![]() ![]() The sketch calls exit(), which is necessary to make sure that the file is properly written when complete. Hitting the 'q' key will quit the sketch. The following example records absolutely everything that happens while a sketch is running. Many Frames Into One File (With Screen Display) Use a keypress so thousands of files aren't created Note that # will be replaced with the frame number. Create a boolean variable to turn the PDF recording process on and off import processing.pdf.* It's also possible to save one frame from a program with moving elements. Single Frame from an Animation (With Screen Display) This is slower, but is useful when you need to see what you're working on as it saves. To draw to the screen while also saving a PDF, use the beginRecord() and endRecord() functions. Pdf.nextPage() // Tell it to go to the next page When finished drawing, quit and save the file PGraphicsPDF pdf = (PGraphicsPDF) g // Get the renderer This example creates a 100 page document: import processing.pdf.* It's possible to write every frame as a new page in the PDF document. ![]() (Note that no display window will open this helps when you're trying to create massive PDF images that are far larger than the screen size.) import processing.pdf.* This example draws a single frame to a PDF file and quits. See the examples below for different techniques. The createGraphics() function can also be useful. This library is frequently used with the core Processing function size(), with a combination of beginRecord() and endRecord(), or with beginRaw() and endRaw(). The source code is available on the Processing GitHub repository. The PDF library can flatten 3D data into a 2D vector file, but to export 3D data, use the DXF library. These vector graphics files can be scaled to any size and output at very high resolutions. The PDF library makes it possible to write PDF files directly from Processing.
