imageinfo() - Image Processing
imageinfo creates
an Image Information tool associated with the image in the current
figure. The tool displays information about the basic attributes of
the target image in a separate figure. imageinfo gets
information about image attributes by querying the image object's CData.The following table lists the basic image information included
in the Image Information tool display. Note that the tool contains
either four or six fields, depending on the type of image.Attribute NameValue
Width (columns)Number of columns in the image
Height (rows)Number of rows in the image
ClassData type used by the image, such as uint8.Note:
For single or int16 images, imageinfo returns
a class value of double, because image objects
convert the CData of these images to double.
Image typeOne of the image types identified by the Image Processing Toolbox™ software: 'intensity' 'truecolor', 'binary',
or 'indexed'.
Minimum intensity or indexFor grayscale images, this value represents the lowest
intensity value of any pixel.For indexed images, this
value represents the lowest index value into a color map. Not
included for 'binary' or 'truecolor' images.
Maximum intensity or indexFor grayscale images, this value represents the highest
intensity value of any pixel.For indexed images, this
value represents the highest index value into a color map. Not
included for 'binary' or 'truecolor' images.
imageinfo(h) creates
an Image Information tool associated with h, where h is
a handle to a figure, axes, or image object.imageinfo(filename) creates
an Image Information tool containing image metadata from the graphics
file filename. The image does not have to be displayed
in a figure window. filename can be any file type
that has been registered with an information function in the file
formats registry, imformats, so its information
can be read by imfinfo. filename can
also be a DICOM, NITF, Interfile, or Analyze file.imageinfo(info) creates
an Image Information tool containing the image metadata in the structure info. info is
a structure returned by the functions imfinfo, dicominfo, nitfinfo interfileinfo,
or analyze75info. info can also
be a user-created structure.imageinfo(himage,filename) creates
an Image Information tool containing information about the basic attributes
of the image specified by the handle himage and
the image metadata from the graphics file filename.imageinfo(himage,info) creates
an Image Information tool containing information about the basic attributes
of the image specified by the handle himage and
the image metadata in the structure info.hfig = imageinfo(...) returns
a handle to the Image Information tool figure.
Syntax
imageinfoimageinfo(h)imageinfo(filename)imageinfo(info)imageinfo(himage,filename)imageinfo(himage,info)hfig = imageinfo(...)
Example
imageinfo('peppers.png')
h = imshow('bag.png');
info = imfinfo('bag.png');
imageinfo(h,info);
imshow('canoe.tif');
imageinfo;
