- *For more control, you need to write straight java code that uses p5. - * You can create two windows, that are shown on two separate screens, - * that have their own PApplet. this is just one of the tradeoffs of one of - * the things that we don't support in p5 from within the environment - * itself (we must draw the line somewhere), because of how messy it would - * get to start talking about multiple screens.

- * Creates and returns a new PGraphics object of the types P2D, P3D, and JAVA2D. Use this class if you need to draw into an off-screen graphics buffer. It's not possible to use createGraphics() with OPENGL, because it doesn't allow offscreen use. The DXF and PDF renderers require the filename parameter.
- *
It's important to call any drawing commands between beginDraw() and endDraw() statements. This is also true for any commands that affect drawing, such as smooth() or colorMode().
- *
Unlike the main drawing surface which is completely opaque, surfaces created with createGraphics() can have transparency. This makes it possible to draw into a graphics and maintain the alpha channel. By using save() to write a PNG or TGA file, the transparency of the graphics object will be honored. Note that transparency levels are binary: pixels are either complete opaque or transparent. For the time being (as of release 0127), this means that text characters will be opaque blocks. This will be fixed in a future release (Bug 641).

- *
- * To load several images asynchronously, see more information in the

- * As of 0096, returns null if no image of that name is found,

- *
- * Release 0115 also provides support for reading TIFF and RLE-encoded

- * Other TIFF and Targa files will probably not load, use a different

- * another application to use with Processing.
- *
- * Also in release 0115, more image formats (BMP and others) can

- * use Java 1.1 and 1.3, these formats are not recommended for
- * work that will be posted on the web. To get a list of possible
- * image formats for use with Java 1.4 and later, use the following:
- * println(javax.imageio.ImageIO.getReaderFormatNames())
- *
- * Images are loaded via a byte array that is passed to
- * Toolkit.createImage(). Unfortunately, we cannot use Applet.getImage()
- * because it takes a URL argument, which would be a pain in the a--
- * to make work consistently for online and local sketches.
- * Sometimes this causes problems, resulting in issues like
- * Bug 279
- * and
- * Bug 305.
- * In release 0115, everything was instead run through javax.imageio,

- * As a result, starting with 0116, the following happens:
- *
- * Rewritten for 0115 to read/write RLE-encoded targa images.

- * In most cases, loadShape() should be used inside setup() because loading shapes inside draw() will reduce the speed of a sketch.
- *
- * This method is useful if you want to use the facilities provided
- * by PApplet to easily open things from the data folder or from a URL,
- * but want an InputStream object so that you can use other Java
- * methods to take more control of how the stream is read.
- *
- * If the requested item doesn't exist, null is returned.
- * (Prior to 0096, die() would be called, killing the applet)
- *
- * For 0096+, the "data" folder is exported intact with subfolders,
- * and openStream() properly handles subdirectories from the data folder
- *
- * If not online, this will also check to see if the user is asking
- * for a file whose name isn't properly capitalized. This helps prevent
- * issues when a sketch is exported to the web, where case sensitivity
- * matters, as opposed to Windows and the Mac OS default where
- * case sensitivity is preserved but ignored.

The filename parameter can also be a URL to a file found online. For security reasons, a Processing sketch found online can only download files from the same server from which it came. Getting around this restriction requires a signed applet.

The extension parameter is used to determine the image type in cases where the image filename does not end with a proper extension. Specify the extension as the second parameter to loadImage(), as shown in the third example on this page.

If an image is not loaded successfully, the null value is returned and an error message will be printed to the console. The error message does not halt the program, however the null value may cause a NullPointerException if your code does not check whether the value returned from loadImage() is null.
Depending on the type of error, a PImage object may still be returned, but the width and height of the image will be set to -1.

