Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image processing device that displays a predetermined image within a window area.

(Prior Art) In conventional image processing devices, when displaying tree@structure information in a window, it is not possible to perform reduction processing on the entire image of the tree to be displayed, and the size of the entire image is fixed. Therefore, when the entire tree image becomes larger than the window area, only a portion of the entire tree image corresponding to the window area is displayed.

[Problem to be Solved by the Invention] By the way, in the conventional image processing device described above, when the entire image of the tree is larger than the window area, only a portion of the image of the entire tree is displayed within the window area. , to display an image of a tree that is not visible within the window area, you must scroll to see the entire tree.

Therefore, if the entire image of the tree becomes larger than the window area while creating the tree structure, it is necessary to scroll the entire image of the created tree and then create the tree structure again.

Additionally, if the overall tree image is larger than the window area, the user must scroll the entire tree image, so the user cannot accurately see the relationship between each node in the tree structure. , and it has the disadvantage that it cannot be recognized quickly.

The present invention solves the above-mentioned drawbacks and provides an image processing device that can accurately and quickly recognize the entire image by always displaying the entire image within the window area. purpose.

[Means to solve the problem]

In the present invention, a calculation means for calculating the ratio between the size of the window area and the size of the entire image to be displayed;
and processing means for enlarging or reducing the entire image based on a magnification corresponding to the ratio.

[Operation] In the present invention, the size of the window area and the size of the overall image of the tree structure to be displayed are compared, and as a result of the comparison, if the overall image of the tree structure is larger than the window area,
The overall image is reduced at a magnification according to the tL ratio of the two sizes and displayed in the window area, and conversely, when the overall image of the tree structure is smaller than the window area, the overall image is displayed in the window area. The image is enlarged at a magnification according to the size ratio and displayed in the window area, and the entire tree structure is always displayed within the window area.

〔Example〕

Embodiments of an image processing apparatus according to the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a block diagram showing an embodiment of an image processing apparatus according to the present invention. In the figure, the instruction unit 1 includes, for example,
Consists of mouse and keyboard, display 2
This is an instruction to set a window area above the window area and to display a desired image, such as a tree structure image, in the set window area.

The window area information buffer 3 stores window area information indicating the window area set by the user, and the image information buffer 4 stores window area information indicating the window area set by the user.
, and stores image information indicating a desired image read from a file device (not shown).

The enlargement/reduction processing unit 5 compares the previous window area and the currently set window area, and also compares the tree structure displayed in the previous window area and the tree structure that is currently not desired to be displayed. Furthermore, if there is a change in either the window area or the tree structure as a result of these comparisons, the entire tree structure is enlarged or reduced.

That is, the enlargement/reduction processing unit 5, for example, as shown in FIG.
If the size is b, and the overall tree structure is the size of the vertical length - A and the horizontal length - B as shown in Figure 3, then a/A b/B... The entire image of the tree structure is enlarged or reduced based on each calculated value of the calculation shown in equation (1).

The control unit 6 controls each of the above units, and for example, controls the transfer of an image read from a file device (not shown) to the image information buffer 4, and transfers information from the window area information buffer 3 and the image information buffer 4, respectively. is read out, and performs various controls such as transfer control of this information to the enlargement/reduction processing section 5 and display control of displaying the image on the display 2.

Next, the tree structure display operation of the image processing apparatus will be explained based on the flowchart of FIG.

When the user operates the instruction unit 1 to set a window area and further instructs a desired image to be displayed within the window area, for example, an image of a tree structure, the control unit 6 controls the window area information buffer. 3 (step 10), and the designated tree-structured image information from the image information buffer 4 (step 11).

The control unit 6 then sends the read window area information and image information to the enlargement/reduction processing unit 5.

When the window area information and image information sent from the control unit 6 are input, the enlargement/reduction processing unit 5 adjusts the size of these window areas based on the previous window area information and the window area information in step 10. In addition to comparing the sizes, the overall images of these tree structures are compared based on the image information of the previous tree structure and the image information of the tree structure in step 11, and the result of these comparisons is In step 12), it is determined whether there is any change in the overall image of the tree structure. If there is no change, neither enlargement nor reduction processing is performed on the overall image of the tree structure.

In this case, the entire tree structure will be displayed in its original size (step 13).

On the other hand, if there is a change in either the window area or the overall image of the tree structure in step 12, the enlargement/reduction processing unit 5 changes the size based on the size of the window area and the overall image of the tree structure. The above formula (1)
The entire image of the tree structure is enlarged or reduced according to the enlargement value (step 14).

The entire image of the tree structure thus enlarged or reduced is displayed in the window area (step 15).

Next, as shown in FIG. 5, when the user wants to change the tree structure 30 displayed in the window area 20 in real time, such as deleting nodes or adding nodes, the user can change the tree structure 30 displayed in the window area iii. ! In an area other than 20, a tree structure property for specifying the attribute content indicating a change in the tree structure is displayed, and the attribute content can be changed by specifying the attribute content.

Now, the user uses the tree structure property to create the tree structure 30 shown in FIG. 5, as shown in FIG.
For example, if you set the attribute content to newly add nodes D and E as child mates of node C and change the tree 1 structure, of course the tree structure 30A after the change
The overall image of the tree structure 30 becomes larger than the previous overall image of the tree structure 30.

However, after the entire image of the tree structure 30A as shown in FIG. 6 is reduced in real time by the enlargement/reduction processing unit 5, the entire tree structure is reduced to the window area as shown in FIG. 20 is displayed.

Furthermore, as shown in FIG. 8, the entire tree structure 30B composed of a plurality of nodes is
0, the user can view the tree structure 30B
In some cases, it may not be possible to accurately grasp the relationship between each node.

In such a case, the user sets the window area 20B in an area different from the window area 2OA, and then specifies the desired image 30C that is included in the overall tree structure that the user wants to display in the window area 20B. For example, by setting the area surrounded by the dotted line shown in FIG. 8, based on the size of the image 30G and the size of the window area 20B within the set area, as shown in FIG.
The image 30C within the set area is enlarged and displayed in the window area 20B. This allows the user to easily understand the relationship between each node of a portion of the tree structure within the set area.

In addition, in the above embodiment, the enlargement/
Although we have explained the reduction process, for example, even if the entire tree structure of the item selected by the user from among multiple tree structure items displayed in a menu format is larger than the set window area, After the entire image of the tree structure is reduced, it is displayed in the window area.

In addition, in the above embodiment, when changing the structure of one tree,
Although this is done using the tree structure property, the present invention is not limited to this, and the tree structure may be changed by calling a function that indicates a change in the tree structure.

As described above, according to this embodiment, the entire image of the tree structure can always be displayed in the window area, so there is no need to scroll the entire image of the tree structure as in the conventional case. In particular, since the entire image of the tree structure is enlarged or reduced in real time and an appropriate tree structure is displayed on the screen, the tree structure can be created quickly.

〔Effect of the invention〕

Explain above! , - According to the present invention, the entire image of the tree structure is always displayed in the window area based on the size of the window area and the size of the overall image of the tree structure. The tree structure can be improved and the overall tree structure can be easily recognized.
