imagick classes  Imagick, ImagickDraw, ImagickPixel, ImagickPixelIterator, ImagickKernel
Imagick compiled with ImageMagick version  ImageMagick 6.9.3-7 Q16 x64 2016-03-27 http://www.imagemagick.org
Imagick using ImageMagick library version  ImageMagick 6.9.3-7 Q16 x64 2016-03-27 http://www.imagemagick.org 

Demo1 代码如下:
ini_set('display_errors',1);  
header('Content-type: image/jpeg');  
$image = new Imagick('1.jpg');  
$image->thumbnailImage(100,0);

exit;

报如下错误:
图像“http://www.testf.com/test.php”因存在错误而无法显示。

报如下错误:
Fatal error: Uncaught exception 'ImagickException' with message 'UnableToOpenBlob `1.jpg': No such file or directory @ error/blob.c/OpenBlob/2702' in I:\wamp\Apache24\htdocs\test\test.php:3 Stack trace: #0 I:\wamp\Apache24\htdocs\test\test.php(3): Imagick->readimage('1.jpg') #1 {main} thrown in I:\wamp\Apache24\htdocs\test\test.php on line 3


请指点一下,谢谢。


回复讨论(解决方案)

检查你的 1.jpg 是否存在,路径是否正确

图片,路径正确

别逗了, ..... `1.jpg': No such file or directory 没有这样的文件或目录

别逗了, ..... `1.jpg': No such file or directory 没有这样的文件或目录



那你觉得这样如何呢。
<?php$imagick = new Imagick();$imagick->readImage('http://images.csdn.net/20160518/380-253.jpg');$imagick->writeImages('converted.jpg', false); exit;


错误提示:
Fatal error: Uncaught exception 'ImagickException' with message 'Failed to read the file' in I:\wamp\Apache24\htdocs\test\test.php:3 Stack trace: #0 I:\wamp\Apache24\htdocs\test\test.php(3): Imagick->readimage('http://images.c...') #1 {main} thrown in I:\wamp\Apache24\htdocs\test\test.php on line 3

Failed to read the file 读取文件失败

怎么是我觉得如何呢?
他已经清清楚楚的告诉了你问题的原因!

好吧。算我没问。

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
