[Bf-committers] Vert colours returning incorrect values.

[Campbell Barton]

Hi, Im writing some code that compares the vert colours of faces with 
eachother.

The code dosent work beacure the colour values returned from the 
selected  face colours is incorrect.

eg,  i have 9 white faces on a plane, and when I print the colour values 
is shows the last 2 faces to be a different colour.

Heres the code that assigns the colours


var props

	
  /* Here are vars where we store the colours to compare */
  /* extract of an email from Ton and Douglas Toltzman 
  What Ton is saying is that there are 4, 8 bit components stored in a 32
  bit, unsigned value.  I'm not sure of the order of components, but if Ton
  says "ABGR", then I'd presume the following would be correct
  - Ton
  Colors are 'packed' in an int, denoting bytes for ABGR respectively.
  Put a char pointer to the color, and read the color components  
  individually. Alpha is by default 255. */
  char *packed_color_array;
  /* face A- the active save */
  short redA1, greenA1, blueA1, redA2, greenA2, blueA2, redA3, greenA3,      blueA3, redA4, greenA4, blueA4,
      redB1, greenB1, blueB1, redB2, greenB2, blueB2, redB3, greenB3, blueB3, redB4, greenB4, blueB4;

      /* make sure the face has at lease 3 point before we go on */
      foundActFace=1;
      /* face A- the active save */
      packed_color_array = (char *) &tface[0].col;
      redA1= packed_color_array[3];
      greenA1= packed_color_array[2];
      blueA1= packed_color_array[1];        
      
      packed_color_array = (char *) &tface[1].col;
      redA2= packed_color_array[3];
      greenA2= packed_color_array[2];
      blueA2= packed_color_array[1];
    
      packed_color_array = (char *) &tface[2].col;
      redA3 = packed_color_array[3];
      greenA3 = packed_color_array[2];
      blueA3 = packed_color_array[1];
      if (mface->v4) {
        packed_color_array = (char *) &tface[3].col;
        redA4 = packed_color_array[3];
        greenA4 = packed_color_array[2];
        blueA4 = packed_color_array[1];
      }

Could anybody tel me why Im not getting all 255,255,255?
- Thanks
