This week, I was mainly working on cleaning up and migrating the patches from my experimental branch to LO master.
merged patches were:
patches that are still in review are:
Here’s the file for last weeks demo but updated for this week (Simulated/Simulation was renamed to Physics across the whole implementation last week so it needed an update):
Here’s how the animation effect is expressed in the content.xml of the demo file:
<!-- excerpt from customshapesfalling.odp:content.xml -->
<anim:par smil:begin="0s" smil:fill="hold" presentation:node-type="on-click" presentation:preset-class="emphasis" presentation:preset-id="libo-physics-basic">
<loext:animatePhysics smil:dur="4s" smil:fill="hold" smil:targetElement="id1"/>
</anim:par>If you’d like to play around with animation effects and create new ones that combine physics based and existing ones. First you should pull the current implementation from my experimental branch. After that, you should create a dummy animation containing odp file and manually edit it’s content.xml creating an altered animation effect. Finally to see it in action use File -> Reload option.
Here is a file that has two example animations that I’ve created this way which combines physics animations with others:

Last Week: I implemented an ExtensionManager object to establish connection between Additions and Extensions dialog. With this object, I got all installed extensions and disabled their install buttons on the Additions list. Patch Finally, I fixed the crash. The crash was related to the use of smart pointers. I was storing UI components in a vector. But now, the shared:ptr of components are stored in the vector.
The Annual Report of The Document Foundation for the year 2019 is now available in PDF format from TDF Nextcloud in two different versions: low resolution (6.4MB) and high resolution (53.2MB). The annual report is based on the German version presented to the authorities in April.
The 54 page document has been entirely created with free open source software: written contents have obviously been developed with LibreOffice Writer (desktop) and collaboratively modified with LibreOffice Writer (online), charts have been created with LibreOffice Calc and prepared for publishing with LibreOffice Draw, drawings and tables have been developed or modified (from legacy PDF originals) with LibreOffice Draw, images have been prepared for publishing with GIMP, and the layout has been created with Scribus based on the existing templates.

Lothar Becker, Chairman of TDF Board of Directors, has written in the welcome address:
What we have achieved so far goes beyond the most optimistic forecasts of the project’s founders back in 2010. After ten years, the challenge is still to further grow the project by leveraging the contributions of both volunteers and ecosystem members, engage new enthusiastic supporters in both areas, and increase the number of happy users worldwide. Our manifesto, the vision behind all our work, has to evolve in a new era of office productivity, with versions of LibreOffice on the desktop, in the cloud and on mobile devices!
I look forward to another great year for our global community, even with the current challenge of lockdowns in many locations, and the lack of in-person meetings and events because of the pandemic. I’m proud, honored and humbled to be part of this amazing project, and invite you all to keep on contributing to it in one of the many possible ways, and have fun together while achieving our common dream!
LibreOffice 7.0: the new major release of the best FOSS office suite ever is available on all OSes and platforms, and provides significant new features
Berlin, August 5, 2020 – The LibreOffice Project announces the availability of LibreOffice 7.0, a new major release providing significant new features: support for OpenDocument Format (ODF) 1.3; Skia graphics engine and Vulkan GPU-based acceleration for better performance; and carefully improved compatibility with DOCX, XLSX and PPTX files.

LibreOffice 7.0’s new features have been developed by a large community of code …
Having fun everyone. I wish you are all doing good in this tough time.
It was Adolfo who complaint about Colibre's failure to accomplish WCAG contrast guideline. He said the colors are too faint and everything looks washed out. Furthermore, MS Office 365 has since moved those colors to a brand new monoline style iconography. See this bug report for details
So I took the chance to update this Windows default icon theme. Luckily, the icon theme comes with SVG version, I can easily use bash script to automate a neccessary color conversion, and take the rest manually. In one month, I finally managed to finish this "Neo" Colibre. Hopefully this will benefit the largest LibreOffice user platform (approximately more than ~80%).

