Four orientations supported: -.TP -.B ORIENTATION_TOPLEFT -origin in top-left corner, -.TP -.B ORIENTATION_TOPRIGHT -origin in top-right corner, -.TP -.B ORIENTATION_BOTLEFT -origin in bottom-left corner -and -.TP -.B ORIENTATION_BOTRIGHT -origin in bottom-right corner. -.LP -If you choose -.B ORIENTATION_BOTLEFT -result will be the same as returned by the -.IR TIFFReadRGBAImage. -.PP -Raster pixels are 8-bit packed red, green, blue, alpha samples. -The macros -.IR TIFFGetR , -.IR TIFFGetG , -.IR TIFFGetB , -and -.I TIFFGetA -should be used to access individual samples. -Images without Associated Alpha matting information have a constant -Alpha of 1.0 (255). -.PP -.I TIFFReadRGBAImage -converts non-8-bit images by scaling sample values. -Palette, grayscale, bilevel, -.SM CMYK\c -, and YCbCr images are converted to -.SM RGB -transparently. -Raster pixels are returned uncorrected by any colorimetry information -present in the directory. -.PP -The paramater -.I stopOnError -specifies how to act if an error is encountered while reading -the image. -If -.I stopOnError -is non-zero, then an error will terminate the operation; otherwise -.I TIFFReadRGBAImage -will continue processing data until all the possible data in the -image have been requested. -.SH NOTES -In C++ the -.I stopOnError -parameter defaults to 0. -.PP -Samples must be either 1, 2, 4, 8, or 16 bits. -Colorimetric samples/pixel must be either 1, 3, or 4 (i.e. -.I SamplesPerPixel -minus -.IR ExtraSamples ). -.PP -Palettte image colormaps that appear to be incorrectly written -as 8-bit values are automatically scaled to 16-bits. -.PP -.I TIFFReadRGBAImage -is just a wrapper around the more general -.IR TIFFRGBAImage (3TIFF) -facilities. -.SH "RETURN VALUES" -1 is returned if the image was successfully read and converted. -Otherwise, 0 is returned if an error was encountered and -.I stopOnError -is zero. -.SH DIAGNOSTICS -All error messages are directed to the -.IR TIFFError (3TIFF) -routine. -.PP -.BR "Sorry, can not handle %d-bit pictures" . -The image had -.I BitsPerSample -other than 1, 2, 4, 8, or 16. -.PP -.BR "Sorry, can not handle %d-channel images" . -The image had -.I SamplesPerPixel -other than 1, 3, or 4. -.PP -\fBMissing needed "PhotometricInterpretation" tag\fP. -The image did not have a tag that describes how to display -the data. -.PP -\fBNo "PhotometricInterpretation" tag, assuming RGB\fP. -The image was missing a tag that describes how to display it, -but because it has 3 or 4 samples/pixel, it is assumed to be -.SM RGB. -.PP -\fBNo "PhotometricInterpretation" tag, assuming min-is-black\fP. -The image was missing a tag that describes how to display it, -but because it has 1 sample/pixel, it is assumed to be a grayscale -or bilevel image. -.PP -.BR "No space for photometric conversion table" . -There was insufficient memory for a table used to convert -image samples to 8-bit -.SM RGB. -.PP -\fBMissing required "Colormap" tag\fP. -A Palette image did not have a required -.I Colormap -tag. -.PP -.BR "No space for tile buffer" . -There was insufficient memory to allocate an i/o buffer. -.PP -.BR "No space for strip buffer" . -There was insufficient memory to allocate an i/o buffer. -.PP -.BR "Can not handle format" . -The image has a format (combination of -.IR BitsPerSample , -.IR SamplesPerPixel , -and -.IR PhotometricInterpretation ) -that -.I TIFFReadRGBAImage -can not handle. -.PP -.BR "No space for B&W mapping table" . -There was insufficient memory to allocate a table used to map -grayscale data to -.SM RGB. -.PP -.BR "No space for Palette mapping table" . -There was insufficient memory to allocate a table used to map -data to 8-bit -.SM RGB. -.SH "SEE ALSO" -.BR TIFFOpen (3TIFF), -.BR TIFFRGBAImage (3TIFF), -.BR TIFFReadRGBAStrip (3TIFF), -.BR TIFFReadRGBATile (3TIFF), -.BR libtiff (3TIFF) -.PP -Libtiff library home page: -.BR http://www.remotesensing.org/libtiff/ -- cgit v1.2.3
