About resolution in bitmap images - Resolution is the number of dots or pixels per linear unit used to reproduce artwork and images. Output devices display images as groups of pixels. The resolution of vector graphics, such as Illustrator artwork, depends on the device used to display the artwork. The resolution of bitmap images, such as digital photographs, depends on both the display device and the inherent resolution of the bitmap image.
Accessing bitmap WWW graphics - This research project on making accessible bit map graphics accessible was started in 1997 and has now ended because of the emergence of the far superior accessibility of Scalable Vector Graphics (SVG). However we learned a great deal from this bit map graphics work and retain this description as an archive of a successful research enroute to a more successful product based on something better than bit mapped graphics.
Basics of Raster Imagery - Most, if not all, of the images you see on the Internet are raster images. Raster images are composed of small points of color data called pixels (short for "picture element"). The advantage of raster images is the ability to represent complex shapes and colors in a relatively small file format. Photographs, for example, are represented using raster images.
Beginners Guide to Bitmaps - This document is to serve as an elementary introduction to bitmaps as they are used in computer graphics.
Bitmap images: conversion to SVG - Here I show how to insert bitmaps into SVG files and above all, how to export them to the SVG format.
Bitmap Graphics - Bitmap theory and the pitfalls associated with colourmapped bitmaps
Bitmap Graphics Demonstrated in Ray Tracing Algorithm Code Snippet - Why Use Bitmaps? - Suppose that ten seconds are required to generate the pixel data for the test rendering. Now imagine that while using pswraps a rendering takes a total of twenty seconds. While using bitmaps the same rendering takes a total of eleven seconds. The test would suggest a speed increase of roughly 2X when in reality the speed increase is more on the order of 10X (it took one second instead of ten to draw the image data to the screen).
Bitmap Graphics Tutorial - Part 3 of a Series on Graphics Files - What is a bitmap? In simplest terms, a bitmap is a rectangular picture. Computers recognize things as collections of bits, so to a computer, a bitmap is a rectangular grid of pixels.
Bitmaps - A bitmap is a graphical object used to create, manipulate (scale, scroll, rotate, and paint), and store images as files on a disk. This overview describes the bitmap classes and bitmap operations.
BMP Format - this document describes the microsoft windows and ibm os/2 picture bitmap files, called bitmaps or bmp files. most of the descriptions of the bmp file concentrate on the microsoft windows bmp structures like bmpinfoheader and bmpcoreinfo , but only a few describe the file contents on byte level. this information is therefor only intended to be used in applications where direct reading and writing of a bmp file is required.
Case study: colour spaces for bitmap graphics - The design of a canonical intermediate structure is fundamental to Migration on Request. While it needs to be broad enough to represent a cross section of different formats (within a particular genre, such as word processing or vector graphics) it should not duplicate data or have multiple methods of representation that cause redundancy and reversible migration problems. It is crucial that the structure is extensible to allow for future developments; assumptions should not lead to restrictions.
Characteristics of Bitmapped Graphics - A bitmap is a map of bits (pieces of computer information) describing all the points in a rectangular grid of dots ("picture elements" or "pixels".) Photographic images are usually in bitmap form. Bitmaps are also refered to as raster images.
Computer Art Lessons - Anti-Aliasing and Resampling Artwork - Part 1 - I'd planned to discuss the fundamental differences between vector and bitmap graphics this month, but along the way I got a little carried away with one of the fundamentals of bitmap images: anti-aliasing. It's a fair enough topic for beginners and it's not a bad read for those of us who've been around the pixel once or twice.
Computer Art Lessons - Anti-Aliasing and Resampling Artwork - Part 2 - In the first part of this series, you took a look at anti-aliasing from the standpoint of how it works and what it can mean to the refinement of your artwork. This month, let's examine exactly how anti-aliasing works (hint: it's interpolation).
Convert raster images to raster CGM - CGM is commonly thought of as a vector format, but it also includes support for raster. Convert: Image to CGM re-encodes over 50 different raster formats into raster CGM. It is NOT a raster to vector converter, and you will not be able to edit components after conversion.
(Don't) Print That GIF - There Are Better Choices of Graphic Formats for Printing - Are you one of the hundreds of people who've wondered about why Web graphics that look great in a Web browser don't look so good when printed?
