- pixel - The smallest screen element that
can be controlled by a computer with respect to light intensity and color. The
higher the number of pixels the better the image quality displayed on the screen.
- applet parameters - Applet parameters allow the
user to customize the applet's configuration. This is done by defining
the applet param tag along with values for name and value.
For example, the Animator
Applet allows you determine the image that first appears while the applet is loading
<applet code = "Animator.class" width = 300 length = 200 >
.
<param = "startup" value = "first.gif" >
<param name = ..... value = ........ >
.
</applet>
- gif - GIF: Graphics Interface Format. The file
name extension used for a Bitmap format to transmit graphics.
- Bitmap - An image stored pixel by pixel, where every pixel is
represented individually in memory. The term 'bitmap' is used because it is
possible for the state ('on' or 'off') of a single bit to represent the state
of a corresponding pixel. Because Graphics generally contain a large number of
pixels, each of which has not only position but colour and intensity, bitmap
storage uses a large amount of memory or disk space. However, unlike Vector
graphics it needs no mathematical calculations to generate images, and is
preferred for images of subtlety and detail. Also, bitmap is the only
practical way of storing scanned-in digitised graphics.
- class - The basic building block of Java. It is a template that
describes the data and behavior associated with instances or objects of that
class.
