Method Summary |
static LookupTableJAI |
render(LUTProperties props,
int type)
renders a JAI LookupTable from a LUTProperties object with offset = 0 and length = 0x10000 |
static LookupTableJAI |
render(LUTProperties props,
int type,
int offset,
int length)
renders a JAI LookupTable from a LUTProperties object with same scale as length |
static LookupTableJAI |
render(LUTProperties props,
int type,
int offset,
int length,
double scale)
renders a JAI LookupTable from a LUTProperties object with the given size,
offset and length give the size of the array of the LUT, scale a logical value of
the range, that doesnt matter for linear rendering but it is important for logarithmic
rendering, the caluclation for logarithmic luts works as follows:
double d -> the index we calculate to get the color from the LUTProperties
int i -> the index (pixelvalue/intensity in the original image) for which we want a color
if( i <= offset ) d = 0; else
if( i >= offset + length ) d = 1; else
if( linear ) d = (i - offset) / length;
if( logarithmic ) d = ln ( ((i - offset) / length) * scale ) / ln(scale);
props.calcColor( d ) |
