Dear ladies and gentlemen:
How to access all the pixels of a bitmap with C#? I am working with
Delphi before. In Delphi, you can use TBitmap.Scanline property to access
all the pixels of a bitmap object. How to do this with C#? Any hints? Thank
you very much.
Best regards.

When I create a System.Drawing.Bitmap and save it as ImageType.GIF, how can I
set the transparency so that the background is transparent.
In my application, the Bitmap that I am working with has several transparent
GIFs drawn on it and the transparency of each of them works within the
bitmap, but the bitmap overall gets saved with a black background.
Any help is greatly appreciated.

I'm using a Bitmap that has a palette of 256 colors (256 bytes).
I'm taking the Bitmap data by:
System.Drawing.Imaging.BitmapData refData = myBitmap.LockBits(new
Rectangle(0, 0, bmp.Width, bmp.Height),
System.Drawing.Imaging.ImageLockMode.WriteOnly, bmp.PixelFormat);
byte* buff = refData.Scan0.ToPointer();
And on this buff I'm iterating to set its data.

I've been looking on the Internet for a way to convert a DIB to a Bitmap
without success.
Now I'm wondering if that is the approach I should be taking.
All I want to do is display the DIB or draw it into a Bitmap.
Is there a graphics method that can help?

Suppose I have
Dim bm As New Bitmap(16, 16,Imaging.PixelFormat.Format8bppIndexed)
I cannot use
Dim g As Graphics = Graphics.FromImage(bmdest)
Dim hdc As IntPtr = g.GetHdc()
as the FromImage call will fail for indexed bitmaps.

I trying to learn what a Bitmap is. Not a Managed Bitmap Object but one
that, for example, comes from the clipboard with CF_BITMAP.
I'm guessing that a CompatableBitmap is an array of indices that point to
the colors in a Palette of the display driver.
So if I get a bitmap via CF_BITMAP I need to also get a Palette off the
clipboard and realize it then display the bitmap.
I believe "Realize it" means to put it into the display driver.

I have a problem. I open bitmap file, load it to memory decrease color
palette by proceeding Euclidean distance. As a result i have image
reduced to - for example 18 colors. Once i save it -

in such a way that there will be exactly 18 colors in a file. It seems
i have problem with it...

The following creates a copy of an image. It worked fine in Visual Studio
2005, but after installing Visual Studio 2008 then opening the solution as a
..net 2.0 project, I get an error on the 'bmpOut.Palette = imageFile.Palette'
line (see below).
Anyone come across this or suggest a reason for the error?
