Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a document creation device that may include images.
In particular, the present invention relates to an image aggregation device for enlarging or reducing the image.

[Prior art]

In a document creation device t that may include an image, that is, a document creation device, or a device including a word processor, it is desirable that the four drawings associated with the text be on the same page as the corresponding text.

Here, the size and aspect ratio of the empty space of the page into which the image is to be inserted often does not match the R-width ratio of the image to be inserted. In such a case, it would be better if you could change the M and horizontal ratio of the drawing saw to be inserted.

However, with conventional text creation devices of this type, although it is possible to enlarge or reduce the image to be inserted, the vertical and horizontal enlargement and reduction ratios are the same, so the free space on the page where the image should be inserted is cannot be inserted properly. In other words, as shown in FIG. 1(a), there is a rectangular area P on the display screen CRT into which an image should be inserted, and the image to be inserted is A.
Suppose that Since this image A is too small compared to the area P, why not use the cursor movement key Ke on the keyboard KB in FIG. 1(b) as a function key? and alphanumeric key KAM
After setting the cursors C1 and C on image A by operating , the enlargement magnification etc. are input to obtain an enlarged image A'. In this case, image A will be enlarged 1.5 times both vertically and horizontally, and will soon be the size of area P. However, while the area P is long, the enlarged image A' is not vertically long, and the area P
There is a large amount of empty space left at the top and bottom of the screen, which is a problem.

〔the purpose〕

The invention has been made in consideration of the above-mentioned points, and provides a document creation device that can arbitrarily convert the aspect ratio of an image to be inserted and fit the image into the empty space of the page to be inserted. [Structure] An embodiment of the present invention will be described below with reference to FIGS. 2 to 41.

Figures 2 (a) and (b) show how the image magnification changes according to the invention when it is enlarged.
As shown in 1), only the horizontal direction is enlarged, and then, as shown in FIG. 1(b), only the vertical direction is enlarged. That is, set cursor C8 at the lower left end of image A in area P, and cursor C7 at the upper right end, and then indicate the horizontal enlargement boundary with cursor Ct'.-0 This causes image A to be enlarged only in the horizontal direction. tiii+i i'fi A'
becomes. Next, use the cursor CI/ to indicate the vertical expansion boundary and expand j'! in the vertical direction as well as the horizontal direction! 'j angle I A '' is obtained.

Here, the horizontal magnification ratio and the vertical magnification ratio are set separately, and the enlarged image A can be made vertically long regardless of whether the original image is 〇 or 1. As a result, 1 An image of a candlestick is inserted into the empty space of the page where one's own work should be suppressed.

FIG. 3 is a block diagram showing the 4'I configuration of the production system according to the present invention. Where to go for this device: Near 1 device cpu

Image memory MEM, enlargement, i? +j small circuit P; /'
JLβ and a keyboard/display interface I/)' are interconnected by an address bus BA-, a data bus Bn, and a control bus Ba, and a keyboard I<B and a display CRT are connected to the interface I/F.

FIG. 4 is a flowchart showing the operation of the apparatus shown in FIG. 3, which consists of 32 steps S to Sat performed under the control of the arithmetic processing unit CPU. That is, first, a message indicating the upper right corner of the processing area, that is, the image to be inserted, is output to the display CRT (Sl). Based on this, when the operator operates the cursor movement key Kc of the keyboard KB, the upper right end instruction is completed (Ss). Similarly, the lower left end of the area to be processed is designated (Sl=84).

Next, based on the message (SS) indicating the upper left end of the destination area, an instruction is given (all), and when there is an instruction to start moving at M (Sy), it is determined whether the area is correctly specified (Sy). , ), if the instruction is not correct, the process returns to step Sl, and if the instruction is correct, the image data is transferred to the address of the destination area of the image memory MEM (St.pStt).

When the transfer is completed, all the image data is output to the display CRT (Sl), and a message for horizontal scaling and a message for indicating the upper right edge of the boundary of the scaling number are output (81m + 814). If there is an instruction to start magnification (818), after determining whether the area is correctly specified (Ssa), calculate the magnification ratio (5ss),
The magnification ratio is instructed to the enlargement/reduction circuit E/R (Stt).

As a result, the image data of the area to be processed is transferred to the enlargement/reduction circuit E/R, which performs processing for enlargement or reduction, and sends the results back to the image memory MEM (S!).
. When the horizontal processing is thus completed (Stt), all image data is displayed on the display CRT (SJ).

Processing similar to the scaling processing in the horizontal direction is also performed in the vertical direction (Ssa to Ss').

Here, enlargement and reduction are performed by interpolation method 2 thinning method.

〔effect〕

As described above, the present invention is configured so that the aspect ratio of the image to be inserted is arbitrarily converted and the image is inserted at an arbitrary position, so that the image is inserted to fit the empty space of the page where the image is to be inserted. be able to. Therefore, it is possible to easily and quickly insert an image effectively into a suitable position on a document page, or to form an easy-to-read drawing by combining it with other drawings.
