Hi all,
I am using the color dialog box to select a colour
to print with. However, the
e.Graphics.Draw String
method uses Brushes.Black, not Color.Black.
How do I convert from Brushes to Colors and back
again so that my program will run correctly?
Any help much appreciated,
Jason. 5 3492
You could try something like:
'Determine the font to use
Dim MyFont As New Font(Drawing.Fo ntFamily.Generi cSansSerif, 8.0F,
FontStyle.Bold, GraphicsUnit.Po int, 0, False)
'Determine which color you are going to use
Dim MyColor As Color = Color.Black
'Create a brush based on the color
Dim MyBrush As New SolidBrush(MyCo lor)
'Draw the string
e.Graphics.Draw String("Test String", MyFont, MyBrush, 0, 0)
'Dispose of the brush object.
MyBrush.Dispose
'Dispose of the font object
MyFont.Dispose
With this method, you don't need to return the color from the brush since
you have already defined the color before creating the brush. You simply
access MyColor to determine which color the text was drawn in.
Hope this helps,
Jody

Color -> Brush:

Dim b As New Brush(Color.Bla ck)

b.Dispose()

Why do you need the reverse "conversion "?

Thanks for the help with the color to brush cast.
Using
dim myBRush as new SoldiBrush(myLa bels.Colour)
did the trick, but
Dim myBrush As New Brush(Color.Bla ck)
did not!
myLabels is a class and Colour is a shared property that
stores its value in a private shared field that is defined as
Color.
Do you have any ideas when one method should work
and the other not? I get a message that says
'New' cannot be used on a class that is declared 'MustInherit'.
I have the program segment working now but it would be
useful to understand what the difference is between your
two suggestions!
Thanks,
Jason.

Brush is an abstract class, i.e. you can not create an instance. You can
only create an instance of classes derived from Brush, like SolidBrush.

I have a bitmap and make the color transparent;
mybitmap.MakeTransparent(Color.Black)
When I save it as a Icon, the black color is not transparent. However, if I
save it as a bitmap then display it using windows explorer, the black color
is in fact transparent. Could it be that the bitmap is not an alpha bitmap
that causes the icon to not have the black color transparent?

I guess this must be a well-known issue that I just hit my head on.
Color.Equals doesn't apply the usual equality test.
For example:
using (g = Graphics.FromImage(bmp))
g.FillRectangle(Brushes.Black, new Rectangle(Point.Empty, bmp.Size));
One might expect that for any (x, y) inside the image bounds,
