Practically all access to enum data is read-only.

Border and circle select wait for input by default.
This commit uses bool properties on the operators instead of
magic number (called "gesture_mode").
Keymaps that define 'deselect' for border/circle select
begin immediately, exiting when on button release.
|
|
Use same convention as all others.
Remove 'select' since these are used for zoom as well.
|
|
In preparation for modal operators storing their properties,
no need to keep mouse-paths around.
Also use generic function for lasso properties.
|
|
Replace with operator type 'last_properties'.
Also use generic function for circle gesture properties.
|
|
Replace iroundf with round_fl_to_int, add other types

For example, if you have two keyframes:
k1 = 1px, k2 = 10px
it was doing:
1px, 9px, 8px, ..., 3px, 2px, 10px
instead of:
1px, 2px, 3px, ..., 8px, 9px, 10px

The recalc flag must be enabled for new interpolated strokes.

Also remove duplicate & mismatching comments from grease-pencil header.
Keep comments close to implementation to avoid getting out of sync.

Please do not add useless tooltips! We have enough messages to translate
already...

The problem was that the strokes in the copy-paste buffer could be keeping
dangling pointers to colors that were already freed. Therefore, this commit
makes it so that when copying the strokes, we now make copies of the colors
and put them in a hashtable beside the stroke buffer. This is convenient,
as it saves us having to look up what colours need to be copied over each
time when pasting.

The problem was that newly pasted strokes were still using colours from
the original datablock. As a result, you'd either get an immediate crash,
or if you managed to save the file before it crashed, each stroke would get
reloaded with a dummy colour.
This commit fixes makes it possible to copy/paste strokes between datablocks
again. However, there are still problems when trying to paste across file
boundaries (i.e. copy strokes in one file, paste in another), which the next
commit will address.

The operator is indeed not adding frames but inserting them at the current frame (shifting all subsequent ones). Changed the operator name and description.
Approved by Antonio.

When moved the options to toolsetting, this part was missing. The problem was not the pointer as suggested in D2629.
Thanks Arvīds Kokins for his help fixing this bug

Do not recompute both points's 2D coordinates for each segments, we can
copy over from previous one... Does not gives any measurable speedup off
hands, though.

Also de-duplicate poll functions

Now it is possible to select if the blank frame is created in active
layer only or in all layers.

Experimental option for the Reproject Strokes operator to project strokes on to
geometry, instead of only doing this in a planar (i.e. parallel to viewplane) way.
The current implementation is quite rough, and may need to be improved before it
is really ready for use. Potential issues:
* Loss of precision (i.e. stairstepping artifacts) from the 3D -> 2D -> 3D conversion
as we don't have float version of one of the projection funcs
* Jagged depth if there are gaps, since it will default back to the 3d-cursor plane
if no geometry was found (instead of doing some fancy interpolation scheme)
* I'm not sure if it's that useful for adapting GP strokes to deforming geometry yet...

layer doesn't have any frames
|

Now the eraser checks if there's an active frame with some strokes in it
before creating a new frame. There's no point in creating a new frame if
there are no strokes in the active frame (if one exists).
This still doesn't help much if there were strokes but they weren't touched though...

frame
This is a hardcoded keymapping that just calls the "Add Blank Frame" operator
introduced in the previous commit.
|
|
This operator adds a new frame with nothing in it on the current frame.
If there is already a frame there, all existing frames are shifted one frame later.
Quite often when animating, you may want a quick way to get a blank frame,
ready to start drawing something new. Or maybe you just need a quick way to
add a "placeholder" frame so that a suddenly-appearing element does not show
up before its time.

Also seems the new file forced trailing whitespace, which goes against

To make it faster to try different interpolation curves, there's a new operator
"Remove Breakdowns" which will delete all breakdowns sandwiched by normal
keyframes (i.e. all the ones that the previous run of the Interpolation op created)

interpolation
This commit introduces the ability to use the Robert Penner easing equations
or a Custom Curve to control the way that the "Interpolate Sequence" operator
interpolates between keyframes. Previously, it was only possible to get linear
interpolation between the gp frames.
Workflow:
1) Place current frame between a pair of GP keyframes
2) Open the "Interpolate" panel in the Toolshelf
3) Choose the interpolation type (under "Sequence Options")
4) Adjust settings (e.g. if you're using "Custom Curve", use the curvemap widget
to define the way that the interpolation proceeds)
5) Click "Sequence" to interpolate
6) Play back/scrub the animation to see if you've got the result you want
7) If you need to make some tweaks, undo, or delete the generated keyframes,
then repeat the process again from step 4 until you've got the desired result.

- "gp_interpolate"
The "gp_sculpt" settings should be strictly for stroke sculpting, and not abused by
other tools. (Similarly, if other general GP tools need one-off options, those should
go into the normal toolsettings->gpencil_flag)
Furthermore, this paves the way for introducing new settings for controlling the way
that GP interpolation takes place (e.g. with easing equations, or a custom curvemap)
|
|
* Reduce scope of variables
* Simplify a lot of the active_gpl->actframe->...->framenum stuff
* Missed some error messages
|
|
* Reshuffled some blocks of code for better ease of navigation/flow in the file
* Improved some tooltips
* Removed "Helper" tag from some functions that serve bigger roles
* Fixed some errant formatting
|
|
The interpolation operators (and their associated code) occupied a significant
portion of gpencil_edit.c (which was getting a bit heavy). So, it's best to split
these out into a separate file to make things easier to handle, in preparation
for some further dev work.

Things like `BLI_uniquename` had nothing, but really nothing to do in
BLI_path_util files!
Also, got rid of length limitation in `BLI_uniquename_cb`, we can use
alloca here to avoid overhead of malloc while keeping free size (within
reasonable limits of course).

Sometimes it can be useful to be able to keep onion skins visible in the
OpenGL renders and/or when doing animation playback. In particular, there
are two use cases where this is quite useful:
1) For creating a cheap motion-blur effect, especially when the before/after
values are also animated.
2) If you've animated a shot with onion skinning enabled, the poses may end
up looking odd if the ghosts are not shown (as you may have been accounting
for the ghosts when making the compositions).
This option can be found as the small "camera" toggle between the "Use Onion Skinning"
and "Use Custom Colors" options.