Last week I’ve started by working on support for Custom Shapes. At first I didn’t how could I get the related geometry information about Custom Shapes. Upon asking on IRC, mst (Michael Stahl) directed me to SdrObject class. Inspecting this class, found out a child of it that handles Custom Shapes called SdrObjCustomShape had a function SdrObjCustomShape::GetLineGeometry was returning exactly what I’ve wanted in the first place a B2DPolyPolygon that represents the shape! So I went ahead and created an implementation that if the shape type is CustomShape, it got corresponding SdrObject using it’s XShape and casted the SdrObject* to an SdrObjCustomShape* and got the B2DPolyPolygon from that. Then it triangulated this polygon using basegfx::triangulator::triangulate, and added resulting collection of triangles to a box2d body.
Later, since achieving such a result using an SdrObject was quite easy and took care of rotations and skews applied to the shape with ease, I wanted to drop my prior implementations for ClosedBezierShape and ClosedPolygonShape and use SdrObject for everything if possible. To make this happen, went back and inspected SdrObject again realizing SdrObjCustomShape::TakeXorPolygon used SdrObjCustomShape::GetLineGeometry. TakeXorPolygon according to it’s documentation was used for dragging objects but suited my case perfectly since it was returning B2DPolyPolygon representation for the corresponding shape. So I proceeded by using that for every type of shape and started to build a generalized implementation that wasn’t specific to shape type.
While doing so I’ve added support for shapes that were open, non-filled polygons or merely edges. Box2D required dynamic shapes to have an actual volume to properly simulate dynamic bodies. So I’ve set an arbitary width value and used it to offset copies of edge start and end points parallel to the edge normal, on opposite directions to each other giving them some volume. Looped through the whole B2DPolyPolygon constructing quadrilaterals that reperesented each edge and added these to box2d body.
Lastly, bezier curves that were triangulated resulted in a big performance hit since some of the custom shapes ended up having ~800 triangles, this amount of precision was mostly useless. To resolve this problem before doing anything with B2DPolyPolygons I’ve subdivided bezier shapes with basegfx::utils::adaptiveSubdivideByAngle giving it a fAngleBound of 20 degrees. Even though this is a pretty …
Hello, I want to share with you the progress of this week. Last Week: Minor bug in search function has been fixed.Patch The program crashes when I click Install Button. I’ve been trying to fix this bug all week. I tried too many things but couldn’t fix it. This Week TODO: Immediately fix the crash problem. Install/remove function
A few months ago, we announced Open Badges for LibreOffice contributors. These are custom images with embedded metadata, awarded to our most active community members to say thanks for their great work!
The metadata describes the contributor’s work, and the badge can be verified using an external service. Open Badges are used by other free software projects, such as Fedora.
Anyway, today we’re awarding 50 Open Badges to the most active members in our localisation community, based on Weblate activity so far this year. Congratulations to everyone who got a badge – we’ve emailed it to you! Here’s the list of winners:
We’ll be issuing more badges in the coming months, so stay tuned to the blog for more…
Here’s our summary of updates, events and activities in the LibreOffice project in the last four weeks – click the links to learn more…
tldr:
Started adding support for complex shapes, so that they are now simulated by their shape instead of their bounding box.
Up till this point, all shapes in the slideshows were approximated by their bounding box in the simulations.
Since it is not really pleasant to have everything simulated as boxes, last week I’ve started to add support for complex shapes that are represented by their polygon/curve shapes.
I’ve got the geometry information directly from XShapes.
There was a problem since Box2D only accepted convex polygons as shapes. So as a generalized solution I’ve triangulated shapes using basegfx::triangulator::triangulate() and added the resulting vector of triangles to a box2d body using individual fixtures for the triangles.
My main approach for creating complex shapes right now is converting the shape to a B2DPolyPolygon then triangulating it and adding the triangle pieces to a box2d body.
This approach worked OK for PolyPolygonShapes and ClosedBezierShapes. I will start this week by adding support for CustomShapes, hopefully it will be possible to convert them into B2DPolyPolygons and use a similar approach for them too.
