Abstract

PURPOSE:To easily confirm a printing image and to improve the operability by displaying the printing image fully on a display screen at all times regardless of a form size. CONSTITUTION:A central processing unit 1 takes out size data on a selected form out of a form size storage circuit 9 in response to a printing image display instruction and also takes the size data on the display area of a display device 4 out of a display area size storage circuit 10. Display magnifications are calculated from both taken-out size data. For the calculation of the display magnifications, the utilization direction of the form is decided first by using the information of a form instruction. The display magnifications in a longitudinal direction are calculated from the display area size and form longitudinal size and the display magnification in a lateral direction are calculated from the display area lateral size and the form lateral size. The longitudinal display magnifications and lateral display magnifications are compared and the smaller magnifications are regarded as the display magnifications of the printing image display. Consequently, the printing image can be displayed by matching the maximum size of the form with the maximum size of the display area.

Reference numeral 8 is a storage circuit for storing a program, document data being created, parameters, etc., 9 is a paper size storage circuit for storing the sizes of various papers, and 10 is a size of an area for displaying a document or the like on the display device 4. Display area dimension storage circuit,
Reference numeral 11 denotes a character data storage circuit that stores character data (font data) used for displaying or printing a document being created, and 12 stores character data used when displaying a document being created as a print image. A contour character data storage circuit, 13 is a printing device for printing the created document on paper, 14 is a printing device control circuit for controlling the printing device 13,
An interrupt control circuit 15 controls an interrupt for interrupting the process being executed.

A procedure for creating a document in the above configuration will be described. First, use paper such as A4 size, B4
A paper size such as size is selected (block 21). Next, the character code of the sentence is sequentially input from the input device 2.
Character data storage circuit 11 according to the input character code
The corresponding character data is sequentially taken out and the characters of the input sentence are displayed on the display device 4. If there are mistakes or corrections, calibrate by instructing from input device 2 (block 2
2). Input and edit graphics such as figures and graphs as well. When the editing and proofing are completed, the input device 2 is instructed to display the print image in order to confirm whether the document is arranged on the paper as intended by the operator (block 23). In response to a print image display instruction from the input device 2, the central processing unit 1 takes out the size data of the paper selected in the block 21 from the paper size storage circuit 9 (block 24), and also acquires the size data of the display area of the display device 4. It is taken out from the display area size storage circuit 10 (block 25). A display magnification (display magnification means display area size divided by paper size) is calculated from the both dimensions taken out (block 26). To calculate the display magnification, as shown in FIG. 3, first, the direction of use of the paper (portrait or landscape) is determined from the information of the paper instruction (block 21) (block 101). The vertical display magnification is calculated from the display area vertical dimension and the paper vertical dimension (block 102), and the horizontal display magnification is calculated from the display area horizontal method and the paper horizontal dimension (block 103). The vertical display magnification and the horizontal display magnification are compared (block 104), and the smaller one is set as the display magnification for print image display (blocks 105 and 106). By doing so, the print image can be displayed by matching the maximum size of the paper with the maximum size of the display area. Next, the data of the corresponding character is retrieved from the contour character data storage circuit 12, and the character size is determined and generated based on the calculated display magnification (block 27). The graphic data is calculated and generated based on the calculated display magnification (block 28). The outline character data is generally called an outline font, and is obtained by dividing a character with an XY mesh and replacing each mesh with an approximate function, and enlarging / reducing can be arbitrarily performed by function calculation. A print image is displayed by the data generated by calculation (block 2
9). The layout is confirmed by the print image display (block 30), and if the operator's intention is met, the printing device 13 prints on the designated paper (block 31). If it does not match the operator's intention, the process goes back to the editing and proofing of block 22 and is edited again.

As described above, according to the present invention, the display magnification is variable according to the size of the paper used, so that the display area of the print image can be filled. For this reason, you can check the details on small size paper such as postcards,
In addition, even a large size sheet such as A3 can be viewed all at once, and the print image can be easily confirmed.

In the above description, the calculation of the display magnification (blocks 24 to 26) can be performed after the sheet instruction (block 21). Further, when the selection paper and the display area are limited, the paper magnification storage circuit 9 and the display area size storage circuit 10 can be omitted by previously storing the display magnification in the storage circuit.

The printing character is required to have a high character quality due to enlargement and the like, but the character quality is not a problem for a character displayed for layout confirmation such as a print image display. On the other hand, the character quality of the contour character depends on the size of the mesh described above. The finer the mesh, the higher the quality, but the more data there is and the longer it takes to generate characters. If the mesh is coarse, the character generation time is short, but the character quality is low. In this embodiment, efficient character generation is achieved by having two pieces of character data for printing, which emphasizes quality, and outline character data for checking print images, which emphasizes speed.

[0013]

According to the present invention, the print image is always displayed on the full display screen regardless of the paper size, so that the print image can be easily confirmed and the operability can be improved. .
