 com.sun.midp.imageutil.ImageToRawConverter
| ImageToRawConverter | | public class ImageToRawConverter (Code) | | This class generates raw data from image according to
specified raw format and pixel format.
Supported formats are listed in static formatList array.
To add new supported format one should define new raw or/and
color format constants if needed, update static formatList array,
implement new conversion function byte[] _function_name_(BufferedImage image)
and update imageToByteArray function to support new format.

| ImageToRawConverter | | public ImageToRawConverter(int rawFormat, int colorFormat, int endian) throws IllegalArgumentException(Code) | | Constructs instance of ImageToRawConverter which will
convert images to raw data in specified here format.
Raw format and color format should be in list of
supported formarts, otherwise IllegalArgumentException
will be thrown.
Parameters:
rawFormat - required raw format
Parameters:
colorFormat - required color format
Parameters:
endian - required int format
exception:
IllegalArgumentException - if unsupported format |
| convertToRaw | | public byte[] convertToRaw(int[] imageData, int width, int height, boolean hasAlpha)(Code) | | Converts image to raw data in byte array.
Parameters:
imageData - image pixels in 32bit ARGB format
Parameters:
width - image width
Parameters:
height - image height
Parameters:
hasAlpha - true if image has alpha channel byte[] raw data |
| fillRawHeader | | void fillRawHeader(byte[] rawData, int width, int height, boolean hasAlpha)(Code) | | Fills byte array with raw header
byte RAW_HEADER[4] = {0x89, 'S', 'U', 'N'};
int32 width;
int32 height;
int32 hasAlpha;
Parameters:
rawData - byte array to fill header for, length of thatarray must be greater than 16, otherwise function fails (returns false)
Parameters:
width - width of the image
Parameters:
height - height of the image
Parameters:
hasAlpha - if image has alpha channel |
| isFormatSupported | | public static boolean isFormatSupported(int rawFormat, int colorFormat)(Code) | | Defines if format is currently supported.
Parameters:
rawFormat - raw format
Parameters:
colorFormat - color format true if format is supported false otherwise |
