I'm using .net framework 1.1 and i'm doing an application that manipulate
tiff images.
Almost everything works fine.. But when Tiff images with jpeg or ojpeg
compression appears, System.Drawing.Image raises an exception.

Does anybody know how to retrieve/parse the raw bitmap bytes from a
bitmap image? In other words, excluding the header data.
Thanks so much!
Am using c# btw.

I have a question on object disposing.
 On a form I have several controls that represent
 document pages.
 Each of these page has a Bitmap and a Graphics object associated.

I would like to be able to determine the outline of the intersection of two
polygons, even in the case where more than one polygon might result.
My strategy was to create a graphicsPath object for each polygon, create a
region from each of those, then apply Region.Intersect().

I've a Object model with line rectangle text and circle. I need to get
the nearest objcet to mouse click point to select and move the object.
I've used GraphicsPath.isVisible, but if I have a rectangle and a line
in it I can't get the line.

Ok..so I was trying to follow the example on Bob's site:
(http://www.bobpowell.net/lockingbits.htm)
BitmapData bmd=bm.LockBits(new Rectangle(0, 0, 10, 10),
System.Drawing.Imaging.ImageLockMode.ReadOnly, bm.PixelFormat);

i am getting a strange effect when i use TextureBrush to fill a areal
on a graphic surface.
It seems that when the areal is not very large the filling effect is
normal but when the length

I need some code (VB or C#) that will draw a series of rectangles
(unfilled) to the screen's area, not a form or window area. I am trying
to simulate a technique I have seen when a new window opens, a series
of ever-larger rectangles are drawn to give a dynamic confirmation that

Ok..., I can honestly say that I didn't think this entirely through.
Is there a clever way through a "green screen" or some other method to
extract an object from its background.  Most likely the objects would
be pretty simple, but I need a robust way of doing this via

I sometimes got some AccessViolationException from System.Drawing.dll.
Is it a known issue
in .NET 2.0? I've never got this kind of exception in .NET 1.1.
System.AccessViolationException: Attempted to read or write protected

When drawing vertical text the result is facing the wrong way.  How do I
 rotate the result by 180 degrees?
The code:
        public void CenterVertText(Color color, Rectangle r, string str)

Basically, I want to end up comparing pixels of two different JPEG
files.  So I would like to read in the JPEF file and then access each
pixel's RGBA values.  
Is there a simple way to do this?

Hi! I have already a method in c# to open an image and load it in a picture box that I've created. It uses Bitmap class(LockBits and UnlockBits). Can someone tell me how do I draw a line over the image using the mouse? The idea is to measure the distance between the initial and ...

When I paint a form I would like to specify that a part of the form
should not be painted, to achive a transparent area of the form.
I have tried overriding the OnPaint and OnPaintBackground methods and
then tried to manipulate the graphics object's clip region to get an

I have C# appl that uses GCI+ to
draws/updates complex graphs every sec.
There is seldom small flickering.
Does somebody know if switching to GCI will
