Method Detail

satisfiesThisProfile

public boolean satisfiesThisProfile(IFD ifd)

Returns true if the IFD satisfies the requirements that are common to the bilevel, grayscale, and color DLF profiles. The subclasses should call super(ifd) first, then do additional checking if it returns true. details.

Specified by:

satisfiesThisProfile in class TiffProfile

hasMinimumResolution

protected boolean hasMinimumResolution(TiffIFD tifd,
                                       double minUnit2Res,
                                       double minUnit3Res)

Checks for minimum X and Y resolution. All of the DLF profiles have similar tests for XResolution and YResolution. In all cases the values depend on the ResolutionUnit, which must be either 2 or 3.

Parameters:

tifd - The TiffIFD from which to extract the tags.

minUnit2Res - The minimum XResolution and YResolution when ResolutionUnit is 2

minUnit3Res - The minimum XResolution and YResolution when ResolutionUnit is 3
