Shapes and bitmaps can be transformed into 3D objects and get lighting and camera modifications applied to them. Notice that some effects only have some attributes while others contain color specifications as child elements like the ones explained in the previous post. ![]() I won’t explain their specification in detail because you can find a very good description in this website, but you can get an idea by taking a look at the following example where three effects are applied: glow, inner shadow and reflection: These effects are indicated with the a:effectLst tag inside the shape properties tag spPr. General shape effectsĮxamples of these effects are inner or outer shadows, reflections, glow… They can be applied both to vectorial shapes or bitmaps, and several of them can be applied at the same time. There are three types of effects that are managed separately in the DrawingML specification. After having worked in the preservation of color in shapes, we worked on the different effects that can be applied to shapes and bitmaps. We continue introducing features that will be part of the 4.3.0 release of LibreOffice, which is coming soon.
