As with the bitmap bits in a bitmap file, the bitmap data in an icon-resource file is organized in scan lines, with each byte representing one or more pixels, as defined by the color format.
As with the bitmap bits in a bitmap file, the bitmap data in a cursor-resource file is organized in scan lines, with each byte representing one or more pixels, as defined by the color format.
If the bitmap is a packed bitmap (that is, a bitmap in which the bitmap array immediately follows the BITMAPINFO header and which is referenced by a single pointer), the biClrUsed member must be set to zero or to the actual size of the color table.

 Bitmap format
Specifies that the bitmap is not compressed and that the color table consists of three double word color masks that specify the red, green, and blue components, respectively, of each pixel.
Windows supports formats for compressing bitmaps that define their colors with 8 bits per pixel and with 4 bits per pixel.
A Windows 3.0 or later DIB consists of two distinct parts: a BITMAPINFO structure, which describes the dimensions and colors of the bitmap, and an array of bytes defining the pixels of the bitmap.

 Bitmap Basics - A GDI tutorial
Bitmaps and palettes are both potentially the most usefull part and most confusing parts of the GDI subsystem to neophyte coders.
The designers of Windows decided that it would be nice to have a single way of drawing to all "things", and thus developed GDI as a universal set of routines that can be used to draw onto a screen, printer, plotter or bitmap image in memory.
Windows bitmaps are "unfortunately" rectangles so what one needs to do is mark certain areas of the bitmap as "not part of the image".

 Microsoft Windows Bitmap: Summary from the Encyclopedia of Graphics File Formats   (Site not responding. Last check: 2007-11-02)
As Windows 2.0 was being developed, support for a programmable color palette was added to both Windows and BMP, allowing user-definable color data to be stored along with the bitmap data that used it.
ColorsImportant is the number of significant colors in the palette, determined by their frequency of appearance in the bitmap data; the more frequent the occurrence of a color, the more important it is. See the explanation of this field for the Windows 3.
For example, if the BMP file holds a bitmap used as a mask (such as those used with icons and pointers), many of the pixels in the rectangular bitmap may not be used.

 Microsoft Windows Cursor and Icon
Under the Windows environment an icon is displayed by first looking through an ICO file and determining which icon bitmap best matches the number of colors and resolution of the display.
The X coordinate is relative to the cursor bitmap's left edge; the Y coordinate is relative to the cursor's top edge.
Windows then performs an action based on where the hot spot is on the display and on the current state of Windows itself.

 Systat Software Inc. - PeakFit - HTML Help
The main drawback to using a bitmap image is the significant loss of resolution that occurs when the program importing the graph stretches, shrinks, or otherwise scales the image.
Windows metafiles consist of a series of Windows graphics vector instructions which are intended to reproduce the original image.
Windows Metafiles offer superior resolution and scaling, although the program importing the image may have difficulties in properly rendering text elements such as superscripts, subscripts, and symbols in their proper positions.

 Printer Driver Development - Bitmap Driver : Windows NT Printer Driver - Bitmap Printing System
The Windows NT Printing architecture is a modular system, which allows vendors to customize the component in order to integrate their specialized components into the system.
Windows NT provides a registered callback called CBFilterGraphics that gets control of the scan lines after they have been rendered and before they are sent to the spooler.
However in systems like Windows 95 these problems are not present and hence it is possible to capture the scanlines and create a BMP in the callback directly (The name of the callback in windows95 is fBlockOut).

 efg's Graphics -- Very Large Bitmap Experiment
(Windows cannot handle very large bitmaps and the "breaking point" differs considerably among various PCs.) A secondary purpose is to explore the performance of an algorithm to count the number of unique colors in a 24-bit bitmap.
For very large bitmaps, the CPU usage is quite low and the memory usage is pegged near the top of the graph.
That is: bitmaps that resulted on Out of Resources, using (1), now with (2), they created ok. With this method i can even create 4000x4000 bitmaps on large number of computers.

 Java Tip 43: How to read 8- and 24-bit Microsoft Windows bitmaps in Java applications - Java World
Reading Microsoft Windows bitmap files in Java applications is not officially supported in the current release of Java.
The DIB format preserves explicit information unlike the plain bitmap format which is used for storage of the image in RAM.
The compressed Windows DIB format is documented in the Windows SDK.

 Windows Bitmap (BMP)
Comments: A Windows 3.0 device-independent bitmap consists of two distinct parts: a BITMAPINFO data structure that describes the dimensions and colors of the bitmap, and an array of bytes that define the pixels of the bitmap.
The bmiColors field is NULL, and each three bytes in the bitmap array represents the relative intensities of red, green, and blue, respectively, of a pixel.
If the bitmap is a 'packed' bitmap (that is, a bitmap in which the bitmap array immediately follows the BITMAPINFO header and which is referenced by a single pointer), the biClrUsed field must be set to 0 or to the actual size of the color table.

 Bitmap (Microsoft Windows Bitmap)   (Site not responding. Last check: 2007-11-02)
Bitmap is a home Windows raster format, which is used practically for all possible raster data storage.
The current format version is device independable (that means that Bitmap determines the pixel's color without reference to display device) and makes possible to record images of a different quality level (to the point of 32 bits).
After revising, the format was used to hold color and fl and white images, so it became general.

 Companion Software - Windows Metafile FAQ
A Windows metafile is a 16-bit metafile that can be used by Windows 3.x, Windows 95, 98 and Windows NT to display a picture.
Put the bitmap in a metafile along with a transparency mask bitmap and use the proper bitmap operations to apply the mask to the bitmap before displaying it on the screen, or
Convert the bitmap to a metafile by "vectorizing" it (as described above) and then delete all objects of the background color.

 Converting a Windows bitmap font to an *nix compatible font | asitis.org
Converting a Windows bitmap font to an *nix compatible font
Because every character has the same width, they can become very small in size and still be legible, thus allowing the programmer to view a significant amount of code at once.
Bitmap fonts in Windows are compiled in the binary FON format.

 Dr. Dobb's | Skinning in MFC, Part 4 | February 21, 2003
Most likely this bitmap is to be used as the background of the window and the HRGN is used to describe the shape of the window.
This results in the window looking exactly like the bitmap itself and is one of the standard aspects of skinning.
As with dragging the window around the desktop, this is something you have to do yourself (you probably notice by this point that skinning is a lot of work since many of the default window behaviors you take for granted aren't available).

 ProFont for Windows, for Macintosh, for Linux
The Windows file has some versions that are not in contained in the Mac file.
I found no way to convert Macintosh or Windows bitmap fonts to the Atari.fnt font file format (and yes, there are still Atarians working with much better software than you'll probably guess), but I found a font called ProFontJB, made by Jens Brüggemann, which comes close.
And there's a new Mac bitmap version which includes a Euro characters which is quite ugly at some sizes, originally presented here and by me...
