Описание свойств

Monochrome1 публичное статическое свойство

Pixel data represent a single monochrome image plane. The minimum sample value is intended to be displayed as white after any VOI gray scale transformations have been performed. See PS 3.4. This value may be used only when Samples per Pixel (0028,0002) has a value of 1.

Monochrome2 публичное статическое свойство

Pixel data represent a single monochrome image plane. The minimum sample value is intended to be displayed as black after any VOI gray scale transformations have been performed. See PS 3.4. This value may be used only when Samples per Pixel (0028,0002) has a value of 1.

PaletteColor публичное статическое свойство

Pixel data describe a color image with a single sample per pixel (single image plane). The pixel value is used as an index into each of the Red, Blue, and Green Palette Color Lookup Tables (0028,1101-1103&1201-1203). This value may be used only when Samples per Pixel (0028,0002) has a value of 1. When the Photometric Interpretation is Palette Color; Red, Blue, and Green Palette Color Lookup Tables shall be present.

Rgb публичное статическое свойство

Pixel data represent a color image described by red, green, and blue image planes. The minimum sample value for each color plane represents minimum intensity of the color. This value may be used only when Samples per Pixel (0028,0002) has a value of 3.

YbrFull публичное статическое свойство

Pixel data represent a color image described by one luminance (Y) and two chrominance planes (Cb and Cr). This photometric interpretation may be used only when Samples per Pixel (0028,0002) has a value of 3. Black is represented by Y equal to zero. The absence of color is represented by both Cb and Cr values equal to half full scale. In the case where Bits Allocated (0028,0100) has a value of 8 then the following equations convert between RGB and YCBCR Photometric Interpretation: Y = + .2990R + .5870G + .1140B Cb = - .1687R - .3313G + .5000B + 128 Cr = + .5000R - .4187G - .0813B + 128

YbrFull422 публичное статическое свойство

The same as YBR_FULL except that the Cb and Cr values are sampled horizontally at half the Y rate and as a result there are half as many Cb and Cr values as Y values. This Photometric Interpretation is only allowed with Planar Configuration (0028,0006) equal to 0. Two Y values shall be stored followed by one Cb and one Cr value. The Cb and Cr values shall be sampled at the location of the first of the two Y values. For each Row of Pixels, the first Cb and Cr samples shall be at the location of the first Y sample. The next Cb and Cr samples shall be at the location of the third Y sample etc.

YbrIct публичное статическое свойство

Pixel data represent a color image described by one luminance (Y) and two chrominance planes (Cb and Cr). This photometric interpretation may be used only when Samples per Pixel (0028,0002) has a value of 3. Black is represented by Y equal to zero. The absence of color is represented by both Cb and Cr values equal to zero. Regardless of the value of Bits Allocated (0028,0100), the following equations convert between RGB and YCbCr Photometric Interpretation: Y = + .29900R + .58700G + .11400B Cb = - .16875R - .33126G + .50000B Cr = + .50000R - .41869G - .08131B

YbrPartial420 публичное статическое свойство

The same as YBR_PARTIAL_422 except that the Cb and Cr values are sampled horizontally and vertically at half the Y rate and as a result there are four times less Cb and Cr values than Y values, versus twice less for YBR_PARTIAL_422. This Photometric Interpretation is only allowed with Planar Configuration (0028,0006) equal to 0. The Cb and Cr values shall be sampled at the location of the first of the two Y values. For the first Row of Pixels (etc.), the first Cb and Cr samples shall be at the location of the first Y sample. The next Cb and Cr samples shall be at the location of the third Y sample etc. The next Rows of Pixels containing Cb and Cr samples (at the same locations than for the first Row) will be the third etc.

YbrPartial422 публичное статическое свойство

The same as YBR_FULL_422 except that: black corresponds to Y = 16 Y is restricted to 220 levels (i.e. the maximum value is 235) Cb and Cr each has a minimum value of 16 Cb and Cr are restricted to 225 levels (i.e. the maximum value is 240) lack of color is represented by Cb and Cr equal to 128 In the case where Bits Allocated (0028,0100) has value of 8 then the following equations convert between RGB and YBR_PARTIAL_422 Photometric Interpretation: Y = + .2568R + .5041G + .0979B + 16 Cb = - .1482R - .2910G + .4392B + 128 Cr = + .4392R - .3678G - .0714B + 128

YbrRct публичное статическое свойство

Pixel data represent a color image described by one luminance (Y) and two chrominance planes (Cb and Cr). This photometric interpretation may be used only when Samples per Pixel (0028,0002) has a value of 3. Black is represented by Y equal to zero. The absence of color is represented by both Cb and Cr values equal to zero. Regardless of the value of Bits Allocated (0028,0100), the following equations convert between RGB and YBR_RCT Photometric Interpretation: Y = floor((R + 2G +B) / 4) Cb = B - G Cr = R - G The following equations convert between YBR_RCT and RGB Photometric Interpretation: R = Cr + G G = Y – floor((Cb + Cr) / 4) B = Cb + G
