pdfjs-viewer
pdfjs-viewer is a package for the Atom editor that makes it possible to view PDF files in Atom panes. It is a wrapper around Mozilla's PDF.js library including its viewer application, adapted for the Atom environment.
Comparison with other PDF viewer packages
pdfjs-viewer has the same purpose as the pdf-view and pdf-view-plus packages, but differs in several respects:
Other than pdf-view, this package features the full viewer UI, including
- outline / thumbnail / attachments view,
- text search,
- zoom levels,
- fullscreen mode,
- rotation,
- text selection and copy, and
- annotations.
Other than pdf-view-plus, the viewer has been reskinned in compliance with the request of PDF.js developers not to use it unmodified. UI elements blend in with the current Atom theme. Almost all icons have been replaced with alternatives from Font Awesome.
Moreover, links in the PDF have been made functional (internal and external, including file: links). Some UI elements and associated keyboard shortcuts have been removed because they serve no purpose within Atom.
Installation
Install from Atom's Settings/Install dialog (search for pdfjs-viewer) or via apm install pdfjs-viewer.
Usage
PDF files can be opened from the Atom user interface, e.g. from the project tree view, or programmatically through atom.workspace.open().
The PDF.js viewer supports a number of keyboard shortcuts, the most important ones are:
| shortcut | function |
|---|---|
| n or j | next page |
| p or k | previous page |
| ctrl+f | find |
| ctrl+g | find next |
| shift+ctrl+g | find previous |
| ctrl++ | zoom in |
| ctrl+- | zoom out |
| ctrl+0 | reset zoom |
| r | rotate clockwise |
| shift+r | rotate counterclockwise |
| F4 | toggle sidebar |
Zoom is also possible via ctrl + the mouse wheel. A click on an internal link scrolls to that position in the document, a click on an external link opens it with the associated application. If modified by ctrl or shift, external links are opened in a separate Atom window.
If the PDF has been generated by *TeX with SyncTeX support, a right click opens the source file in Atom at the corresponding line.
The package watches for file changes and reloads the PDF if necessary. Viewer panes are persistent across Atom runs.
