Category: Data Import and Analysis > Data Import and Export

Syntax

tf = lastDirectory(t)

Description

The method acts on a Tiff object created with Tiff(filename, mode). This is the natural stop condition for a loop over every image in a multi-image file: read the current image, then call nextDirectory until lastDirectory is true.

Input arguments

t

Tiff object opened for reading.

Output arguments

tf

Logical scalar.

Example

Read every image

tag.ImageLength = 2; tag.ImageWidth = 2;
tag.Photometric = Tiff.Photometric.MinIsBlack;
tag.BitsPerSample = 8; tag.SamplesPerPixel = 1; tag.RowsPerStrip = 2;
tag.PlanarConfiguration = Tiff.PlanarConfiguration.Chunky;
w = Tiff('m.tif', 'w');
w.setTag(tag); w.write(uint8([1 2; 3 4])); w.writeDirectory();
w.setTag(tag); w.write(uint8([5 6; 7 8])); w.close();
r = Tiff('m.tif', 'r');
while true
    disp(r.read())
    if r.lastDirectory(), break, end
    r.nextDirectory();
end
r.close();
