Hello all, I'm trying to use the adimpro package to read RAW files (image). Make readins is OK! > r <- read.raw( '20171218_210956.dng', type='RAW', compress=FALSE ) > summary( r ) > ### cut the many lines... Filter pattern: GR/BG > extract.info( r ) [1] "GR/B" > To next, develop the raw file using the "develop.raw" function. But the function returns the error: > dr <- develop.raw( r ) Error in dim(mat) <- c(4, 3) : dims [product 12] do not match the length of object [0]
My suspicion is that the develop.raw function fails to get the correct Bayer's pattern. Within the develop.raw function there is a code (below) that will always return the pattern as a variable of NULL value > bayer <- switch(extract.info( r ), RGGB = 1, GRBG = 2, BGGR = 3, GBRG = 4) > bayer NULL > Is there anything to do to get around the situation? Thank you so much Cleber Borges ps.: below more details ############################## > r <- read.raw( '20171218_210956.dng', type='RAW', compress=FALSE ) > summary( r ) Image file: 20171218_210956.dng Image dimension: 3024 4032 Color space: RAW Color depth: 16bit Gamma correction: FALSE Type: None White point: D65 Range: 0 65535 EXIF-Information: Filename: 20171218_210956.dng Timestamp: Mon Dec 18 21:09:56 2017 Camera: Samsung SM-G935F DNG Version: 1.4.0.0 ISO speed: 200 Shutter: 1/24.0 sec Aperture: f/1.7 Focal length: 4.2 mm Embedded ICC profile: no Number of raw images: 1 Thumb size: 504 x 376 Full size: 4032 x 3024 Image size: 4032 x 3024 Output size: 3024 x 4032 Raw colors: 3 Filter pattern: GR/BG Daylight multipliers: 2.022219 0.916446 1.101952 Camera multipliers: 1.765517 1.000000 1.675941 0.000000 > extract.info( r ) [1] "GR/B" > > dr <- develop.raw( r ) Error in dim(mat) <- c(4, 3) : dims [product 12] do not match the length of object [0] > ### my suspection > bayer <- switch(extract.info( r ), RGGB = 1, GRBG = 2, BGGR = 3, GBRG = 4) > bayer NULL > sessionInfo() R version 3.4.2 (2017-09-28) Platform: x86_64-w64-mingw32/x64 (64-bit) Running under: Windows 7 x64 (build 7601) Service Pack 1 Matrix products: default locale: [1] LC_COLLATE=Portuguese_Brazil.1252 LC_CTYPE=Portuguese_Brazil.1252 [3] LC_MONETARY=Portuguese_Brazil.1252 LC_NUMERIC=C [5] LC_TIME=Portuguese_Brazil.1252 attached base packages: [1] grid stats graphics grDevices utils datasets methods [8] base other attached packages: [1] fields_9.0 maps_3.2.0 spam_2.1-1 dotCall64_0.9-5 [5] adimpro_0.8.2 awsMethods_1.0-4 loaded via a namespace (and not attached): [1] compiler_3.4.2 tools_3.4.2 > --- Este email foi escaneado pelo Avast antivírus. https://www.avast.com/antivirus [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
