Rotating text on picture, and maximum size of picture

I changed a font on my picture object (and form) on which I was successfully rotating text, and now the text won't rotate. Are there only certain fonts that will rotate?

What the max size of a picture? I need to make one that's about 10 inches wide, and 100 inches tall.

-lp

The max size of a picturebox is always the screen resolution.

Code:

---

maxx = ScaleX(Screen.Height, vbTwips, vbInches)
maxy = ScaleY(Screen.Width, vbTwips, vbInches)

---

Now with screen object they are specified with twips so you convert to inches with scaleX and scaley methods.

You can't rotate the text with the standard vb methods and objects, you would have to get an activeX control or something to do that

Sure you can rotate fonts:

use the CreateFont API

This is some sample found on the net:

Use a Form with: AutoRedraw = True, BackColor = &H0&, ForeColor = &HFF& and ScaleMode = vbPixels
