$letter_F[^image::load[letter_F.gif]]
^letter_F.html[]
Browser will display letter F drawn by a dotted line against white background. In current directory, a file letter.gif will be created. This example uses objects of class image of two different types. The table specifies coordinates of broken line. Then, against the background created by constructor create a line is drawn through specified coordinates. Created object of class image is encoded into GIF format. Resulted object of class file is saved to disk. Afterwards, a new object of class image, based on saved file, is created. Method html will output this object to browser window.
