What is a .PBG file?
A .PBG file is a type of file called a Pixel Bender Graph File. It is made using a program called the Pixel Bender Toolkit. This program was used by people who create special effects for images, like those you see in Photoshop, or animations in Flash Player and After Effects. Inside a .PBG file, there is something called a processing graph. This graph connects different image filters, known as Pixel Bender kernels, together. It's like putting together pieces of a puzzle to process an image in a certain way, all within one file.
However, it's important to know that the Pixel Bender Toolkit, which is used to make and open these files, is no longer available. Adobe, the company that made it, has discontinued the program. So, if you have a .PBG file, you might find it difficult to open or use it without the original software.
More about what's inside a .PBG file: these files are saved in a format known as XML. This is a way of storing data in a structured, readable format. Within the .PBG file, there are sections of code that are wrapped in something called CDATA tags. These tags help keep the code organized and make sure that the file can hold both the actual source code and keep it formatted correctly in XML. It's a bit like having a box where you can keep both your notes and your notes' folder organized together.
One last thing to note is that .PBG files are related to, but different from, .PBK files. While both are used in the Pixel Bender Toolkit, .PBK files are specifically for the kernels or filters themselves. In contrast, .PBG files do not contain these .PBK files directly but include the plain text source code that describes how to connect multiple kernels together.
