|Version 15 (modified by 9 years ago) (diff),|
Provides screenshots upload and viewing subsystem for Trac. Uploaded screenshots can be described with short name, longer description and custom tags (if TracTags plugin is installed) and assigned to any number of components and versions registered in Trac. Screenshot uploads can be listed in timeline and screenshots can be referenced or embender in wiki pages. Plugin internally defines few interfaces for further extension.
Download the zipped source from [download:screenshotsplugin here].
Install plugin's egg and set variables in trac.ini configuration file according to your needs. Following list shows all of them with their default values:
[screenshots] title = Screenshots path = /var/lib/trac/screenshots ext = jpg png formats = raw html jpg png default_format = html default_components = default_versions =
title variable sets caption of item in Trac's main navigation menu,
path is location of directory where plugin should store uploaded and generated images and
ext is list of allowed file extension which can be uploaded. Using
formats option you can set in wich formats can be images downloaded and
default_format is format which will be returned if no format is specified in request. It must be one of formats supported by your PIL library installation. There are two meta formats:
raw denotes original format of uploaded image and
html is image embended in HTML page.
default_versions options sets default values for component and version filter. Set these variables according your Trac setup, otherwise, you would't see any screenshots with default filter.
If you run Trac in environment which needs to enable plugins explicitly put in trac.ini these lines:
[components] TracScreenshots.init.ScreenshotsInit = enabled TracScreenshots.core.ScreenshotsCore = enabled TracScreenshots.api.ScreenshotsApi = enabled TracScreenshots.wiki.ScreenshotsWiki = enabled TracScreenshots.timeline.ScreenshotsTimeline = enabled # For 0.11 branch. TracScreenshots.tags.ScreenshotsTags = enabled
If you don't have TagsPlugin installed replace last line with
tracscreenshots.tags.screenshotstags = disabled
Create directory you have specified with
path config option and make sure it is accessible by Trac server. The next step is to upgrade your environment:
# trac-admin <path_to_environment> upgrade
Screenshots plugin defines three permissions. With SCREENSHOTS_VIEW permission you can browse screenshots and see screenshot uploads in timeline. SCREENSHOTS_ADMIN adds you rights to uplad screenshots and SCREENSHOTS_FILTER allows you to modify component and version filter. You can add these permissions by typing following commands from commandline or you can use WebAdminPlugin to do it for you:
# trac-admin <path_to_environment> permission add <user> SCREENSHOTS_VIEW # trac-admin <path_to_environment> permission add <user> SCREENSHOTS_ADMIN # trac-admin <path_to_environment> permission add <user> SCREENSHOTS_FILTER
There are a macro [screenshot:<screenshot_id>] for screenshots referencing and embending. Expamples of usage is here:
See fig [screenshot:1]. Take a look at [screenshot:1 screenshot]. Screenshot of main window is: [screenshot:1,width=640,height=480].

align- Specifies image alignment in wiki page.
