The story of CalcMosaic:
|
||
|
|
|
||
|
|
===================================================================
|
||
|
|
Villeroy's work inspired me the idea to pass the color value to
|
||
|
|
the BASIC macros in order to run faster.
|
||
|
|
|
||
|
|
http://forum.openoffice.org/en/forum/viewtopic.php?f=49&t=55857
|
||
|
|
|
||
|
|
But in the end I still cannot understand Villeroy's code. He
|
||
|
|
uses styles which I believe is faster. But it runs in a different
|
||
|
|
way than my Calc Mosaic. I cannot adapt his method. Also, I really
|
||
|
|
can not understand how the data work for his horse. He is so smart.
|
||
|
|
|
||
|
|
Here is my own version. It is 8 times faster than the previous
|
||
|
|
version. Now I learned how to inject and run OpenOffice BASIC macros
|
||
|
|
with Java UNO. I also learned that each Java UNO command triggers a
|
||
|
|
display refresh, which is costly. OpenOffice BASIC macros does not
|
||
|
|
trigger refresh, which is why it is faster.
|
||
|
|
|
||
|
|
Thanks for the people in the OpenOffice track of ApacheCon EU
|
||
|
|
2012, that I have a chance to review my code, rewrite it and
|
||
|
|
demostrate it.

The origin of this is a video "Stop-Motion Excel" posted on
|
||
|
|
YouTube on 2012-08-09.

This video quickly caught the media discusussion. Not only
|
||
|
|
because it is cool, but also that viewers found the author is not
|
||
|
|
using Excel, but OpenOffice Calc. This draw a discussion in the
|
||
|
|
OpenOffice development list, too. After watching the video, I feel I
|
||
|
|
can do it programmatically.

And then I presented it in the lightning talk in COSCUP 2012
|
||
|
|
Taiwan a week after, on 2012-08-18.

There is a hidden black button at A1 of the first sheet. Click

|

on the button to start the animation.

It seems that the talk without talk and the fresh-typed
|
||
|
|
presentation is too cool that many people did not notice what I
|
||
|
|
presented. :p But it helps to fill up the room when I presented an
|
||
|
|
introduction to Apache OpenOffice 3.4 the next day.
