Displaying Graphics Output
The run-time graphics library routines can draw geometric features, display text, display font-based characters, and transfer images between memory and the screen.
The graphics routines provided with Intel® Visual Fortran set points, draw lines, draw text, change colors, and draw shapes such as circles, rectangles, and arcs.
This section uses the following terms:
The origin (point 0, 0) is the upper-left corner of the screen or the client area (defined user area) of the child window being written to. The x-axis and y-axis start at the origin. You can change the origin in some coordinate systems.
The horizontal direction is represented by the x-axis, increasing to the right.
The vertical direction is represented by the y-axis, increasing down.
Some graphics adapters offer a color palette that can be changed.
Some graphics adapters (VGA and SVGA) allow you to change the color that a color index refers to by providing a color value that describes a new color. The color value indicates the mix of red, green, and blue in a screen color. A color value is always an INTEGER number.
