Graphics and storage

[Clyde]

Hi all...

Is it possible with VB to store shapes and colours (e.g a red circle, a blue
triangle...)in a database (preferably on access)and make an interface with
VB to read this data and represent the corresponding shape and colour graphically?

If so. In what direction do I have to search for more info.?

Thankx

Sure, all vector shapes can be represented as a series of coordinates then
their fill/line styles and colours as a series of other fields. You could
quite easily take an array of points and CopyMemory() then into a string or
something to store in a database (If you're worried about storage size) If
not then simply make a 1 to many relationship from each shape to a table of
coordinates, how you store it is really up to you.
Then to draw it you simply use the API graphics routines such as
MoveToEx()/LineTo() for lines, Rectangle() for rectangles Ellipse() for
circles/ellipses, Polygon() for polygons, triangles, hexagons etc. Colours
and styles are changed through using the API pen and brush objects and
there's a library on my page that encapsulates their usage called APIDraw.
Hope this helps,

Mike

You may give a chance to the enhanced metafile format files...
(Which is some kind of "interpreted" GDI instructions)
