gtkforphp / cairo Goto Github PK

Hi guys, thanks for all the work on Cairo for PHP7, really hoping for some help please.

Following any one of the font based examples (select-font-face.php, large-font.php, etc.) I am unable to to display anything more than squiggly lines and shapes instead of text. What am I missing?

For clarification: everything has compiled successfully and I can draw shapes, but the text "Hi" is displaying as per the attached screenshot. Using PHP 7.1.9.

"Oh RedHat, you make life angry!"

Yes, they do!
"old software is stable, and stable software is good."
Therefore: The older, the more stable. like Windows XP .)

Version 0.3.2 doesn't currently seem to compile with php7 because of the changes in ze3 (e.g. "zend_object_value" etc. don't exist anymore). Are there plans to update the cairo extension to compile successfully with php7?

Hi,
because 0.3.2 shows a (for me very bad) memory leak, i planned to go with master.
the good news: the memory leak is gone.

1st i suffered the FT_Free problem, which i solved by updating to a more recent version of libcairo + libfreetype

Now i suffer another segfault about every 10th request. I am using php-fpm, but also php-fcgi shows this behaviour:

    }

i tried different versions of freetype & cairo,
but the relevant component is cairo-pecl :(

i bisect'ed, it was introduced with commit 6b6fea4

The script i am using is:

  $fontFile = dirname(__FILE__) . "/arial.ttf";

  $surface = new \CairoImageSurface(
    CairoFormat::ARGB32,
    750,
    750
  );

  $context = new \CairoContext( $surface );
  $fontFaceObject = new \CairoFtFontFace($fontFile);
  $context->setFontFace( $fontFaceObject );
  $CairoFontMatrix = new \CairoMatrix();
  $CairoFontMatrix->scale( 12, 12 );

    for( $i = 0; $i < 10; ++$i ) {
        $angle = rand(1, 360);
        $CairoFontMatrix->rotate(deg2rad($angle));
        $context->setFontMatrix( $CairoFontMatrix );

       $x = rand(0, 750);
       $y = rand(0, 750);
        $context->MoveTo( $x, $y );
        $context->textPath( "blah" . $i );

Hi guys,

I'm not able to get the create-from-png.php and create-from-png-stream.php examples to work. I have copied and pasted the code exactly from the example files, along with the create-from-png-ref.png source image and my output file is always empty.

The confusing thing is that my PHP error log is quiet. If I misuse any of the functions I get errors reported as expected which leads me to believe that my implementation is correct.

Would anyone be able to help me determine what I am missing?

I'm using:

This error still exists, so i thought i give more detailed informations.

I am able to reproduce a memory leak with the following script:

unset($context);
unset($surface);
unset($fontFaceObject);

travis is not apparently building right in either branch, and appveyor is only building on the 7 branch
although I'm going to flip master to the 7 branch and archive current master as the 5 branch (need a release worthy port yet) the ci should still be building/testing on both branches

Hi Elizabeth,
i got an error while compiling with PHP7 alpha2 on OpenSuse 13.2:

Just FYI, please don't stress yourself, i only wanted trying it out, nothing more ☺️

Hi,
using php-fpm there seems to be a memory leak regarding FtFontFace

I found n-times the content of arial.ttf within allocated memory, where n equals number of requests.

therefore, the memory leak is directly related to sizeof($fontFaceObject) :-(

I'm currently only able to deploy version 0.3.2 via PECL, and I've encountered bugs which appear to have been fixed in the commits since that time (April 2012). Any chance of pushing a new release out?

tl;dr -- this is a request to rename existing tags and include any missing versioned commits as new tags. Here's the table of tags with their respective commit hash and commit date:

You can also see this applied in my fork: https://github.com/jamesan/cairo/releases.

I'm packaging this software for Arch Linux's user-contributed package repo. Part of the package spec includes a derivation of the upstream version string. When the upstream source is a git repo, the standard derivation expects version strings to be managed using tagged releases.

I forked this repo, intending to make a pull request containing consistently named tags including any missing ones, but pull requests don't support pulling in tags. Tags can only be created by repo contributors, so can someone with write access please apply these few tags?

Thanks!

Hi Elizabeth,

I wanted to try out cairo under php 7.1, but suddenly i got an error. Setting the Fillrule, Antialias (or any other enum) under php 7.0.x works fine, but under 7.1 it raises an TypeError :(

<?php

$surface = new \Cairo\Surface\Image(
    \Cairo\Surface\ImageFormat::ARGB32, 1, 1
);

$context = new \Cairo\Context($surface);

// var_dump( \Cairo\FillRule::EVEN_ODD );

try {
    $context->setFillRule( \Cairo\FillRule::EVEN_ODD );
    $context->setAntialias( \Cairo\Antialias::SUBPIXEL );
} catch (\TypeError $e) {
    echo $e->getMessage(), "\n";
}

gives me:
"Value 1 provided is not a const in enum Cairo\FillRule"

Please, can u take a look at it? I would be very appriciate.

Swen

It would be great if this extension is compatible for the next generation of PHP. I know that it would take a few modifications. But if we all want to use this great extension in the future, and to not loose too much time before PHP7 gets widely used, compatibility has to be made for sure.

I'm in the process of working through the examples and re-factoring them to work with PHP 7. After updating the first example I believe I've encountered a bug.

The updated example can be found here and the error message after execution is:

PHP Fatal error:  Uncaught TypeError: Value 1 provided is not a const in enum Cairo\Antialias in /home/adam/cairo/examples/a1-image-sample.php:21
Stack trace:

Hello everybody. Since PHP 8 was released last year, maybe some are looking for a port of the cairo-extension for PHP.
Here it is! It took quite a bit of work, but now it's finished after all.

I've created a fork and a new branch. The code can be found here:
https://github.com/swen100/cairo

What have I done:

• Ported to PHP8
• full rewrite of all tests and added tests for new methods
• added support for direct raster-output in format JPEG
• added 17 methods and class-constants to Cairo\Region (cairo 1.10)
• added 7 methods and class-constants to Cairo\Surface\Pdf (cairo 1.12, 1.16)
• added 2 methods and class-constants to Cairo\Surface\Svg (cairo 1.16)
• added 1 method to Cairo\Surface\Recording (cairo 1.12)
• added 5 methods to Cairo\Surface (cairo 1.12 and 1.14)

I would be happy if someone in charge and with access to the project could make a php8-branch in the original project to be able to take over the code from my branch.

Btw, the extension needed for cairo (datastructures) was also adapted to work with PHP 8 and can be found here:
https://github.com/swen100/structures

Many greetings, Swen

Hello,

I'm getting error when I try to compile. I'm running Ubuntu 16.04 with php 7.0.8. I complied and installed eosforphp/datastructures first. Thank you in advance.
