Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document creation apparatus which has a proportional font for printing but does not have a proportional font for display, and uses a display font having no proportional information on a display device. The present invention relates to a document creation apparatus that creates a document and displays a layout at the time of printing.

[0002]

2. Description of the Related Art There are various fonts.
Finally, there are known fonts for English and European characters called proportional fonts. This font is a font that expresses the character beautifully with different character widths for each character such as alphabetic characters. For example, the character width of W is wider than i.

Conventionally, when displaying and editing characters of a proportional font, when printing is performed, a proportional font for printing with a high resolution and a proportional font for displaying with a low resolution are prepared and displayed. There is a method in which a proportional font is prepared in advance and displayed and printed. In both cases, the layout is almost the same for display and printing.

Further, there is a method in which a proportional font for printing with a high resolution and a display font having no proportional information with a low resolution are prepared, and printing is performed with a proportional font, but display is performed with a non-proportional font. In this case, the layout is completely different between display and printing. As a remedy,
Even when printing is performed using a proportional font, but display is performed using a non-proportional font, a method is also known in which the layout between display and printing is made closer by narrowing the character spacing during display at a fixed rate.

[0005]

By the way, when a proportional font for display is prepared as described above with a low resolution as described above, it is necessary to prepare a display font of the same type as that for printing, which naturally increases costs. . Further, even when a proportional font that is used for both display and printing is prepared, the font is created so that the printing result is beautiful, so that the display quality deteriorates when displaying small characters. In particular, in a display device having a low resolution, a decrease in display quality becomes a problem.

On the other hand, in a document creation apparatus having no proportional font for display, when displaying characters or editing a document, the document cannot be displayed in a proportional font layout at the time of printing. Therefore, the state at the time of printing cannot be confirmed on the display device. In addition, even when the character spacing at the time of display is narrowed at a fixed rate and displayed, proportional display cannot be performed for each character.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances of the prior art, and an object of the present invention is to perform display according to the character width of a proportional font for printing using a non-proportional font for display.
