JPS63100872A - Hard copy system for display screen - Google Patents

Abstract

PURPOSE:To obtain the hard copy of an optional display screen by transferring image information from a frame memory storing it, for example to other image memory and applying magnification processing at a prescribed magnification depending on paper size and print resolution or the like and printing out the result. CONSTITUTION:In desiring the print out of the same display image information as the display screen A of display image information displayed on the screen, a transfer processing 2 transfers the display image information shown in a window W on a frame memory B to an image memory C. Further, the magnification E is calculated in matching with the output image size depending on the print resolution of a printer and the size of print output paper and expanded as output image information X in the image memory C while being expanded by the magnification. The expanded output image is printed out onto printer paper and the hard copy of the display pattern is realized as the printing result D.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printing means in an electronic filing system, and relates to a hard copy method for a display screen in which image information displayed on the screen is directly copied in hard copy. Here, the image information includes characters, figures, photographs, and other image information.

〔overview〕

The present invention provides a hard copy method of a display screen in an electronic filing system in which a hard copy of image information displayed on a display screen is taken. By enlarging the image at a predetermined magnification determined by paper size, printing resolution, etc., and printing it out, it is possible to make a hard copy of any display screen.

(Prior Art) Fig. 2 is an explanatory diagram showing an example of a hard copy method of the display screen of a conventional electronic filing system. The registered image information is developed into the original size area a and reduced area b in the memory area of memory B'.In display processing 1 for displaying the screen, reduced area b is used to display the entire image. However, in order to display an enlarged image, a window W is set on the original size area a to be displayed on the screen, and image information of the entire original size area a is used during printout processing 3. Therefore, When printing out an enlarged image while displaying it, the display screen A and the printed result will not be the same.

[Problem that the invention seeks to solve]

In the hard copy method of the display screen of the conventional electronic filing system described above, there is only one memory space used for manipulating image information, as shown by memory B' in FIG. In order to actually enlarge the image information set in window W to the output image size, even though the system user recognizes that the image information is enlarged by moving window W on area a. Because the work area cannot be prepared due to memory capacity limitations, the registered image information, which is the image information of the original size area a corresponding to the output image size, is always printed out and is shown on the enlarged display screen A in Figure 2. There was a drawback that it was not possible to make a hard copy of the display image information that was displayed.

SUMMARY OF THE INVENTION An object of the present invention is to provide a hard copy system for display screens that can make a hard copy of any display screen by eliminating the above-mentioned drawbacks.

[Means for solving problems]

The present invention provides a display hard copy method in an electronic filing system that takes a hard copy of image information displayed on a display screen, in which the image information is transferred from a memory area in which it is stored to another memory area, and a predetermined It is characterized by performing enlargement processing at a magnification and printing it out.

[Effect]

For example, among the image information developed on the frame memory as memory, only the display image information displayed on the screen is transferred to a separate image memory,
For example, a magnification is set according to the print output paper size and the printing resolution of the printer, and the display image information displayed on the screen is printed out by enlarging the display image information according to the magnification.

Therefore, it is possible to make a clear hard copy of any display screen in an appropriate size, regardless of whether the display screen is partially enlarged.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an explanatory diagram showing one embodiment of the present invention. In the present invention, two types of memories are set up that can manipulate image information. One is frame memory B in FIG. 1, and the other is image memory C in FIG. Image information of a portion of frame memory B where window W is set is displayed as display screen A on the screen. Therefore, when this electronic filing system user performs display processing 1 such as enlarged display on display screen A, the same display image information as the new display screen A displayed as a result of the processing will be displayed on frame memory B. It exists in the set part of window W.

If you want to print out the same display image information as the display screen A of the display image information displayed on the screen, transfer processing 2 transfers the display image information shown in the window W on the frame memory B to the image memory C.
Transfer to. Further, a magnification E is calculated to match the output image size based on the printing resolution of the printer and the size of the printout paper, and the image is enlarged by the magnification and developed as output image information X on the image memory C.

In this case, the magnification E is determined as follows.

M and M' are the number of display dots on the display, P and P' are the printer output paper size, N and N' are the number of image dots corresponding to the printer output paper size P and P', the display resolution dl of the display, and the printer's printing. When the resolution is d2, the magnification E is calculated using the following formula (1)
, (2).

M:N=M':N'=E':256
・−・−・・−(1) (E' is a natural number) d.

Then, as shown in printout process 3, the output image information developed in the image memory C is printed out onto printer paper using a known technique, and a hard copy of the display screen is realized as the print result.

Note that in the above explanation, there are two separate memories, a frame memory and an image memory, but this means that in one memory device, the memory area may be divided into a frame memory area and an image memory area. .

Further, in the above example, a printer outputs a hard copy of text, but the present invention can also be implemented when an XY recorder, a laser printer, or the like is used to obtain a drawing or photograph as an output bird copy.

〔Effect of the invention〕

As explained above, the present invention transfers the display image information actually displayed on the screen out of the registered image information to the image memory, and then transfers the display image information actually displayed on the screen to the image memory, and then transfers the display image information that is actually displayed on the screen to the image memory, By enlarging the screen at a certain magnification, it is possible to make a hard copy of any display screen.
