On second pass it goes from bottom to top. Also, it defines required context for rendering each layer. Old rendering engine examines stack of layers in two passes.įirst, it is going from top to bottom and applies required transformations (when possible).

#Synfig studio examples code

If you examine code of any layer, you will see a function called accelerated_render() - this is a code of old render engine. This generally works much slower comparing to case when layer's code is ported to Cobra. But some layers are still use its code, in case if they are not ported to Cobra yet (Synfig fallbacks to old render engine). The new one (called 'Cobra') is the our latest development and it is the future of Synfig.Īnd there is an old one (without a name). On diagram: 'V' stands for ValueNodes, 'L' for layers, 'BL' for blank layer (completely transparent layer default background), 'BM' for blend method. That layer cannot distinguish the pixel data that comes from the next layer that's underneath, from pixel data from any other layer that's underneath. Note that a layer sees all the layers underneath as a single combined raster. Some layers (transforms, distortions, etc) just modify the raster result of the previous layers and pass that on to the next layer, instead of blending. The raster result of the previous layers is combined with the current one according to the set blending method. It doesn't carry any information about the vector shapes that it's representing, only their pixel data. A raster is an array of pixels, each pixel with its color/opacity. Once a layer has the values for it's parameters, it renders the intended shape or effect onto a raster. Since ValueNodes can be animated (meaning that they can change value at different points of time), so the entire tree needs to be evaluated on each frame. This process works recursively, going all the way down to the leaf nodes, calculating their value, then calculating the value of their parent, and so on until reaching the root of the node tree. If a parameter is ValueNode (calculated value), then it evaluates its parameters. When Synfig needs to render a frame it starts by evaluating parameters of layers. This ValueNode stores multiple values of parameter for different moments of time and calculates interpolated values between them.

So, we have following structure: gui -> libsynfigapp -> libsynfig This defines how application looks and behave.

synfig-studio/src/gui/ - Code of GUI written in GTKmm.

When user makes some change to Synfig file in GUI, then an action is called that does the actual modification. It contains code for actions - operations that transform loaded Synfig's file in some way. This is a layer between GUI and libsynfig (from synfig-core).

synfig-studio/src/synfigapp/ - Code of libsynfigapp library.

It uses libsynfig to read Synfig files and render them in any supported format.

synfig-core/src/tool/ - Code of synfig command-line tool (binary is simply called synfig).

synfig-core/src/modules/mod_noise/valuenode_random.cpp.

Implement a valuenode (see below on valuenodes).

synfig-core/src/modules/mod_noise/distort.cpp - Noise Distort Layer.

synfig-core/src/modules/lyr_freetype/lyr_freetype.cpp - Text Layer.

synfig-core/src/modules/mod_geometry/circle.cpp - Circle Layer.

synfig-core/src/modules/mod_gif/trgt_gif.cpp.

synfig-core/src/modules/mod_png/trgt_png.cpp.

Add support for exporting (rendering) to specific file format(s).

synfig-core/src/modules/mod_bmp/mptr_bmp.cpp.

synfig-core/src/modules/mod_png/mptr_png.cpp.

Add support for importing specific file format(s).

synfig-core/src/modules/ - Functionality of libsynfig can be extended with modules and this directory is a place for them.

The libsynfig library is used by all other Synfig's components.

It contains code of render engine and routines for reading/writing Synfig's files.

This is actually the main part of synfig-core. synfig-core/src/synfig/ - Code of 'libsynfig' library.If you want to hack on the interface, this is what you should look at. synfig-studio is the graphical editor.This directory contains the Synfig library and the Synfig command-line tool.

It renders scenes and knows how to read and write Synfig XML files. Every part of the Synfig project uses ETL in some way.

#Synfig studio examples portable

ETL is a template library that implements reference counting, portable threading and other low-level stuff.Synfig is divided into three components: ETL, synfig-core and synfig-studio.
