Bitmap images (development): Difference between revisions

Revision as of 08:33, 13 August 2007

There is a requirement to let mind maps contain bitmap images. Word processors store their bitmap images in their files.

The images shall be stored at as binary data in a node, like

<node TYPE="image" BINARY="x4543edvc...45ert"/>

Upon creation of node view, temporary file shall be created, and HTML viewer of the JLabel shall point to that file.

Upon editing, external image editor shall be opened to edit the temporary file, like Gimp.

TODO: how FreeMind applet shall deal with these images.
