`Tiff.isTiled`

Tells whether the current image is stored in tiles.

Category: Data Import and Analysis > Data Import and Export

Syntax

tf = isTiled(t)

Returns true for a tiled image and false for a stripped one.

Description

The method acts on a Tiff object created with Tiff(filename, mode). Use it to choose between the strip functions (numberOfStrips, readEncodedStrip) and the tile functions (numberOfTiles, readEncodedTile), because the wrong family gives an error.

Input arguments

t: Tiff object opened for reading.

Output arguments

tf: Logical scalar.

Example

Stripped and tiled files

tag.ImageLength = 8; tag.ImageWidth = 8;
tag.Photometric = Tiff.Photometric.MinIsBlack;
tag.BitsPerSample = 8; tag.SamplesPerPixel = 1; tag.RowsPerStrip = 4;
tag.PlanarConfiguration = Tiff.PlanarConfiguration.Chunky;
I = uint8(magic(8) * 3);
w = Tiff('t.tif', 'w'); w.setTag(tag); w.write(I); w.close();
tag.ImageLength = 4; tag.ImageWidth = 4;
tag.Photometric = Tiff.Photometric.MinIsBlack;
tag.BitsPerSample = 8; tag.SamplesPerPixel = 1;
tag.TileLength = 16; tag.TileWidth = 16;
tag.PlanarConfiguration = Tiff.PlanarConfiguration.Chunky;
w = Tiff('u.tif', 'w'); w.setTag(tag); w.write(uint8(magic(4))); w.close();
a = Tiff('t.tif', 'r'); b = Tiff('u.tif', 'r');
[a.isTiled() b.isTiled()]
a.close(); b.close();

Output

ans = 1×2 logical array

   0   1
