Subject [jira] [Commented] (GUACAMOLE-280) Add support for the "faint" SGR flag
Date Sun, 21 May 2017 20:45:04 GMT

    [ https://issues.apache.org/jira/browse/GUACAMOLE-280?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16018978#comment-16018978
] 

Michael Jumper commented on GUACAMOLE-280:
------------------------------------------

The "faint" SGR flag is actually a "half bright" flag, defined as reducing the intensity by
half. Though it is reset when the intensity is reset (via SGR 21 or 22, for example), it is
a separate flag maintained independently from the bold flag. Both bold and half bright can
be set at the same time, resulting in essentially normal intensity.

> Guacamole's terminal emulator currently supports 16 colors - 8 normal colors, plus 8
additional colors through setting the "high intensity" SGR flag. Beyond this, there is a "faint"
SGR flag for lower intensity, which would add another 8 colors to this, but that flag is currently
ignored by Guacamole.
> Support for the "faint" SGR flag should be added to bring color handling into parity
with the Linux console and xterm.
