1 Color Palette using LUT Parametric Bitmap (Integer, Float or - - PowerPoint PPT Presentation

Parametric Bitmap (Integer, Float or Double) Minimum Value (0028,xxx4) e.g. 0 % Maximum Value (0028,xxx5) e.g. 100 %

1 Color Palette using LUT

LUT Would need:

• Number of LUT entries (if table is used)
• Minimum Value (First value mapped)
• Maximum Value (Last value mapped)
• Number of Bits

Segmented Palette Color Lookup Table

• Example:
• Describes:

R-Descriptor G- Descriptor B-Descriptor Seg0 0,205,255 0,1,255 0,1,127 Seg1 1,51,105 1,127,0 1,127,0 Seg2 0,128,0 0,128,0

• perator

range R G B constant 255 204 255 ramp 205 255 255 105 ramp 255 127 ramp 127 127

50 100 150 200 250 300 50 100 150 200 250 300

Segmented Palette Color Lookup Table

• Example:
• Describes:
• With
• First segment type
• 0 is discreet
• 1 is linear
• 2 is indirect
• Second is length
• Third is Value
• Discreet assume error
• Linear it is end value

R-Descriptor G- Descriptor B-Descriptor Seg0 0,205,255 0,1,255 0,1,127 Seg1 1,51,105 1,127,0 1,127,0 Seg2 0,128,0 0,128,0

• perator

range R G B constant 255 204 255 ramp 205 255 255 105 ramp 255 127 ramp 127 127
