TBase
The base class for luminance sources which supports cropping and rotating based upon the luminance values.
ZXing.BaseLuminanceSource.TBaseLuminanceSource
ZXing.PlanarYUVLuminanceSource.TPlanarYUVLuminanceSource
ZXing.RGBLuminanceSource.TRGBLuminanceSource
The TBaseLuminanceSource type exposes the following members.
| Name | Description | |
|---|---|---|
 | CreateLuminanceSource | |
 | CropSupported | (Overrides ZXing.LuminanceSource.TLuminanceSource.CropSupported .) |
| InversionSupported | |
| Matrix | Fetches luminance data for the underlying bitmap. Values should be fetched using: int luminance = array[y * width + x] and 0xff |
| RotateSupported | (Overrides ZXing.LuminanceSource.TLuminanceSource.RotateSupported .) |
| crop | Returns a new object with cropped image data. Implementations may keep a reference to the original data rather than a copy. Only callable if CropSupported is true. (Overrides ZXing.LuminanceSource.TLuminanceSource.crop .) |
| getRow | Fetches one row of luminance data from the underlying platform's bitmap. Values range from 0 (black) to 255 (white). Because Java does not have an unsigned byte type, callers will have to bitwise and with 0xff for each value. It is preferable for implementations of this method to only fetch this row rather than the whole image, since no 2D Readers may be installed and getMatrix() may never be called. (Overrides ZXing.LuminanceSource.TLuminanceSource.getRow .) |
| invert | (Overrides ZXing.LuminanceSource.TLuminanceSource.invert .) |
| rotateCounterClockwise | Returns a new object with rotated image data by 90 degrees counterclockwise. Only callable if is true. (Overrides ZXing.LuminanceSource.TLuminanceSource.rotateCounterClockwise .) |
| rotateCounterClockwise45 | Returns a new object with rotated image data by 45 degrees counterclockwise. Only callable if is true. (Overrides ZXing.LuminanceSource.TLuminanceSource.rotateCounterClockwise45 .) |
