[UPD 0.5] Pixel Piece Script Hack FAST Auto...

The default resolution is 72 dots per inch, which is equivalent to onepoint per pixel (Macintosh and Postscript standard). Computer screens arenormally 72 or 96 dots per inch, while printers typically support 150, 300,600, or 1200 dots per inch. To determine the resolution of your display, usea ruler to measure the width of your screen in inches, and divide by thenumber of horizontal pixels (1024 on a 1024x768 display).
Use matte to the change the pixel matte value to transparent.Follow the pixel coordinate with a method (see the color primitivefor a description of methods). The point method changes the mattevalue of the target pixel. The replace method changes the mattevalue of any pixel that matches the color of the target pixel.Floodfill changes the matte value of any pixel that matches thecolor of the target pixel and is a neighbor, whereas filltoborderchanges the matte value of any neighbor pixel that is not the border color (-bordercolor). Finally reset changes thematte value of all pixels.
Now whenever a large image is processed, the pixels are automagicallycached to disk instead of memory. This of course implies that large imagestypically process very slowly, simply because pixel processing in memory canbe an order of magnitude faster than on disk. Because your web site usersmight inadvertently upload a huge image to process, you should set a disklimit as well:
The second alternative is called a canvas. A canvas is a single DOM element that encapsulates a picture. It provides a programming interface for drawing shapes onto the space taken up by the node. The main difference between a canvas and an SVG picture is that in SVG the original description of the shapes is preserved so that they can be moved or resized at any time. A canvas, on the other hand, converts the shapes to pixels (colored dots on a raster) as soon as they are drawn and does not remember what these pixels represent. The only way to move a shape on a canvas is to clear the canvas (or the part of the canvas around the shape) and redraw it with the shape in a new position.
The bobbed source clip is sent to the MVTools2 plugin to perform motion analysis. Almost all these settings are used directly in MVTools2 functions. Read the MVTools2 documentation for more details on their purpose. Some settings can be altered for a speed / accuracy tradeoff. Less accurate motion search can result in blurring and/or oversharpening (in different circumstances) as well as slight distortions of visual elements. The faster presets gain speed by simplifying the motion search parameters, use the \"ShowSettings\" parameter or look at the table a short way into the script to see how.
Intuitively, a deinterlacer should just inject new fields into the source, leaving the original pixels untouched. The temporal blur/resharpen in this script means that doesn't happen - the source pixels are changed in the output. The (optional) source-match steps attempt to fix this and make the result closer to the source. They work by looking at the difference between output and source at different points in the algorithm and correcting for that difference.
Note 1: prior to using this function and before you enter CHDK mode, switch the camera into \"Record\" mode (also known as \"Shooting\" mode - where the lens is extended and the camera is ready to take a picture). There is a reminder dialog if you fail to do so.Note 2: If the Canon setting for 'review' is set to 'hold' it can stop the create badpixel script from completing.
By default, auto_write=True, meaning any changes you make to your pixels will be sent automatically. Since True is the default, if you use that setting, you don't need to include it in your LED object at all. We've chosen to set auto_write=False. If you set auto_write=False, you must include pixels.show() each time you'd like to send data to your pixels. This makes your code more complicated, but it can make your LED animations faster!
Therefore, RGB LEDs require three pieces of information and RGBW LEDs require FOUR pieces of information to work. So when you create the LED object for RGBW LEDs, you'll include pixel_order=(1, 0, 2, 3), which sets the pixel order and indicates four pieces of information involved. 59ce067264
