Summary

This specs provides a comprehensive way of managing guides and guidesets (which are groups of guides).

Release Note

Rationale

Guides are one of the stronger workhorses of any vector editing application. Inkscape has a powerful set of options but I feel the way to manage guides is mainly focused on a per-guide basis and has lagged a bit behind the overall quality of the software. My points for this argument are:

  • The current dialog for manually setting guides properties is not as good as it should be since it tops the main window and the user has to pop-up the guides dialog for every editing, breaking the workflow. Also, is inconsistent with the way dock tabs work (much less obstructive).
  • The user can't change the color on a per-guide basis.
  • This spec adds basic managing operations such as add, remove, copy, visible/invisible and lock/unlock for guides.
    • Lock /unlock lets the user specify if the guides should be selectable along the objects or not.
  • It also deploys a complete UI framework for fitting the current types of guides (horizontal, vertical and angled) and adding other types of guides (see composition guides, or others to come).
  • This spec introduces the concept of a Guideset (or just Set). This is a bunch of guides that are grouped, having common managing options (copy, delete, visible/invisible, move and rotate).
    • If the user selects a set, all of the guides inside it are edited homogeneously.
    • Sets allows the user to arrange his guides in a comprehensive way (specially important when there are dozens of guides on the document).
  • Right now, for angled guides, the user can edit the angle and center of the guide numerically but not on-canvas. I try to improve this too.

Design

UI

Pretty self-explanatory...

The guides shown inside the viewer contains from left to right: visible/invisible, ID (name), and icon for type.

Using the drop-down menu we can select the type of composition guide:

On-canvas editing

The guides can be edited on canvas with only mouse and some key modifiers. These modifiers try to mimic the current behavior when transforming objects.

The rotation can be snapped as any other node to grids or other guides.

Usage

  • The IDs of the newly created guides should have more meaningful names like guide001, guide002, guide003, etc. More appropriate would be to have the names being "smart", i.e.: the name has some resemblance to the name of the guideset it is attached to. So if you have a guideset called left eye the guides are named left eye001, left eye002, etc. A guideset called right eye would have guides named right eye001, right eye 002, etc.
  • How does lock/unlock work?:
    • A locked guide can be moved and rotated on-canvas the same as an unlocked guide. However, the unlocked one will be selectable along the objects with the selector tool (both dragging a square and touch selection), and moving and rotating the object will do the same to the guides.
  • Guidesets:

TODO

* Detail how to use it: Sets like "text" and inside them guides like "text", "title1", "footnote", etc.

Discussion

I'm unsure about these ideas. Please, discuss below.

  • IDEA: Add snap option for every guide or every set, so the user is able to decide if snappable elements should snap to it or not.
  • IDEA: Add attach option so a guide or guideset can be attached to an object, so selecting and transforming the object automatically moves and transforms the guides.
