Can be done.

FIG. 4 is a diagram for explaining the flow of the enlarged image capturing process.
The form printing software 33 transmits a message for instructing the enlarged capture software 32 to perform screen capture (hereinafter referred to as a capture request) (S401).

When receiving the capture request, the enlargement capture software 32 performs the following processing on each of the divided images obtained by dividing the distribution diagram into two parts vertically and horizontally and divided into four parts.
The enlarged capture software 32 controls the distribution diagram display software 31 to enlarge the partial image (S402), and causes the distribution diagram display software 31 to enlarge and display the divided images of the distribution diagram (S403). ) (Image enlargement display section).

  5 to 7 show examples of screens displayed on the distribution diagram display software 31 under the control of the enlarged capture software 32. FIG. FIG. 5 is an example of an entire distribution diagram image to be captured, which is displayed by the distribution diagram display software 31 before being controlled by the enlarged capture software 32. The enlarged capture software 32 distributes the entire distribution diagram to be captured shown in FIG. 5 so that each of the divided images A to D divided into four as shown in FIG. 6 is enlarged to the same size as the entire image. The figure software 31 is controlled. For example, as shown in FIG. 7, the divided image A is enlarged and displayed as a divided image A ′. Thereby, a more detailed image is displayed on the display 106. The distribution diagram display software 31 is controlled, for example, when the enlarged capture software 32 transmits a control command to the distribution diagram display software 31.

  When the divided image is enlarged and displayed by the distribution diagram display software 31, the enlarged capture software 32 transmits a capture request to the operating system 21 (S404). When receiving the capture request, the operating system 21 performs screen capture (S405), and stores the image data of the image displayed on the display 106 in the clipboard 23 (S406). The enlarged capture software 32 stores the image data stored in the clipboard 23 in the memory 102 in association with identification information (for example, A to D in the example of FIG. 6) assigned to the divided images (S407).

  When the above processing is performed for each of the four divided images, four pieces of image data obtained by enlarging the divided images are stored in the memory 102. The enlarged capture software 32 combines the four image data stored in the memory 102 to generate enlarged image data (S408), and stores the generated enlarged image data in the clipboard 23 (S409) (enlarged image data). Storage).

  In this way, image data obtained by enlarging the entire image of the distribution diagram can be stored in the clipboard 23. Thereby, the whole image of a distribution diagram can be stored in the clipboard 23 as image data with higher resolution using a general and easy method called screen capture. Therefore, the form printing software 33 can paste and print image data having a higher resolution stored in the clipboard 23, so that the distribution diagram can be sent to a printer having a resolution much higher than the resolution of the display 106. In the case of outputting the entire image, it is possible to print more details than when the entire image is simply screen-captured.

  8 and 9 show examples of forms printed by the form printing software 33. FIG. FIG. 8 is an example of a form in which the entire image of the distribution diagram displayed on the display 106 is simply pasted and printed with image data captured by the screen capture function provided by the operating system 21. On the other hand, FIG. 9 shows an example of a form in which the image data stored on the clipboard 23 is pasted and printed by the above-described enlargement capture software 32. In this way, compared to the case where the image data captured by the screen capture unit 22 is printed as it is, by printing the enlarged image data captured by the enlarged capture software 32 as described above, a more detailed image can be printed. can do. Furthermore, although the size of the image data captured by the screen capture function that is normally provided in the operating system 21 depends on the size of the display 106, according to the enlarged capture software 32 of the present embodiment, Regardless of the size of the display 106, image data of an arbitrary size can be captured.

  Further, the enlarged capture software 32 does not access the data file used by the power distribution diagram display software 31, and uses the screen capture function that is normally provided in various operating systems 21, thereby displaying the display. The image displayed on 106 can be captured by screen capture. Therefore, the enlarged capture software 32 can be easily created. Further, the distribution diagram display software 31 is made to take in higher-definition image data by using existing software without making a change that incorporates a new function such as output of an image file, for example. be able to.

  Further, since the enlarged image data captured by the enlargement software 32 is stored in the clipboard 23, the user may paste it from the clipboard 23 to the form printing software 33. For example, in order to perform an operation for enlarging a distribution diagram using image editing software or the like, in addition to the operation of the form printing software 33, the user must be familiar with the operation of the image editing software. In the form of the computer 10, the user can print higher-definition image data without taking any trouble other than the operation of the existing form printing software 33.

  In the present embodiment, the form print software 33 transmits a capture request to the enlarged capture software 32. However, the present invention is not limited to this. For example, the form print software 33 transmits a capture request to the operating system 21. The enlarged capture software 32 may receive a notification that the operating system 21 has received the capture request. Further, the enlarged capture software 32 does not receive a capture request from the form printing software 33, for example, at the timing when it is detected that the user of the computer 10 presses the “Print Screen” key, as shown in FIG. Image data capture processing may be performed.

  In addition to the transmission of the control command, for example, the input data from the input device 105 such as a keyboard and a mouse is created for the control of the distribution diagram display software 31 by the enlarged capture software 32, and the generated input data is distributed. You may make it perform by transmitting to the figure display software 31. FIG. In this case, even when the distribution diagram display software 31 does not have a function of receiving a control command, it is possible to cope without changing the distribution diagram display software 31.

  In the present embodiment, the total number of distribution diagram images is divided into four. However, the number is not limited to this, and can be divided into two or more arbitrary numbers. However, if the number of divisions is too large, the amount of image data increases in proportion to the number of divisions, and the processing time increases, so about four divisions are preferable. By making it into about 4 divisions, it is possible to improve the software response without constraining storage resources.

  Although the present embodiment has been described above, the above examples are for facilitating the understanding of the present invention, and are not intended to limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and the present invention includes equivalents thereof.
