Predictor by default metamorph uses a horizontal

This preview shows page 2 - 4 out of 7 pages.

Predictor By default, MetaMorph uses a horizontal differencing predictor on LZW-compressed stacks. See Section 14 of the TIFF 6.0 specification for details. Custom Tags STK files use the following private tags assigned to Universal Imaging by Adobe. STK files should contain all four tags. Some versions of MetaMorph may recognize an image with only a UIC2 tag or some other subset, but for maximum compatibility, all four tags should be written: UIC1Tag Tag = 33628 (835C.H) Type = LONG (or RATIONAL) N = Number of tags If this tag exists and is of type LONG, then at the indicated offset there is a series of N pairs consisting of an ID code of size LONG and a variable-sized (ID-dependent) block of data. The possible tags and their values are defined in the “Tag ID Codes” section below. These values are used internally by the Meta Imaging Series applications, and may not be useful to other applications. To replicate the behavior of MetaMorph, this table should be read and its values stored after the table indicated by UIC4Tag is read. If the type of this tag is RATIONAL, it indicates a stack file created by an obsolete (pre-2.5) version of MetaMorph. At the indicated offset, there is a table of 2*N LONG values indicating for each plane in order: Z distance (numerator), Z distance (denominator). STK files should not be written using this tag because future versions of Meta Imaging Series may not support it. UIC2Tag Tag = 33629 (835D.H) Type = RATIONAL N = Number of planes The presence of this tag indicates that the file is a MetaMorph Stack. The stack consists of N images of size ImageWidth * ImageLength (* SamplesPerPixel for RGB images). At the indicated offset, there is a table of 6*N LONG values indicating for each plane in order: Z distance (numerator), Z distance (denominator), creation date, creation time, modification date, modification time. UIC3Tag Tag = 33630 (835E.H)

UIC4Tag Tag = 33631 (835F.H) Type = LONG N = Number of planes At the indicated offset, there is a series of pairs consisting of an ID code of size SHORT and a variable- sized (ID-dependent) block of data. Pairs should be read until an ID of 0 is encountered. The possible tags and their values are defined in the “Tag ID Codes” section below. The “AutoScale” tag never appears in this table (because its ID is used to terminate the table.) These values are used internally by the Meta Imaging Series applications, and may not be useful to other applications. It is not required that this tag be included when a stack file is saved. To replicate the behavior of MetaMorph, this table should be read and its values stored before the table indicated by UIC1Tag is read. Tag ID codes The ID codes currently defined are: ID Name Data (size is LONG except where noted) 0 AutoScale If non-zero, automatic 16-bit to 8-bit scaling is enabled for this image. (Applies only to 16-bit images.) 1 MinScale Minimum scaling value. (Applies only to 16-bit images.) 2 MaxScale Maximum scaling value. (Applies only to 16-bit images.) 3 SpatialCalibration Spatial calibration state. (0 = off, non-zero = on.) 4 XCalibration

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
