SoSFImage — Field containing a 2D image

       A  field  containing  a  two-dimensional  image.  Images  can  be  greyscale  (intensity), greyscale with
       transparency information, RGB, or RGB with transparency. Each component of  the  image  (intensity,  red,
       green, blue or transparency (alpha)) can have an unsigned one-byte value from 0 to 255.

       Values are returned as arrays of unsigned chars. The image is stored in this array starting at the bottom
       left corner of the image with the intensity or red component of that pixel, followed by either the alpha,
       the green and blue, or the green, blue and alpha components (depending on the number of components in the
       image).  The next value is the first component of the next pixel to the right.

       SoSFImages  are written to file as three integers representing the width, height and number of components
       in the image, followed by width*height hexadecimal values representing the pixels in the image, separated
       by whitespace. A one-component image will have one-byte hexadecimal values representing the intensity  of
       the  image.  For  example,  0xFF  is full intensity, 0x00 is no intensity. A two-component image puts the
       intensity in the first (high) byte and the transparency in the second (low)  byte.  Pixels  in  a  three-
       component  image  have  the  red  component  in  the  first  (high)  byte, followed by the green and blue
       components (so 0xFF0000 is red). Four-component images put the transparency byte after red/green/blue (so
       0x0000FF80 is semi-transparent blue). Note: each pixel is actually read as a single unsigned number, so a
       3-component pixel with value "0x0000FF" can also be written as "0xFF" or "255" (decimal).

       For example,

          1 2 1 0xFF 0x00

     is a 1 pixel wide by 2 pixel high greyscale image, with the bottom pixel white and  the  top  pixel  black.
     And:

          2 4 3 0xFF0000 0xFF00   0 0   0 0   0xFFFFFF 0xFFFF00

     is  a 2 pixel wide by 4 pixel high RGB image, with the bottom left pixel red, the bottom right pixel green,
     the two middle rows of pixels black, the top left pixel white, and the top right pixel yellow.

constunsignedchar*getValue(SbVec2s&size,int&nc)const
          Returns the pixels in the image as an array of unsigned chars. The size and nc arguments are filled in
          with the dimensions of the image and the number of components in the image; the number of bytes in the
          array returned will be size[0]*size[1]*nc.

     voidsetValue(constSbVec2s&size,intnc,constunsignedchar*bytes)
          Sets the value of this field to be an image of the given size, with the given  number  of  components,
          and  with  the  given  pixel values. size[0]*size[1]*nc bytes from the given array will be copied into
          internal storage maintained by the SoSFImage field.

     unsignedchar*startEditing(SbVec2s&size,int&nc)voidfinishEditing()
          These methods can be used to efficiently edit the values in an image field. startEditing() returns the
          size of the image in the size and nc arguments; writing past the end of the array returned is  a  good
          way to cause hard-to-find core dumps.
