////////// do no completly fill object "$im" with "$svg" !!!!

<?php

$usmap = 'images/mahir.svg';
$im = new Imagick();
$svg = file_get_contents($usmap);

$svg = preg_replace(
'/.cls-1{fill:red;}/'
,'.cls-1{fill:yellow;}'
,$svg
);

echo $svg;

$im->readImageBlob($svg);

$im->setImageFormat("png24");
$im->resizeImage(720, 445, imagick::FILTER_LANCZOS, 1);

file_put_contents ("converted/test.png", $im);
$im->clear();
$im->destroy();

?>

oh yes this is a known librsvg issue:
Styles are ignored in librsvg. Adding type="text/css" to the style element fixes it
Just update your svg file like this and it works!

Code: Select all

...
<style type="text/css">.cls-1{fill:red;}.cls-1,.cls-2,.cls-3{stroke:#fff;stroke-miterlimit:10;}.cls-3{fill:#207ab2;}
...

Re: change image color in svg format and save to png or jpg

Post by Mahir » 2016-11-23T11:11:30-07:00

this is corect cod:

<?php

$usmap = 'mahir.svg';
$im = new Imagick();
$svg = file_get_contents($usmap);

$svg = preg_replace(
'/.cls-3{fill:#([0-9a-f]{6});}/'
,'.cls-3{fill:aqua;}'
,$svg
);
echo $svg;

$im->readImageBlob($svg);

$im->setImageFormat("png24");
$im->resizeImage(50, 45, imagick::FILTER_LANCZOS, 1);

file_put_contents ("test.png", $im);
$im->clear();
$im->destroy();

?>

and this is svg file:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg id="Layer_1" data-name="Layer 1" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 1645.9 589.78">

<style type="text/css">.cls-1{fill:#333;}.cls-1,.cls-2,.cls-3{stroke:#fff;stroke-miterlimit:10;}.cls-3{fill:#207ab2;}
</style>
</defs>
<title>mahir</title>
<circle class="cls-1" cx="185.19" cy="185.19" r="184.69"/>
<circle class="cls-2" cx="795.91" cy="321.42" r="267.86"/>
<circle class="cls-3" cx="1486.21" cy="247.44" r="159.18"/>

Re: change image color in svg format and save to png or jpg

Post by Mahir » 2016-11-29T16:39:36-07:00

I found solution,I make changes, and display me on browser,but when i try save,not save changes.
maybe I need add something in svg file,but I do not know what.
changes are ignored in librsvg.I think I need add tipe="WHAT I NEED PUT HERE"

THIS IS CODE:

<?php

$usmap = 'svg/new.svg';
$im = new Imagick();
$svg = file_get_contents($usmap);


$parts = array(
'id="id-1"'=>'aqua',
'id="id-2"'=>'blue',
'id="id-3"'=>'aqua',
'id="id-4"'=>'red',//optional if svg have more id's
'id="id-5"'=>'red',
'id="id-6"'=>'red',
'id="id-7"'=>'red',
'id="id-8"'=>'red',
'id="id-9"'=>'red',
'id="id-10"'=>'red',
);

foreach ($parts as $part => $color) {
$svg = preg_replace(
'/'.$part.'/'
,'fill="'.$color.'"'
,$svg

);
}



echo $svg;

$im->readImageBlob($svg);

$im->setImageFormat("png24");
$im->resizeImage(400, 150, imagick::FILTER_LANCZOS, 1);

file_put_contents ("png/test.png", $im);
$im->clear();
$im->destroy();

?>

Hello Mahir,

With this code your svg xml elements contain 2 fill attributes like this:
(In your browser, use Right Click -> View source to visualize xml)
...
<text fill="aqua" transform="matrix(1 0 0 1 462.667 307.6924)" fill="#FF2A2A" font-family="'ArialMT'" font-size="100">blood</text>
...
And librsvg seems to fail to handle elements that contain severals fill attributes.

That's why you need to remove existing fill attributes before adding new one with this code:

Code: Select all

// Remove existing fill attributes
$svg = preg_replace(
'/fill="#([0-9a-f]{6})"/i'
,''
,$svg
);
So your final code should be:

Code: Select all

<?php 

$usmap = 'svg/new.svg';
$im = new Imagick();
$svg = file_get_contents($usmap);

// Remove existing fill attributes
$svg = preg_replace(
'/fill="#([0-9a-f]{6})"/i'
,''
,$svg
);


$parts = array(
'id="id-1"'=>'aqua',
'id="id-2"'=>'blue',
'id="id-3"'=>'aqua',
'id="id-4"'=>'red',//optional if svg have more id's
'id="id-5"'=>'red',
'id="id-6"'=>'red',
'id="id-7"'=>'red',
'id="id-8"'=>'red',
'id="id-9"'=>'red',
'id="id-10"'=>'red',
);

foreach ($parts as $part => $color) {
$svg = preg_replace(
'/'.$part.'/'
,'fill="'.$color.'"'
,$svg

);
}



echo $svg;

$im->readImageBlob($svg);

$im->setImageFormat("png24");
$im->resizeImage(400, 150, imagick::FILTER_LANCZOS, 1); 

file_put_contents ("png/test.png", $im);
$im->clear();
$im->destroy();

?>

thanks for replay,
it is working for fill,but when I try same code for font-size,do not working,like this:

// Remove existing font-size attributes
$svg = preg_replace(
'/font-size="?"/'
,''
,$svg
);

$svg = preg_replace(
'/id="id-3"/'
,'font-size="200px"'
,$svg
);


exactly,remove font size attribute but do not add new attribute
