Name: Fundamentals of Image Pixel Processing
ID: m34461
Language: English (en)
Summary: Learn how to write skeleton code for creating a Bitmap object from an image file and how to display the bitmap. Learn two different ways to handle the image file, one of which results in a security issue that must be handled at compile time. Learn how to extract the BitmapData object from the Bitmap object and how to use the getPixels, setPixels, and setPixel32 methods to process the pixels in the bitmap. Learn how to apply a color inversion algorithm to invert the colors in a BitmapData object.
