resizeFill with a gif file

When doing something like $handle->resizeFill($image, 800, 400) on a GIF, a transparent whitespace is being added. This doesn't occur when the exact same image is a JPEG:

Original files:

src/Grafika/Imagick/Editor.php

when i do with blend

    $image->getCore()->setImageOpacity($opacity);

php got an error，Call to undefined function setImageOpacity???

PHP Version 7.1.8
imagick module version 3.4.3
Imagick compiled with ImageMagick version ImageMagick 7.0.1-8 Q16 x86_64 2017-07-10

how compare from string eg. file_get_contents()

the blend function has a bug

the blend function 's opacity param must be 1, when is 1.0 and the image2 is a png，the result image is not right，the image2 will be white background color

grafika似乎没有设置字间距的方法

imagick库可以设置字间距

$draw->setTextKerning($kerning);

于是我在text方法中加入了setTextKerning方法，由于GD库没有这个方法，使用时可以判断是GD库还是imagick库，希望新版本能加上

Flip-x and flip-y

Excellert lib! The only notable thing missing here is horizontal and vertical flip
Like this http://image.intervention.io/api/flip or https://github.com/claviska/SimpleImage#method-examples

setImageOpacity is deprecated from last stable version(3.4.4 - 2-19-05-02) You need upgrade

I can't use getVersion check this version.

This function setImageOpacity not support.

This function is deprecated from last stable version (3.4.4 - 2019-05-02) of PECL Imagick extension.

Resizing image makes it blurry by default.

RE: Version pulled during April 2017.

When resizing an image the final size appears slightly blurry when output to JPEG even when quality is set to 100%. It seems as if the 100% value is being ignored and the default 75-80% is being applied. The blurriness happens even if the image is resized the slightest amount and when any acceptable format was the original source (JPEG, GIF, PNG).

The following screenshot compares a Photoshop resize to a Grafika resize of the same amount using the same source file. Both files were resized by 75%. Pay close attention to the wording at the top of the box "new", "take pills easily" etc. The Grafika version more blurry and is an issue with the stakeholders of my project.

While I do not expect Grafika to be Photoshop, this is an issue for presentation.

Has anyone experienced this too?

resizeFill Bug in Ubuntu 14.04 PHP Imagick

resizeFill is buggy in Imagick. Try opening /grafika/examples/resize-modes.php in Ubuntu with Imagick as the editor, results to a buggy resize. See sc1.png. Image 1 is 55x75 and 100x100

sc2.png shows correct results if GD as editor is used. Image 1 and 2 are both 200x200.

Add support for WebP format

Seems like crop is adding the x and y offsets twice?

I t seems that in Grafika/Imagick/Editor.php lines 179 and 180 X and Y offsets are added to the $x and $y params.

But it seems that the offsets are already added at Grafika/Position.php on lines 119 and 120 right? Those values are used to initialize $x and $y later in the first place.

So Grafika/Imagick/Editor.php lines 179 and 180 can be just removed?

alpha value doesn't affect when using rotating

when I rotate png images colored border will appear according to rotation angle.
now I can set the color but it cant be transparent and with no color.
$color=new Color('ffffff',0.0);
$editor->rotate($image,$rotation[$i],$color);

$color=new Color('ffffff',1.0);
$editor->rotate($image,$rotation[$i],$color);

both are equal!

求支持php8或更高

需要更改为 setImageAlpha()

Error resize gif with GD

I try resize a image and show error

Exception in GifHelper.php line 292:
Error decoding GIF.400 247256

Add ability to set canvas color when creating a blank image.

Current API just creates a black image:

Grafika::createBlankImage(100,100);

With the new API, we add a third param Color. Below creates a blank canvas with a transparent white background:

use Grafika\Grafika;

$image = Grafika::createBlankImage(100,100, new Color('#FFFFFF', 0.0));

imagecolorat(): x,y is out of bounds

Hi,

There's an error thrown by Gd Editor when using smart crop on portrait images when the provided width of crop is equal or larger to that of the original image.

ex:

$image; // width = 200px, height = 500px
$image->crop($image->getWidth(), $image->getHeight());
// -> throws error

When I crop with $image->getWidth() - 1, it works, but then the image is 1px less than what I need
Also, it only does this with smart crop, other crop methods work.

Is it enough info?
Cheers!

grafika 如何把远程图片进行合并 结果以base64 输出?

找了半天,Google baidu bing 都没有解决的案例.

我觉得不应该啊.这是很正常的需求吧.

图片1=网络地址
图片2=网络地址

通过grafika 合成 得到图片三 为二进制 base64 格式 进行输出.

Working with EXIF

Is there any functionality to work with EXIF data, for example deleting some info?

Call to undefined method GdImage::getPixelIterator()

I have a Laravel application that uses Grafika and had been working for months if not years.

Without touching anything in my code, I installed the ImageMagick php extension and now I get this error:

Error:
Call to undefined method GdImage::getPixelIterator()

  at /srv/www/iframe.xxxx.com/vendor/kosinix/grafika/src/Grafika/Imagick/Filter/Dither.php:60
  at Grafika\Imagick\Filter\Dither->diffusion()
     (/srv/www/iframe.xxxx.com/vendor/kosinix/grafika/src/Grafika/Imagick/Filter/Dither.php:40)

  at Grafika\Imagick\Editor->apply()
     (/srv/www/iframe.xxxx.com/app/IFrame/Application.php:132)

The mere act of adding the ImageMagick extension (without modifying my code to use it in any way) has made this error appear.