File Formats for Teaching and Learning: Raster Images Part I - Overview - Raster Image File Formats - Raster images (aka bitmaps) are made up of grids of pixels. Typically they represent acquired images rather than computer generated graphics. Some of the most commonly used non-proprietary file formats are TIFF and JPEG for print, and JPEG, PNG and GIF for screen use. TIFF, GIF and PNG typically offer lossless compression while JPEG sacrifices image detail and is known as lossy. Uncompressed TIFF files are a widely recognised file format, well suited to archiving images.
Filling regions in binary raster images: A graph-theoretic approach - Source International Conference on Computer Graphics and Interactive Techniques
Flash Bitmaps - Although Flash is a tool designed for vector illustration (which is created mathematically), there are also raster graphics, or (more commonly known) bitmap graphics.
Graphics File Types - Bitmaps - Many of the images that you use in school are bitmap. A bitmap image is one where it is made up of lots of tiny dots or pixels of various colours.
How to Rotate Raster Images - Graphics Editing Tip - You can minimize pixel distortion - It is generally not a good idea to rotate raster images (bitmaps, such as TIFF, PCX, BMP, and GIF) at anything other than 90 degree increments because it causes pixel distortion.
Introduction to Bitmapped Graphics - The best example of a bitmap graphic image is a photo. When scanned into a computer, it becomes thousands of individual dots of color called "pixels" (= picture elements). This image contains 25,600 pixels (160 wide x 160 high).
Importing Bitmap Graphics into Flash - Even though Flash is a vector-based application, you can still import and work with bitmap graphics. Once a graphic is inside Flash, it becomes an element that is editable. You can animate the bitmap, skew it, scale it, distort it, break it apart, and even convert it into vectors.
Intro to Macromedia Flash: Lesson 2 - Importing Graphics: When to Bring in Bitmaps - Bitmaps in a Vector Environment - Because Flash uses primarily vector graphics in its application, it's sometimes tough to work with bitmap graphics like JPEG, GIF, or PNG files. It isn't impossible, though, and Flash contains a lot of useful ways to incorporate such files into your Flash movie (and to optimize the results).
Intermediate Flash and Working with Bitmaps (PDF) - Working With Bitmaps Bitmap graphics, a.k.a. raster graphics, are stored in the computer as a series of values, witheach pixel taking a set amount of memory. Because each pixel is defined individually, this format is great for photographic images with complex details. Keep in mind that bitmap graphics generally have larger file sizes than vector graphics

Raster Images: Scanned, Computer Generated, and Printed - This image (a laser printed page) is a raster of pixels. A raster is a grid or array of pixels (PICture ELements) or pels (Picture ELements) that reproduce an image.
Raster Quality Checklist - The most common reason for poor vectorization results is a poor quality raster image. Scan2CAD can only give results as good as the raster image you give it to vectorize. Nowhere is the saying "Garbage In, Garbage Out" truer than in raster to vector conversion.
Rendering to Raster Image Files - One of the most common tasks performed by users of VMD is producing images which can be loaded into other programs or used in printed documents, posters, slides, and transparencies. The Render form provides a simple mechanism for generating image files from snapshots of the VMD graphics window and through the use of external rendering and ray tracing programs.
Resampling Bitmaps with Alpha - If you want to change the size of a bitmap, you quickly find that standard techniques such as GDI's StretchBlt aren't particularly good and the result is usually very pixelated.
Resolution - Printing from Bitmaps (Pixels) - Scanning, Painting or Exporting a new Image without first establishing the various ways the bitmap is to be printed will often waste many hours of work. What resolution to use?, must be decided by knowing which will be the highest quality device used to output the image, immediately AND possibly sometime in the future.
Resizing of Bitmaps - Screen captured images are always bitmaps. And resizing bitmap images will almost always result in reduced viewing quality. Vectorised images don't have that problem, but that's another story.
Turning Bitmaps Into Vector Graphics - Here's a little known fact that quite a few print designers and illustrators, as well as all you Web designers and animators, will love to know: the best tool for converting bitmap graphics into vectors is Macromedia's Flash 3. What? Yes, that's right
Understanding Bitmaps - When you scan an image, e.g. a photograph, it is digitized or converted into a series of discrete units called picture elements or pixels. Each pixel has its own color. Such digitized images are easy for a computer to manipulate
Working with Bitmaps in Flash - Working with Bitmaps - In this section you'll learn more about using bitmapped graphics as individual elements. For instance, you can very easily use a bitmap as a fill color for another graphic.
