错误 Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 3200 bytes) in $image_path = 'E:\www\01.jpg'; echo '1: ' . memory_get_usage() . '<br>'; $img1 = imagecreatefromjpeg($image_path); echo '2: ' . memory_get_usage() . '<br>'; $img2 = imagecreatetruecolor(800, 23277); echo '3: ' . memory_get_usage() .

Enable GD support in PHP

由 社会主义新天地 提交于 2020-01-03 12:23:32
问题 I'm trying to install pixelpost on an Apache server on windows. The installer is failing because: Pixelpost will not run if your PHP installation is not compiled with the GD graphics library. I've added the following line to php.ini extension=php_gd2.dll But I still get the same error message. When I run phpinfo() I don't see any reference to GD, so I guess it really isn't installed. I searched for php_gd2.dll and it's in the ext subfolder of my PHP root dir. I know nothing about PHP, so be

GD2 calling a function after form submit

由 徘徊边缘 提交于 2019-12-25 18:58:37
问题 The code below executes fine on its own, but when I wrap it with form element statements I get the error "call to undefined function flip in flipit.php line 11, 14 or 17 (depending on the radio button I selected in the form). This will eventually be incorporated into a file upload page allowing the uploader to flip and/or rotate their image on upload. So it needs to function with a form. Hope someone can see where I went wrong. Raw code that executes... <?php $src = '../../Uploads/Gallery

Is there a word wrap function for GD2 in php?

问题 people. I have slight problem with GD2 text on image. I have everything working and now i try to add text on image that can wrap within image. For example i have image with width 200px and large block of text. If you use imagettftext() text goes beyond borders of image and only partial text actually is visible. I have tried to use Zend's text wrap function, but it's not always producing accurate results here(not saying it don't work, only not in this case). Is there some dedicated GD2 method

ImageMagick or GD Library for image resizing and thumbnail creation?

由 瘦欲@ 提交于 2019-12-20 07:39:13
问题 I had been using the image resize class written by someone else to resize images or to create the thumbnails, here is the link to the class I had been using. http://www.white-hat-web-design.co.uk/articles/php-image-resizing.php I guess image GD library has some limitations for the resolution or the file size of images, it works fine for low resolution picture resizing(below 1024px) but it does not resize if I try to upload the high resolution jpeg image (i.e 3400px X 2200px) roughly, The

Magento resize() image quality: dirty white background

由 99封情书 提交于 2019-12-18 11:56:11
问题 I have a client who is seriously unhappy with the way their product thumbnails are rendering on Magento. The dodgy appearance is noticeable on two accounts: there is a dirty white background which has very light grey horizontal lines and secondly there is ever so slight color loss (loses contrast and saturation). I have removed ALL compression, set ALL quality to 100%, flushed image cache, experimented, broken, and fixed it all dozens of times, and nothing seems to work. This version of
