include a displayed image with a ticket upon ticket creation
The ImageTracPlugin allows uploading of images to tickets upon ticket creation. The image is displayed beside the ticket using the TicketSidebarProviderPlugin. This is useful when one wants to associate images with tickets. Additional work, such as displaying a thumbnail next to query results, may be done as time permits.
The ImageTracPlugin allows images to be attached to Trac tickets and displayed.
Several components are included in the ImageTrac plugin:
ImageTrac is the core of the ImageTracPlugin. This plugin processes
uploaded attachments and, if they are images, will create images of the appropriate size as dictated by the [ticket-image] section of the trac.ini configuration.
Two sizes are included by default, thumbnails and a default size, but an arbitrary number of sizes can be used. Configuration is given for the default case as follows
[ticket-image] size.thumbnail = 32x32 size.default = 488x
This specifies a thumbnail of 32 by 32 pixels and a default size of 488 pixels in width with a height taken from the aspect ratio of the uploaded image. Currently, images are not scaled up. Scaling is done with the Python Imaging Library and a front-end function packaged in cropresize.
ImageTrac can also enforce image uploading on ticket creation and
includes the ticket images in the data passed to the ticket.html template.
The DefaultTicketImage component allows the setting of a default image for a ticket. It maintains a database table, default_image, which stores which image is the default
The ImageFormFilter component adds a form on the ticket page that allows uploading of an image on ticket creation or ticket editing. Images so uploaded should become the default image (NOTE: there is currently a bug whereby this is not the case).
The SidebarImage component displays the images in an unordered list in the ticket sidebar using the TicketSidebarProviderPlugin.
The TicketImageHandler component serves the images at /ticket/<ticket id>/image/<size>. For example, the thumbnail of ticket 67 would be displayed at /ticket/67/image/thumbnail.
It is recommended that you enable all of the components of the ImageTracPlugin.
If you have any issues, create a new ticket.
