Usage: tsStack = TIFFStack(strFilename <, bInvert>)
A TIFFStack object behaves like a read-only memory mapped TIF file. The entire image stack is treated as a matlab tensor. Each frame of the file must have the same dimensions. Reading the image data is optimised to the extent possible; the header information is only read once.
This class uses a modified version of tiffread [1, 2] to read data. Code is included (but disabled) to use the matlab imread function, but this function returns invalid data for some TIFF formats.
Construction:
>> tsStack = TIFFStack('test.tiff'); % Construct a TIFF stack associated with a file
>> tsStack = TIFFStack('test.tiff', true); % Indicate that the image data should be inverted
tsStack =
TIFFStack handle
Properties:
bInvert: 0
strFilename: [1x9 char]
sImageInfo: [5x1 struct]
strDataClass: 'uint16'
Usage:
>> tsStack(:, :, 3); % Retrieve the 3rd frame of the stack, all planes
>> tsStack(:, :, 1, 3); % Retrieve the 3rd plane of the 1st frame
>> size(tsStack) % Find the size of the stack (rows, cols, frames, planes per pixel)
ans =
128 128 5 1
>> tsStack(4); % Linear indexing is supported
>> tsStack.bInvert = true; % Turn on data inversion
