AvailabilityInline images and file transfers are only available in the nightly builds, which come from the master branch in the Github repo. These features are not in the v2 betas.
Using the imgcat script, one or more images may be displayed in a terminal session. For example:
iTerm2 extends the xterm protocol with a set of proprietary escape sequences. In general, the pattern is:
ESC ] 1337 ; key = value ^GWhitespace is shown here for ease of reading: in practice, no spaces should be used.
For file transfer and inline images, the code is:
ESC ] 1337 ; File = [optional arguments] : base-64 encoded file contents ^G
The optional arguments are formatted as
key=value with a semicolon between each key-value pair. They are described below:
|Key||Description of value|
|name||base-64 encoded filename. Defaults to "Unnamed file".|
|size||File size in bytes. Optional; this is only used by the progress indicator.|
|width||Width to render. See notes below.|
|height||Height to render. See notes below.|
|preserveAspectRatio||If set to 0, then the image's inherent aspect ratio will not be respected; otherwise, it will fill the specified width and height as much as possible without stretching. Defaults to 1.|
|inline||If set to 1, the file will be displayed inline. Otherwise, it will be downloaded with no visual representation in the terminal session. Defaults to 0.|
The width and height are given as a number followed by a unit, or the word "auto".
- N: N character cells.
- Npx: N pixels.
- N%: N percent of the session's width or height.
- auto: The image's inherent size will be used to determine an appropriate dimension.
More on File Transfers
By omitting the
inline argument (or setting its value to 0), files will be downloaded and saved in the Downloads folder instead of being displayed inline. Any kind of file may be downloaded, but only images will display inline. Any image format that OS X supports will display inline, including PDF, PICT, EPS, or any number of bitmap data formats (PNG, GIF, etc.). A new menu item titled Downloads will be added to the menu bar after a download begins, where progress can be monitored and the file can be located, opened, or removed.
Sample code for displaying images may be found here.
