W1: readimage(gethome + "data\mandrill.bmp")
saveimage(getmiscpath(1, 1) + "mandrill.png", w1, 1);
W2: readimage(getmiscpath(1, 1) + "mandrill.png")
W1 reads and displays the bitmap image file "mandrill.bmp".
SAVEIMAGE saves the image as a PNG file as determined by the "png" file extension. The existing file, if any, is overwritten.
W2 loads the PNG file. The image is the same as W1.
W3: spline2(randn(10), 10);setplottype(3);turbo
saveimage(getmiscpath(1, 1) + "density.png", w3, 1);
W4: readimage(getmiscpath(1, 1) + "density.png")
W3 creates a density plot by 2D cubic spline interpolation of a 10x10 random matrix, The resulting image is 91x91 and shaded using the TURBO color scheme.
SAVEIMAGE saves the density plot as a JPG file. The existing file if any, is overwritten.
W4 loads the JPG file. The image is the same as W3.
SAVEIMAGE saves an image from a window or series to a variety of image file formats.
By default, the type of saved image is determined by the filename extension. Current supported extensions include BMP, GIF, JPG, PNG and TIF.
See READIMAGE to load an image file.
