哪些类型的文件可以在 Canvas 中预览?

Find your school's Canvas URL

To find your school or institution's Canvas URL, begin typing the name of your school/institution. Results will appear after you type at least 3 characters. For best results be as specific as possible. If you can't find your school, try using any part of your school's name or searching for your school district or state. You may also need to search for the school using the acronym or full name, for example "USU" and "Utah State University".

哪些类型的文件可以在 Canvas 中预览?

Canvas 支持各种可以在 Canvas 中转换的文档类型。如果提交的文件是作业和 Canvas DocViewer 支持的文件类型,文件将由 DocViewer 在 SpeedGrader 中显示。如果提交的文件不是作业或 DocViewer 支持的文件类型,文件将由 Google Previewer 显示。

Canvas 支持预览多达 100 MB 和 999 页的文档。

注意:

  • 作业提交后,SpeedGrader 最多花费十分钟时间用于显示支持 DocViewer 的文档。
  • 超过 30 MB 的文件需下载才能查看。

文档预览文件

Canvas DocViewer 支持下列文件类型:

.doc .odt
.sxi
.docx .pdf
.sxw

注意:

  • 文本文件 (.txt) 内的 HTML 不能在 DocViewer 中预览或注释,因此必须下载来查看内容。
  • Powerpoint文件(.ppt/.pptx)内的音频不能在DocViewer中预览,因此必须下载来查看内容。
  • 在 Canvas Teacher 和 Canvas Student 应用程序中,OpenDocument 文件 (.ods/.odt) 不能在 DocViewer 中预览。但是,如果用户在设备上安装了第三方应用程序,他们可以使用该应用程序来查看 OpenDocument 格式。
