Hello, and welcome to PixaFlux PixaFlux is an image editing application powered by a node graph engine The main difference between PixaFlux and a traditional image editing application is that instead of using layers, actions and history
The main difference between PixaFlux and a traditional image editing application is that instead of using layers, actions and history in PixaFlux you use the node graph to develop your image composition Let me explain first what is a node graph and how it compares to a layer stack A node graph is a set of nodes connected by links in PixaFlux almost all nodes are image operations A node can have input connections, attributes and output connections. The node graph uses the input values and the attributes to generate a new image with the operation applied, and returns it as output. For example in this node graph if I change the path attribute of the reader nodes, the final image is updated. if I change the opacity attribute in the blend node, the final image is updated. if I change the radius attribute in the smooth node, the final image is updated. All this in real time. Now, let me show you how easy is to simulate a layer stack. Let’s add a reader node and set it to open a bitmap from disk. This wall is our background layer. Let’s add another reader node with a graffiti. and now, let’s add a blend node, and connect the reader nodes to compose them together. This is a basic layer set up. What if the wall has some perspective? Now we need to add some perspective to the graffiti too. In a traditional application this would be a destructive action. normally accessible in a menu. In PixaFlux we just need to add a perspective node to the graph. and use the interactive gizmo to adjust the corners of the perspective box. Notice how the perspective box easily changes the position and size of the image. Let’s do some post-processing on the wall. Let’s add a ToLab node to convert this image to Lab color mode. And a curves node to adjust the Lightness. PixaFlux can mix in the same project images of different color modes. This is something you cannot do in a traditional layers application. where you have to commit to a single color mode for the whole project. Let me show you how easily PixaFlux mixes raster and vector images. I’m gonna add a shapes node and create a simple image using Bezier splines. Now let’s add a paint node and add some more detail. This looks very sharp, so I’ll use a smooth node to add some gaussian blur to the art. We need to add a blend node to compose these two images together. Ok, let’s go to the final node and see how all this stuff was composed. PERFECT PixaFlux has been designed with productivity in mind. So let me show you the real power of PixaFlux. Since the operations applied by the nodes are non destructive we can go back to any node and fine tune it. For example, I can go back to the Shapes node and make the eyes bigger. or I can decrease the amount of blurriness. Or I can adjust the curves operation. Or I can change the perspective. This is the real power of PixaFlux. You can iterate very fast, and fine tune your project in a very accessible and efficient way.
