10770,Add configuration option for image type of workflow diagram,enhancement,0.12,Jun Omae,new,2013-01-08T09:35:41+01:00,2021-01-26T21:37:11+01:00,"It would be nice to use all image types dot is supporting to generate the workflow diagram. Especially with complex workflows the PNG image is almost unreadable and SVG would be the better choice.

I already have added a sample implementation.",Stephan Wurm

The error was due to the following ownership permissions:

{{{#!sh
$ ls -ald htdocs/tracworkflowadmin
drwxr-xr-x 5 root apache 4096 Feb 22 02:13 htdocs/tracworkflowadmin
}}}

The fix was straightforward after looking at the code to see what it was doing.

{{{#!sh
$ ls -ald htdocs/tracworkflowadmin
drwxr-xr-x 5 apache apache 4096 Feb 22 02:13 htdocs/tracworkflowadmin
}}}

I was just thinking that this scenario is probably not all that uncommon, and it might be nice to provide an error message to guide the user to a solution in this case.",Ryan J Ollos

Currently I have these add-ins and while I can edit the core options through the workflow admin panel, anytime I want to configure the features of the other add-ins, I have to edit `trac.ini` directly.

12015,Add graph view settings to the workflow admin panel,enhancement,,Jun Omae,new,2014-10-14T20:49:10+02:00,2017-03-19T02:11:17+01:00,"In addition to the hardcoded settings in trac.ini, having settings directly available on the workflow administration panel would allow for easier previewing of workflows. Also, in conjunction with #12014, this would allow users who cannot edit trac.ini to preview images in a way that suits them.

The following options should be present on the workflow administration panel:
  - diagram_colors
  - diagram_font
  - diagram_fontsize
  - diagram_size

In addition, the following options should be added to the workflow-admin section in trac.ini:
  - max_diagram_size

The addition of a max_diagram_size prevents abuse of the diagram_size option that would be available on the admin page (Preventing, say, a 10!^24 x 10!^24 image being rendered).",Keluri

A dropdown on the page could be used to select the workflow that needs to be customized",Chris Bush
