推荐答案

如果要创建PDF文件的预览图像，请下载 ImageMagick .根据需要安装它们以创建映像.顺便说一句，这些应用程序可能已经安装在您的系统上(请先检查).

In case you want to create a preview image of your PDF file, download Ghostscript and ImageMagick. Install them as they are needed to create images. By the way, these applications may already be installed on your system (so check first).

使用以下PHP代码为PDF文件的所有页面创建预览图像(宽200像素).

Use the following PHP code to create preview images (200px wide) for all pages of your PDF file.

exec('convert "document.pdf" -colorspace RGB -geometry 200 "document.png"');

如果只想创建一个预览图像，请使用以下代码.您可以将方括号内的数字替换为所需的页码，从0开始.

If you only want to create one preview image, use the following code. You may replace the number inside the square brackets by the desired page number starting at 0.

exec('convert "document.pdf[0]" -colorspace RGB -geometry 200 "document.png"');
