Image Justification

Figure 37:  Image Area

The Image Area is the screen area that is available for the browser to render that particular image. If an image overflows the image area, the graphic engine expands to the right and downward until the image completes or truncates the image at the image area border (screen glass). The hspace and vspace values define the Image Area.

The Application Area starts at pixel 17 and ends at pixel 313, making the width 297. The numbers in the bullet list that follows are relative positions within the 0 to 296 pixel range. Images can be rendered starting at pixel 0 relative to the Application Area as follows:

• A 0 (zero) pixel border on the left and right sides of all images displayed, as well as on top of any image displayed. The border area is empty.
• A 0 (zero) pixel border at the bottom.
• No 0 (zero) pixel border on the top of the remaining lines of images that span multiple lines.

Left-justified images begin at pixel 0. Center-justified images center at pixel 150. Right-justified images end at pixel 296. All positions are relative to the Application Area.

The default values for hspace and vspace are 0 pixels. This default value is honored only if the authors have not specified their own hspace and vspace values.
