Imagemagick convert multiple images to pdf size
提问by Kenny
For a project I am running ImageMagick to convert several images (all of the same size 960x570) into a single PDF.
对于一个项目，我正在运行 ImageMagick 将多个图像（所有大小都相同 960x570）转换为单个 PDF。
The command I'm running is:
我正在运行的命令是：
convert *.jpg pdf/export.pdf
Since the images are all the same size I expect each PDF page to be equal in size but this is not the case as you can see in the screenshot below:
由于图像大小相同，我希望每个 PDF 页面的大小相同，但事实并非如此，如下面的屏幕截图所示：
This is bit annoying since I don't know how I can force the size of each PDF page to be the same.
这有点烦人，因为我不知道如何强制每个 PDF 页面的大小相同。
I tested the PDF on both an android device, ubuntu pdf reader and adobe reader and they all show the different sizes.
我在 android 设备、ubuntu pdf 阅读器和 adobe 阅读器上测试了 PDF，它们都显示了不同的大小。
Thanks for helping!
感谢您的帮助！
EDIT1:After testing out a few more things as suggested by Marc B and Basti I managed to put the same size on the JPG (uploaded) images.
EDIT1：在按照 Marc B 和 Basti 的建议测试了一些其他东西之后，我设法在 JPG（上传的）图像上放置了相同的尺寸。
The problem still persists with the images that are generated using webkit2png (Python script that converts a webpage/html file to an image). After trying (almost?) everything in the convert command I can't get these generated images to shop up properly in the PDF as you can see below:
使用 webkit2png（将网页/html 文件转换为图像的 Python 脚本）生成的图像仍然存在问题。在尝试（几乎？）转换命令中的所有内容后，我无法让这些生成的图像在 PDF 中正确购物，如下所示：
Any help would be much appreciated!
任何帮助将非常感激！

After a few seconds of using google, I found this:
使用谷歌几秒钟后，我发现了这个：
-size <geometry> width and height of image
-size <geometry> width and height of image
Example given by them:
他们给出的例子：
$ convert -size 320x85 canvas:none -font Bookman-DemiItalic -pointsize 72 \
-draw "text 25,60 'Magick'" -channel RGBA -blur 0x6 -fill darkred -stroke magenta \
-draw "text 20,55 'Magick'" fuzzy-magick.png