THRESHOLD - converts the image to black and white pixels depending if they are above or below the threshold defined by the level parameter. The level must be between 0.0 (black) and 1.0(white). If no level is specified, 0.5 is used.
GRAY - converts any colors in the image to grayscale equivalents
INVERT - sets each pixel to its inverse value
POSTERIZE - limits each channel of the image to the number of colors specified as the level parameter
BLUR - executes a Guassian blur with the level parameter specifying the extent of the blurring. If no level parameter is used, the blur is equivalent to Guassian blur of radius 1.
OPAQUE - sets the alpha channel to entirely opaque.
ERODE - reduces the light areas with the amount defined by the level parameter.
DILATE - increases the light areas with the amount defined by the level parameter

-/**
- * Main graphics and rendering context, as well as the base API implementation for processing "core".
- * Use this class if you need to draw into an off-screen graphics buffer.
- * A PGraphics object can be constructed with the createGraphics() function.
- * The beginDraw() and endDraw() methods (see above example) are necessary to set up the buffer and to finalize it.
- * The fields and methods for this class are extensive;
- * for a complete list visit the developer's reference: http://dev.processing.org/reference/core/
- * =advanced
- * Main graphics and rendering context, as well as the base API implementation.
- *
- * Subclassing and initializing PGraphics objects
- * Starting in release 0149, subclasses of PGraphics are handled differently.
- * The constructor for subclasses takes no parameters, instead a series of
- * functions are called by the hosting PApplet to specify its attributes.
- *
- *
- * The functions were broken out because of the growing number of parameters
- * such as these that might be used by a renderer, yet with the exception of
- * setSize(), it's not clear which will be necessary. So while the size could
- * be passed in to the constructor instead of a setSize() function, a function
- * would still be needed that would notify the renderer that it was time to
- * finish its initialization. Thus, setSize() simply does both.
- *
- * Know your rights: public vs. private methods
- * Methods that are protected are often subclassed by other renderers, however
- * they are not set 'public' because they shouldn't be part of the user-facing
- * public API accessible from PApplet. That is, we don't want sketches calling
- * textModeCheck() or vertexTexture() directly.
- *
- * Handling warnings and exceptions
- * Methods that are unavailable generally show a warning, unless their lack of
- * availability will soon cause another exception. For instance, if a method
- * like getMatrix() returns null because it is unavailable, an exception will
- * be thrown stating that the method is unavailable, rather than waiting for
- * the NullPointerException that will occur when the sketch tries to use that
- * method. As of release 0149, warnings will only be shown once, and exceptions
- * have been changed to warnings where possible.
- *
- * Using xxxxImpl() for subclassing smoothness
- * The xxxImpl() methods are generally renderer-specific handling for some
- * subset if tasks for a particular function (vague enough for you?) For
- * instance, imageImpl() handles drawing an image whose x/y/w/h and u/v coords
- * have been specified, and screen placement (independent of imageMode) has
- * been determined. There's no point in all renderers implementing the
- * if (imageMode == BLAH) placement/sizing logic, so that's handled
- * by PGraphics, which then calls imageImpl() once all that is figured out.
- *
- * His brother PImage
- * PGraphics subclasses PImage so that it can be drawn and manipulated in a
- * similar fashion. As such, many methods are inherited from PGraphics,
- * though many are unavailable: for instance, resize() is not likely to be
- * implemented; the same goes for mask(), depending on the situation.
- *
- * What's in PGraphics, what ain't
- * For the benefit of subclasses, as much as possible has been placed inside
- * PGraphics. For instance, bezier interpolation code and implementations of
- * the strokeCap() method (that simply sets the strokeCap variable) are
- * handled here. Features that will vary widely between renderers are located
- * inside the subclasses themselves. For instance, all matrix handling code
- * is per-renderer: Java 2D uses its own AffineTransform, P2D uses a PMatrix2D,
- * and PGraphics3D needs to keep continually update forward and reverse
- * transformations. A proper (future) OpenGL implementation will have all its
- * matrix madness handled by the card. Lighting also falls under this
- * category, however the base material property settings (emissive, specular,
- * et al.) are handled in PGraphics because they use the standard colorMode()
- * logic. Subclasses should override methods like emissiveFromCalc(), which
- * is a point where a valid color has been defined internally, and can be
- * applied in some manner based on the calcXxxx values.
- *
- * What's in the PGraphics documentation, what ain't
- * Some things are noted here, some things are not. For public API, always
- * refer to the reference
- * on Processing.org for proper explanations. No attempt has been made to
- * keep the javadoc up to date or complete. It's an enormous task for
- * which we simply do not have the time. That is, it's not something that
- * to be done once—it's a matter of keeping the multiple references
- * synchronized (to say nothing of the translation issues), while targeting
- * them for their separate audiences. Ouch.
- *
- * We're working right now on synchronizing the two references, so the website reference
- * is generated from the javadoc comments. Yay.
