I need a easy way to store in the most compressed format a graphic path formed from multiple circles That is, eventualy, a string... I need that string to be converted back to a graphics path later... Any thoughts?  SignatureCheers, Crirus ------------------------------ If work were a good thing, the boss would take it all from you ------------------------------ A graphicsPath is not serializable as far as I know, but can be serialised to a string quite easily by recording the Points and Path types. This information is contained in a Drawing2D.PathData object set by the readonly PathData property. A graphics path can then also be recreated using byte arrays of points and types which can be recreated from a string/stream quite easily.

How about floating point values that cames from a PathPoints array of a graphics path... can I round it to integers? I have a circle as GP and I noticed there is some points like {x=234,Y=451,8421} SignatureCheers, Crirus ------------------------------ If work were a good thing, the boss would take it all from you ------------------------------ > A graphicsPath is not serializable as far as I know, but can be serialised > to a string quite easily by recording the Points and Path types.

Also, if you are writing XML use the XMLConvert class as you will hit internationalisation problems with the file being saved with , decimal place instead of .

I'm not worried about that I just want to converd all that path to a string as short as possible.. anyway, the whole graphicsPath is made by circles... and is quite anoying with that "xxx,8457"... the string have have at least double length SignatureCheers, Crirus ------------------------------ If work were a good thing, the boss would take it all from you ------------------------------ > No, I wouldnt round them - you will see slight distortions if you do eg on > an ellipse, the 4 arcs wont line up quite correctly.
