NAME

+ + + + + +
+

TIFFReadDirectory − get the contents of the +next directory in an open TIFF file

+
+ +

SYNOPSIS

+ + + + + +
+

#include <tiffio.h>

+ +

int TIFFReadDirectory(TIFF +*tif)

+
+ +

DESCRIPTION

+ + + + + +
+

Read the next directory in the specified file and +make it the current directory. Applications only need to +call TIFFReadDirectory to read multiple subfiles in a +single TIFF file— the first directory in a +file is automatically read when TIFFOpen is +called.

+
+ +

NOTES

+ + + + + +
+

If the library is compiled with +STRIPCHOP_SUPPORT enabled, then images that have a +single uncompressed strip or tile of data are automatically +treated as if they were made up of multiple strips or tiles +of approximately 8 kilobytes each. This operation is done +only in-memory; it does not alter the contents of the file. +However, the construction of the ‘‘chopped +strips’’ is visible to the application through +the number of strips [tiles] returned by +TIFFNumberOfStrips +[TIFFNumberOfTiles].

+
+ +

RETURN VALUES

+ + + + + +
+

If the next directory was successfully read, 1 is +returned. Otherwise, 0 is returned if an error was +encountered, or if there are no more directories to be +read.

+
+ +

DIAGNOSTICS

+ + + + + +
+

All error messages are directed to the +TIFFError(3TIFF) routine. All warning messages are +directed to the TIFFWarning(3TIFF) routine.

+ +

Seek error accessing TIFF directory. An error +occurred while positioning to the location of the +directory.

+ +

Wrong data type %d for field "%s". +The tag entry in the directory had an incorrect data type. +For example, an ImageDescription tag with a +SHORT data type.

+ +

TIFF directory is missing required "%s" +field. The specified tag is required to be present by +the TIFF 5.0 specification, but is missing. The +directory is (usually) unusable.

+ +

%s: Rational with zero denominator. A +directory tag has a RATIONAL value whose +denominator is zero.

+ +

Incorrect count %d for field "%s" (%lu, +expecting %lu); tag ignored. The specified tag’s +count field is bad. For example, a count other than 1 for a +SubFileType tag.

+ +

Cannot handle different per-sample values for +field "%s". The tag has SamplesPerPixel +values and they are not all the same; e.g. +BitsPerSample. The library is unable to handle images +of this sort.

+ +

Count mismatch for field "%s"; +expecting %d, got %d. The count field in a tag does not +agree with the number expected by the library. This should +never happen, so if it does, the library refuses to read the +directory.

+ +

Invalid TIFF directory; tags are not sorted in +ascending order. The directory tags are not properly +sorted as specified in the TIFF 5.0 +specification. This error is not fatal.

+ +

Ignoring unknown field with tag %d (0x%x). An +unknown tag was encountered in the directory; the library +ignores all such tags.

+ +

TIFF directory is missing requred +"ImageLength" field. The image violates the +specification by not having a necessary field. There is no +way for the library to recover from this error.

+ +

TIFF directory is missing requred +"PlanarConfig" field. The image violates the +specification by not having a necessary field. There is no +way for the library to recover from this error.

+ +

TIFF directory is missing requred +"StripOffsets" field. The image has multiple +strips, but is missing the tag that specifies the file +offset to each strip of data. There is no way for the +library to recover from this error.

+ +

TIFF directory is missing requred +"TileOffsets" field. The image has multiple +tiles, but is missing the tag that specifies the file offset +to each tile of data. There is no way for the library to +recover from this error.

+ +

TIFF directory is missing required +"StripByteCounts" field. The image has +multiple strips, but is missing the tag that specifies the +size of each strip of data. There is no way for the library +to recover from this error.

+ +

TIFF directory is missing required +"StripByteCounts" field, calculating from +imagelength. The image violates the specification by not +having a necessary field. However, when the image is +comprised of only one strip or tile, the library will +estimate the missing value based on the file size.

+ +

Bogus "StripByteCounts" field, ignoring +and calculating from imagelength. Certain vendors +violate the specification by writing zero for the +StripByteCounts tag when they want to leave the value +unspecified. If the image has a single strip, the library +will estimate the missing value based on the file +size.
