问题 i am using imagick to create thumbnails for pdf documents. i get a fatal error on this line.. $imagick->readImage($file .'[0]'); I tried wrapping in a try catch but as i learned that doesn't work because it's a fatal error, not an exception. How would I gracefully catch this error? I am more concerned about using PHP to detect the error than solving the imagick problem, since any number of errors might come up with user pdf files. thanks! 回答1: Unfortunately it's not possible to catch fatal

问题 I have a php script to convert PDF files to images using imagick. It works on my local box but in the production server it fails to execute the command but not sure about the reason because I can't see my command execution output.

In order to solve this I need to know how can I log to a text file the output of this command execution in the shell from my php script, so I can after the fail download it by ftp and read it. exec('convert -density 150 -quality

一、web环境如下： 数据库：MariaDB 10.1.13 服务端脚本：php-7.1.8 web服务器：nginx-1.10.3 二、安装imagick需要先安装ImageMagick 1，url: http://windows.php.net/downloads/pecl/deps/ 2，下载（注意这里下载的版本不能太高，不然运行不起来，这个版本是我测试正常的）： ImageMagick-6.9.3-7-vc14-x64.zip 3，这里我安装到c盘imagemagick目录下，解压之后把ImageMagick目录下的bin目录下的文件复制到c:/imagemagick，这个目录如果不存在，需要创建一下 4，添加环境变量： 在PATH下添加：C:\imagemagick 5，新建系统变量 变量名：MAGICK_HOME 变量值：C:\imagemagick 三、 下载imagick扩展 1，url http://pecl.php.net/package/imagick/3.4.3/windows 2，下载：7.1 Non Thread Safe (NTS) x64，如图： 3，解压之后把文件复制到php\ext目录中 4，把CORE_RL magick .dll和CORE_RL wand .dll放在C:\Windows\System32中，如果不放也可以，只要能运行起来

Imagick PHP only displaying last page

由 怎甘沉沦 提交于 2019-12-11 17:08:29
问题 I am using imagick with PHP/Windows IIS. I have a simple script that converts a TIF file to PDF an presents it to the browser. It works flawlessly with single page TIF files, but with multiple pages, its only showing the last page. I understand that it shows the last page by default because the $im variable is an array. Any attempt I make to fix it makes it an invalid PDF. Below is my code. I am new to imagick and any help is appreciated! $im = new imagick("tmp/tmp.tif"); $im->setImageFormat(

Imagick annotateImage: how to set text position from the top left

由 懵懂的女人 提交于 2019-12-11 11:17:52
问题 I'm trying to create a wrapper function around annotateImage to be able to set the exact top and left positions of a given text. The default method sets the y-position from the baseline, which means there has to be a lot of experimentation involved if one wants to draw a text at an exact spot on an image. This is what I mean... $image->annotateImage($draw, 0, 0, 0, 'The quick brown fox'); In the above code, the text is invisible because the y position is 0. So to fix this, I've started with

Imagick: Convert bash command into php script

问题 There are images I want to remove the background of (or set it to transparent rather). For that reason, I have tested a bash imagick command that looks like this: convert test.jpg -alpha set -channel RGBA -bordercolor white -border 1x1 -fuzz 2% -fill none -floodfill +0+0 white -shave 1x1 test.png Because I need to use this in my php script, I need to translate this over now. What I've come up with is this: $imagick->readImage($path); $imagick->setImageAlphaChannel(Imagick::ALPHACHANNEL_SET);
