draws into the
frame.
This patch includes some changes I made...
* use blenders bitmap fonts (rather then own fonts)
* select font size
* user interface layout changes
* Marker as another image stamp option
Also added some new API calls
BMF_GetFontHeight(font);
BMF_DrawStringBuf(...); - so we can draw text into an imbuf's image buffer.
get_frame_marker(frame) - get the last marker from the frame.
IMB_rectfill_area(...) - fill in an image buffer with a rectangle area of color.
TODO - draw stamp info in 3d view, at the moment it just displays in the animation.
Preview Range is a useful tool for animating (espcially on longer timelines). It allows you to only run through a limited set of frames to quickly preview the timing of a section of movement without going through the whole timeline. It means you don't have to set/reset start/end frame for rendering everytime you wish to only preview a region of frames.
Hi Ton,
Attached is a patch (I know you've already got lots of them in the tracker ;-) ) for a feature that I've sometimes wanted. It seems that this sort of thing is supported in other packages, but I can't be sure.
Note: I may have left in a few bits and pieces I didn't mean to in the patch (this is off a source tree which had quite a few revisions in it, all of which was experimental)
== Preview Range ==
Preview range is useful for animating (espcially on longer timelines). It allows you to only run through a limited set of frames to quickly preview the timing of a section of movement without going through the whole timeline. It means you don't have to set/reset start/end frame for rendering everytime you wish to only preview a region of frames.
* 'Ctrl P' in Action/NLA/Timeline sets preview range. Click+drag to form selection-box defining region of frames to preview
* 'Alt P' in Action/NLA/Timeline to clear preview range
* 'Pre' button beside Start/End fields in timeline toggles whether start/end fields refer to scene or preview
* 'Ctrl Rightarrow' and 'Ctrl Leftarrow' jump to start/end of preview region when it is set
* 'S' and 'E' set the start/end frames of preview region when it is set (just like normally) in Timeline only
* In Action/NLA editors, frames out of preview region are now drawn darkened when preview-region is set
See the following page for more info later:
http://wiki.blender.org/index.php/User:Aligorith/Preview_Range
* 'On Selected Markers' and 'Between Selected Markers' now get a
correction for NLA action scaling .
* Bugfix for 'Between Selected Markers': now keyframes that occur
on and between the selected markers get selected.
* Bugfix for 'On Selected Markers': now it only considers selected
markers (it used to consider all markers)
* Now it is possible to invert the selection status of keyframes and markers.
These options can only be found in the Select menu in the header.
* It is also possible to select the keyframes that occur within the 2
'extreme' selected markers. Hotkey for this is Ctrl K
Now it is possible to column select keyframes that occur on the
same frame as selected markers with the hotkey: SHIFT K
More selection goodies to come :-)
Now time-markers work in all time-related spaces (i.e. Ipo,
Action Editor, NLA editor, TimeLine, Sound). The hotkeys and
functionality set should be the same for each of these modes
(with a few exceptions still). I've had to change a few hotkeys
here and there, so hopefully they aren't too bad.
Marker Operations:
MKEY - Add Marker
SHIFT MKEY - Rename marker (was CTRL MKEY)
XKEY - Delete Marker
PAGE UP - Jump to next marker
PAGE DOWN - Jump to previous marker
CTRL A - Select all markers
SHIFT G - Transform markers (NLA, IPO, Action)
G - Transform markers (Sound, Timeline)
CTRL SHIFT D - Duplicate markers (NLA, IPO, Action)
SHIFT D - Duplicate markers (Sound, Timeline)
BKEY - select markers and other keyframes (if any)
I've also made a few little tool additions to NLA and Action editors:
* NLA editor - Snap To Frame.
Now with the option to offset strip so that it starts at the current frame.
Added menus for this.
* Action editor - Snap To Frame
A few new menus for this too
- now draws on correct height
- selection is clipped correctly (did entire height)
- made showing scene markers default
Actually this implementation should have been a patch review... it was
done with entirely duplicating the code from timeline.c, whilst re-use
and generalizing markers has a preference. That way markers can become
supported in any time-based editor.
Will send an extensive review to Joshua Leung :)
- TimeLine: Marker grabbing works now. Use GKEY or select+drag, as usual
Holding CTRL will step with 1 second (corrected for ntsc dudes yes!)
Also added this in header pulldown
- Time values and Time grid draw fixed for Seconds display. It used to
draw steps of 2/5/10/20/50/100 etc. frames. Now does steps in seconds.
Again corrected for "Frames/Sec" value.
- "Frames/Sec" button redraws TimeLine, Secquencer, etc
- Bug fixed in editing Theme for TimeLine (was editing Image Select...)
- Added Grid color to Theme choices for Ipo, TimeLine, Sequencer, NLA,
Action, Sound. Was missing!
- Added Ckey for 'center view around current frame'.
- Completed View pulldown menu with remainder of options.
- prevented negative scaled views when start > end frame
Main change is that it's an own Space type now, not part of the Audio
window... the audio window should restrict to own options. This way
functionality is nicely separated.
Since it's the first time I added a new space (since long!) I've made an
extensive tutorial as well. You can find that here:
http://www.blender3d.org/cms/Adding_new_Space_Window.557.0.html
Notes for using timewindow;
- Add time markers with MKey
- CTRL+M gives option to name Marker
- Markers cannot be moved yet...
- Pageup-Pagedown keys moves current frame to next-prev Marker
- Xkey removes Markers
- If an object has Ipos or an Action, it draws key lines
- CTRL+Pageup-Pagedown moves current frame to next-prev Key
- Press S or E to set start/end frame for playback
Notes about the implementation in Tuhopuu:
- Add new Marker now selects new, deselects others
- Selecting Marker didn't work like elsewhere in Blender, on click it
should deselect all, except the indicated Marker. Not when holding SHIFT
of course
- Not exported functions are static now
- Removed unused defines (MARKER_NONE NEXT_AVAIL)
- Drawing order was confusing, doing too many matrix calls
- Removed not needed scrollbar, added new function to draw time values.
(Has advantage the MMB scroll works not confusing on a scrollbar)
- Added proper support for 'frame mapping'
- The string button (name Marker) had a bug (checked str[64] while str
was only 64 long)
- String button itself didn't allow "OK on enter"
- Made frame buttons in header larger, the arrows overlapped
- Removed support for negative frame values, that won't work so simple!
