Use ImageMagick to Generate Image from Text?

由 ◇◆丶佛笑我妖孽 提交于 2021-01-29 05:30:37
问题 I'm trying to use ImageMagick to create thumbnail images that are 3840 x 2160. I need the image to have a black background and white text. The text should be centered vertically and horizontally. I want to be able to set a font size, but if the text would extend off the image, automatically decrease the font size so it fits with some amount of padding on the left and right. I will be doing this in bulk with several hundred thousand images. From what I've been able to find, it looks like you

Packer/Amazon EBS/Ubuntu - Inconsistent PPAs

由 北城以北 提交于 2021-01-29 04:21:06
问题 TL;DR; Packer is inconsistently ignoring the AWS Ubuntu PPAs, which is breaking my builds. Why? I have a job in Jenkins that uses Packer's Amazon EBS builder to create an AMI, based on the official Ubuntu 14.04 AMI. For some reason, every so often, the apt-gets that I use in the provisioner fail to use AWS' own PPAs, and only uses those at ubuntu.com: ==> amazon-ebs: Prevalidating AMI Name... ==> amazon-ebs: Inspecting the source AMI... ==> amazon-ebs: Creating temporary keypair: packer

解决Ubuntu系统“无法修正错误，因为您要求某些软件包保持现状，就是它们破坏了软件包间的依赖关系”的有效方法

解决Ubuntu系统“无法修正错误，因为您要求某些软件包保持现状，就是它们破坏了软件包间的依赖关系”的有效方法 ubuntu系统下安装东西，很多时候会出现版本冲突的情况： 有效的解决方法是使用aptitude来帮助降级。 首先安装aptitude 而后使用aptitude来安装前面有冲突的构建，同样也是要使用root的。 在安装的时候，第一个界面是问你，是否接受“不更新”的操作，一定要选"N" 后面则都是"Y"，一般情况下能够解决问题。 当然，如果你安装aptitude的时候遇到冲突，就要想其他办法，比如源码编译的方法安装aptitude。 感谢阅读至此，希望有所帮助。 来源： oschina 链接： https://my.oschina.net/u/124197/blog/4932248
