I'm trying to get my head around working with the Matrix class.
I'm doing something manually that I'd prefer to do with a transformation.
Basically I have shape objects that are responsible for drawing themselves
on a surface. The shapes all store their Positions.

Im getting this exception:

is there a way to set the output quality of a saved JPEG graphics? I
need to save some graphs (using Bitmap.Save()) into files and would
like to have more than one file format available. I know PNG is

I have a GIF which its dimensions is 200x300 pixels and it is animating fine.
But after i resize it to smaller dimensions (133x200 pixels), it doesn't
animate anymore.  
Why is it not animating ?

I draw a BitmapA, a mostly white picture with some black lines (drawn
from an array)

I use Graphics.DrawImage (...) to draw the picture to screen

I have an app that runs in the system tray. It takes an icon from the
programs resources then draws two rectangles on it and numbers... the wierd
thing is its crashing... here is the exception I am getting

GIF animations contain a frame display time that control how rapidly
the new frames are displayed during the animation. The ImageAnimator
class in GDI+ provides the UpdateFrames method which seems to do the
same thing. (I discovered a page which claimed that an internal rate

I create a 32bpp rgb bitmap in my code to write some text to it then convert
it to a monochrome. My original bitmap is 1728 W by 2261 High with a
resolution set of X= 204 and Y = 196.
After converting it to a monochrome bitmap it has the same pixels height

Apparently you cannot write directly to a monochrome bitmap so you gotta
start with an 24bpprgb and convert it to a monochrome. is that right? if
not, how can you write text to a monochrome bitmap?
I have started with writing to an rgb bitmap and am trying to convert it to

I have been working on a card game (called Uno) for past few days.
