  edu.harvard.hul.ois.jhove.module.tiff.TiffProfile
      edu.harvard.hul.ois.jhove.module.tiff.TiffFXBase

Direct Known Subclasses:

TiffProfileFXC, TiffProfileFXF, TiffProfileFXJ, TiffProfileFXL, TiffProfileFXM, TiffProfileFXS

public abstract class TiffFXBase
extends TiffProfile

Base class for all profiles under TIFF/FX. All TIFF/FX profiles should call TiffFXBase.satisfiesClass to establish that common requirements are met.

Method Detail

satisfiesClass

protected boolean satisfiesClass(TiffIFD ifd)

Test for common requirements of all Tiff/FX profiles. Subclasses should call satisfiesClass() from their satisfiesThisProfile() method to avoid redundant code. If this method returns false, the IFD does not meet the requirements of any TIFF/FX profile. Calling this also guarantees that the image length, image width, bits per sample, X resolution (sampling frequency), Y resolution and page number values are non-null objects.

perCMtoPerInch

protected int perCMtoPerInch(int res)

Convert a units/cm value to a units/inch value. For expected values, we use a table lookup to avoid rounding problems. If a value isn't in the table, we do a rounded conversion.
