IMAGINGJAVA-1502 QA 19.11 .NET 3549 Opaque parts

IMAGINGJAVA-1486 QA 19.11 Java 1431 Opaque parts (derived from IMAGINGNET-3623)

IMAGINGJAVA-1517 Support different raster data types in TIFF format

// below are 3 options for loading raw data

// Example 1. Loading raw data in accordance with its own raw data format. // Raw data after decoding is processed to eliminate format-specific effects (prediction and invert color component values). RasterImage image = (RasterImage)Image.load(“input.tif”); try { image.loadRawData(image.getBounds(), image.getRawDataSettings(), new CustomRawDataLoader()); } finally { image.close(); }

// Example 2. Raw data loading according to user-specified raw data format. // In this case, in addition, raw data is converted from its own format to the one specified by the user. // Note that so far not all raw data formats can be converted to other formats (since not all color converters are still implemented and registered at the ColorConverterFactory). RasterImage image = (RasterImage)Image.load(“input.tif”); try { RawDataSettings rawDataSettings = new RawDataSettings(); rawDataSettings.setPixelDataFormat(PixelDataFormat.getRgb24Bpp()); rawDataSettings.setDitheringMethod(DitheringMethods.PaletteIgnore); rawDataSettings.setLineSize(((image.getWidth() * rawDataSettings.getPixelDataFormat().getBitsPerPixel()) + 7) / 8);

image.loadRawData(image.getBounds(), image.getRawDataSettings(), new CustomRawDataLoader()); } finally { image.close(); }

// Example 3. Loading raw raw data without processing. // Format-specific effects (prediction and invert color component values) may be present in this data, therefore this data cannot be used in color converters without pre-processing. RasterImage image = (RasterImage)Image.load(“input.tif”); try { image.loadRawData(image.getBounds(), null, new CustomRawDataLoader()); } finally { image.close(); }

// Custom raw data loader class CustomRawDataLoader implements IPartialRawDataLoader { /**   * Processes the loaded data.   * @param rectangle The data rectangle.   * @param data The raw data.   * @param start The start data point. If not equal to (left,top) meaning that it is not full rectangle we have.   * @param end The end data point.
