Member Enumeration Documentation

RAW decoding Interpolation methods.

Bilinear: use high-speed but low-quality bilinear interpolation (default - for slow computer). In this method, the red value of a non-red pixel is computed as the average of the adjacent red pixels, and similar for blue and green. VNG: use Variable Number of Gradients interpolation. This method computes gradients near the pixel of interest and uses the lower gradients (representing smoother and more similar parts of the image) to make an estimate. PPG: use Patterned Pixel Grouping interpolation. Pixel Grouping uses assumptions about natural scenery in making estimates. It has fewer color artifacts on natural images than the Variable Number of Gradients method. AHD: use Adaptive Homogeneity-Directed interpolation. This method selects the direction of interpolation so as to maximize a homogeneity metric, thus typically minimizing color artifacts. DCB: DCB interpolation (see http://www.linuxphoto.org/html/dcb.html for details)

NOTE: from GPL2/GPL3 demosaic packs - will not work with libraw>=0.19

PL_AHD: modified AHD interpolation (see https://sites.google.com/site/demosaicalgorithms/modified-dcraw for details). AFD: demosaicing through 5 pass median filter from PerfectRaw project. VCD: VCD interpolation. VCD_AHD: mixed demosaicing between VCD and AHD. LMMSE: LMMSE interpolation from PerfectRaw. AMAZE: AMaZE interpolation and color aberration removal from RawTherapee project.

NOTE: for libraw>=0.19 only

DHT: DHT interpolation. AAHD: Enhanced Adaptive AHD interpolation.

Definition at line 66 of file rawdecodingsettings.h.

Input color profile used to decoded image NOINPUTCS: No input color profile.

EMBEDDED: Use the camera profile embedded in RAW file if exist. CUSTOMINPUTCS: Use a custom input color space profile.

Definition at line 120 of file rawdecodingsettings.h.

Noise Reduction method to apply before demosaicing NONR: No noise reduction.

WAVELETSNR: wavelets correction to erase noise while preserving real detail. It's applied after interpolation. FBDDNR: Fake Before Demosaicing Denoising noise reduction. It's applied before interpolation. LINENR: CFA Line Denoise. It's applied after interpolation. IMPULSENR: Impulse Denoise. It's applied after interpolation.

Definition at line 106 of file rawdecodingsettings.h.

Output RGB color space used to decoded image RAWCOLOR: No output color profile (Linear RAW).

SRGB: Use standard sRGB color space. ADOBERGB: Use standard Adobe RGB color space. WIDEGAMMUT: Use standard RGB Wide Gamut color space. PROPHOTO: Use standard RGB Pro Photo color space. CUSTOMOUTPUTCS: Use a custom workspace color profile.

Definition at line 135 of file rawdecodingsettings.h.

White balances alternatives NONE: no white balance used : reverts to standard daylight D65 WB.

CAMERA: Use the camera embedded WB if available. Reverts to NONE if not. AUTO: Averages an auto WB on the entire image. CUSTOM: Let use set its own temperature and green factor (later converted to RGBG factors). AERA: Let use an area from image to average white balance (see whiteBalanceArea for details).
