看起来图像调整大小效果不佳

我在寻找有关此行为的一些线索吗?我认为这是PHP的memory_limit或WP define('WP_MEMORY_LIMIT','X')问题?

有时调整图像大小,有时不调整大小,在其他情况下浏览器崩溃:

我使用Dreamhost作为共享主机,并限制了其7个上传限制.

打印错误,并上传了大小为6.4MB,宽度和高度为11684x3855的图像: 致命错误:在第254行的/PATH/wp-includes/media.php中耗尽了268435456字节的允许内存大小(尝试分配46736字节)

其他用户报告了相同的文件问题,例如3MB的文件,但宽度和高度更高(优于2000px或3000px).

欢迎任何帮助.

谢谢.
Im searching for some clue about this behavior? I think it is a PHP memory_limit or WP define('WP_MEMORY_LIMIT', 'X') issue?

Sometimes images are resized and sometimes not, in other scenarios the browser crash:

Im using Dreamhost as shared hosting, and their 7 upload limit.

Error printed with an uploaded image of 6.4MB of size and with a width and height of: 11684x3855: Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 46736 bytes) in /PATH/wp-includes/media.php on line 254

Other users reports the same issue with files, for example, of 3MB but with higher width and height (superior to 2000px or 3000px).

Any help is welcome.

Thanks in advance.

- 您需要更好地解释您的问题.不调整图像大小会怎样?你有错误吗?可以保存,但是不会生成图像吗?
  
  You'll need to explain your problem better. What happens when images are not resized? You get an error? It saves ok but the images are not generated?

正如@Brady所说,很多设置只能达到1024 x 1024,将来可能会随着分辨率,浏览器,互联网速度等统计数据的改变而改变,并且表明很多人在运行更好或更新的系统

减小图像尺寸,因为大多数用户不需要查看大于1024 x 1024的图像.我通常使用800 x 600或更大但小于1024 x 1024的图像.尽管我的大多数图像都较小,

As @Brady said alot of settings go only to 1024 x 1024 this will probably change in the future as stats for resolutions, browsers, Internet speeds, etc change and show that alot of people are running better or newer systems

reduce the image size as most users do not need to view a image that is bigger then 1024 x 1024. I usually use the 800 x 600 or bigger but less then 1024 x 1024. Most of my images though are smaller
- 通过smush.run来运行图像.在这种情况下,它首先无济于事.GD打开图像时,它将像位图图像一样在内存中打开它.每个像素都有自己的RGBA,因此每个像素大约占用3-4个字节的数据.您可以优化所有想要的图像,以免对其进行处理.
  
  runnnig the image through smush.it first wont help in this instance. When GD opens the image it opens it in memory like a bitmap image. Each pixel has its own RGBA so each pixel takes up roughly 3-4bytes of data. You can optimize the image all you want it wont help when you come to proccess it.

过去上传大型图像时,我遇到了同样的问题.当处理图像时,它会失败并以红色显示HTTP错误.但是,其他图像继续加载.并不是文件大小会失败,而是图像的像素宽度和高度.

默认的PHP设置中,每个图片最多可以处理的GD库为1,000,000像素,即1024px * 1024px

您知道吗:Truecolor的8,000像素乘以8,000像素乘以四个字节等于256兆字节.现在,我知道没有共享的托管虚拟主机可以让您的PHP内存限制为256MB

我能找到的唯一解决方案是减小上传的图像尺寸.或者说服您的虚拟主机提高PHP内存限制,这不太可能.

谢谢.一个问题,是否存在一些WP常量或挂钩以减少上传限制?这是在.htaccess中尝试的方法: php_value upload_max_filesize 4M php_valuepost_max_size 5M php_valuememory_limit 90M 但是上传限制继续为:7MB.

Thanks. A question, there exists some WP constant or hook to decrease upload limit? This is what tried in .htaccess: php_value upload_max_filesize 4M php_value post_max_size 5M php_value memory_limit 90M But the upload limit continues in: 7MB.
