| BitmapImageSource | | public class BitmapImageSource extends MemoryImageSource (Code) | | A memory image source whose memory representation consists of
a packed bitmap (32 bits packed into each int) and an IndexColorModel
describing the colors represented by the bits (i.e. the background color
maps to pixel value 0 and the foreground color to pixel value 1).
version:
1.8 |
| Constructor Summary | |
| public | BitmapImageSource(int w, int h, int pix, IndexColorModel cm)
Create an image source for an image of the given width and height,
with packed bitmap data stored in pix[] and using the given
IndexColorModel to translate the bits into colors.
Parameters:
w - The width of the image
Parameters:
h - The height of the image
Parameters:
pix - The bitmap data, packed 32 pixels per int. |
| Method Summary | |
| protected static IndexColorModel | makeColorModel(Color fg, Color bg)
Create an IndexColorModel of size 2 that translates color 0 to the given
background color and color 1 to the given foreground color. | | protected static byte[] | translatePixels(int pix, int width, int height)
Translate bitmap image data into byte image data.
Takes a bitmap packed 32 pixels to an int (i.e. |
| BitmapImageSource | | public BitmapImageSource(int w, int h, int pix, IndexColorModel cm)(Code) | | Create an image source for an image of the given width and height,
with packed bitmap data stored in pix[] and using the given
IndexColorModel to translate the bits into colors.
Parameters:
w - The width of the image
Parameters:
h - The height of the image
Parameters:
pix - The bitmap data, packed 32 pixels per int. The data mustbe padded so that each scanline starts on an int boundary.
Parameters:
cm - The color model describing the meanings of 0 (background)and 1 (foreground). |
| makeColorModel | | protected static IndexColorModel makeColorModel(Color fg, Color bg)(Code) | | Create an IndexColorModel of size 2 that translates color 0 to the given
background color and color 1 to the given foreground color.
Parameters:
fg - The desired foreground color
Parameters:
bg - The desired background color An IndexColorModel which maps 1/0 to the given colors. |
| translatePixels | | protected static byte[] translatePixels(int pix, int width, int height)(Code) | | Translate bitmap image data into byte image data.
Takes a bitmap packed 32 pixels to an int (i.e. 1 bit of data per pixel,
plus padding), and returns one byte of data per pixel, no padding.
Parameters:
pix - The input pixel data (bitmap data)
Parameters:
width - The width of the input bitmap
Parameters:
height - The height of the input bitmap A byte array containing the translated bitmap. |
