Problem using MM_HIMETRIC mapping mode

[Tonio]

Hi,

Does MM_HIMETRIC mapping mode have maximum limits?

I'm using Polyline(...) command to plot a line to my CDC,

but when the x and y values reach approx 30000 or -30000,

the lines are no longer drawn in proper places.

Is anybody familiar with this problem?

What settings in CDC should I include?

Thanks in advance.

Hi Tonio,


you're developing under Win95/98, right? There's a limit with the GDI functions. No GDI function can take a value bigger than 32767 and smaller than -32767.

Hi,

Thanks for the info.

Now I could start researching for a work-around.

Tonio: if you find one, please let me know! I have similar problem in scrolling and zooming a gdi view, and displaying lines and arcs in a path..

Thanks!
