Create Image or Bitmap from ARGB value

[Steve Amey]

Hi all

I have an ARGB value for a Colour (Eg. -65536. The value was retrieved by
using the Color.ToArgb method), is there any way that I can create a
System.Drawing.Image or a System.Drawing.Bitmap from that value?

Regards,
Steve

"From this value" is a bit vague. Do you mean you would like to create a
32x32 bitmap file that is filled with this particular color or something
similar...

If yes you may want to post the exact point that causes a problem (creating,
filling, saving etc...)

The doc for the System.Drawing namespace is at :

Hi Patrice

Sorry if I'm being vague. I want to create a Bitmap or Image that is the
exact colour of the Argb values I have, then assign that Image or Bitmap to
a column in a Grid Control I have. I don't need to actually save the Image
anywhere, it will only exist while the application is running.

The problem is I don't know how to create a Bitmap or Image object that will
display the Colour of the Argb values.

Regards,
Steve.

You could create a bitmap using :

Dim b As New Bitmap(32, 32)
Dim g As Graphics = Graphics.FromImage(b)

g.FillRectangle(New SolidBrush(Color.Blue), 0, 0, 32, 32)

g.Dispose()



Just use the color you want instead of Color.Blue. Not sure but depending on
the grid you are using you could also likely just alter the cell color
background (if possible) instead of using a colored bitmap.



Note that having the compoent is useless. you can use the Color object you
have...

Lovely. Thank you for your help Patrice )

I could've changed the Backcolor of the Cell but I wanted more control over
the size of the image so that it doesn't fill the entire cell, changing the
size of the Bitmap and assigning it to the column looks really good.
