Abstract

PURPOSE:To realize the optional selection for magnification/reduction between the pictures similar to an original rectangle and the pictures not similar to said rectangle and to improve operability of a document processor, by setting a magnifying/reducing function with variation in accordance with the direction of an auxiliary line for magnification/reduction. CONSTITUTION:The markers are displayed at the middle points of four sides and four apexes of a rectangle to designate the magnifying/reducing direction to the pictures within the rectangle set for magnification/reduction. Then a user designates one of those displayed markers via a pointing input device. Thus the auxiliary lines are displayed in the upper direction, the lower direction, the left direction, the right direction, the upper left direction, the lower left direction, the upper right direction and the lower right direction respectively based on and through the designated marker. If the magnifying/reducing direction is shown by the auxiliary lines set in the upper left direction, the lower left direction, the upper right direction and the lower right direction, for example, the magnifying/reducing directions are designated on those auxiliary lines via the pointing input device. Thus a size can be designated after magnification/reduction without changing the ratio between the vertical and horizontal sides. Thus it is possible to optionally select the magnification/reduction between the pictures similar to an original rectangle and the pictures not similar to said rectangle when the pictures are interactively magnified and reduced within a rectangle.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an image processing method, and more particularly, to an image processing method.

The present invention relates to an image enlargement/reduction specifying method for interactively specifying enlargement/reduction of an image within a rectangle during image editing processing.

[Conventional technology]

When scaling an image interactively in a document processing device that performs editing processing while displaying text or figures on the screen, conventionally, the image within a rectangle is specified by specifying a point after scaling. Change the magnification.

Alternatively, the rectangle after scaling is obtained by moving the mouse, which is a pointing input device, up and down and left and right.

The prior art related to the image enlargement/reduction designation method is described in, for example, Japanese Patent Application Laid-Open No. 60-249186.

[Problem that the invention seeks to solve]

However, conventionally, when an image within a rectangle is interactively enlarged or reduced, it is possible to only enlarge or reduce an image that is similar to the original rectangle, and it is possible to enlarge or reduce an image that is similar to the original rectangle or an image that is not similar to the original rectangle. It is not recognized that scaling can be arbitrarily selected to further improve the usability of the document processing device.

In particular, the mouse can move freely on a plane, so if the rectangle after scaling is obtained by moving the mouse up/down/left/right, the mouse may move in directions other than the direction the user intends to scale. In such a case, the user will not be able to specify the scaling in the direction he or she intends.
There was a problem in that the ratio of each side was set differently from that of the original rectangle, and the vertical and horizontal magnification of the rectangle was different. That is,
When specifying the scaling of an image within a rectangle by moving the cursor on the display screen as the mouse moves, if you want to scale to a rectangle similar to the original rectangle, move the mouse (left/right movement amount: vertical movement amount) It must be moved to = (the length of the horizontal side of the original rectangle, the length of the vertical side of the binary rectangle).

At that time, even if you intend to move the mouse in the intended direction to specify the size of the rectangle, if the mouse is not moved exactly in the direction the user intended, then The ratio of each side of the rectangle will change.

The present invention has been made in consideration of the above points, and includes:
The purpose of this is to further improve the usability of document processing devices by arbitrarily selecting the scaling of images similar to and dissimilar to the original rectangle when scaling an image within a rectangle interactively. , and when scaling an image similar to the original rectangle, the rectangle after scaling.

It can be displayed as intended by the user. This is an attempt to provide a new method for specifying image enlargement/reduction that has never existed before.

[Means for solving problems]

To achieve the above object, the present invention is directed to an image editing method in which arbitrary coordinates are specified by moving a cursor on an image displayed on a display device using a pointing input device such as a mouse or a light pen. do.

Therefore, if the target image of the H collection is within a rectangle specified by two diagonal points, and you specify the enlargement/reduction of the image within the rectangle interactively, , by displaying a direction indicating point (marker) indicating the direction of scaling of the image within the rectangle, and specifying one marker in the direction in which you intend to scale the image using the pointing input device, you can move through the specified marker as described above. , Moreover, an auxiliary line in the scaling direction is displayed using a marker existing on the opposite side or the opposite vertex of this marker as a reference point in the scaling direction, and a point indicating the size of the rectangle after scaling is specified using the pointing human device. Then, the size of the rectangle after scaling is displayed with a rectangular frame that passes through the marker.

If the display auxiliary line is an auxiliary line passing through the midpoint of the side of the rectangle, the frame indicating the scaled size is moved only in the direction of the auxiliary line of the point indicating the scaled size. On the other hand, if the display auxiliary line is an auxiliary line that passes through the apex of the rectangle, and the point indicating the size after scaling is on the auxiliary line, the ratio of the vertical and horizontal sides of the rectangle is A frame indicating the size after scaling that will not be changed is displayed, and on the other hand, the display auxiliary line is an auxiliary line that passes through the apex of the rectangle, and the point indicating the size after scaling is not on the auxiliary line. In some cases, a frame indicating the size after scaling is displayed by changing the ratio of the vertical and horizontal sides of the rectangle at the position of the specified point, and the size of the rectangle after scaling is specified.

[Effect]

The present invention is as described above, and in the present invention, markers specifying the scaling direction are placed at the midpoints of the four sides and the four vertices of the rectangle for an image within a rectangle that is set for the purpose of scaling. The user can select from among the displayed markers.
When you specify one with the pointing input device, the auxiliary line passes through the specified marker and moves upward, downward, leftward, rightward, upper leftward, lower leftward, upperrightward, and lowerrightward depending on the position of the specified marker. is displayed.

To explain this in more detail, if the specified marker is at the upper left edge, the auxiliary line will be displayed from the lower right edge of the rectangle through the upper left edge to the upper left direction, and if the specified marker is at the midpoint of the left side,
The auxiliary line will be displayed in the left direction from the midpoint of the right side of the rectangle, passing through the midpoint of the left side of the rectangle, and if the specified marker is at the lower left edge, the auxiliary line will be displayed in the lower left direction from the upper right edge of the rectangle, passing through the lower left edge of the rectangle. and the specified marker is the midpoint of the bottom side, the auxiliary line will be displayed downward from the midpoint of the top side of the rectangle through the midpoint of the bottom side,
If the specified marker is at the lower right edge, the auxiliary line will be displayed from the upper left edge of the rectangle through the lower right edge to the lower right direction, and if the specified marker is at the midpoint of the right side.

The auxiliary line will be displayed in the right direction from the middle point of the left side of the rectangle, passing through the middle point of the right side, and if the specified marker is the upper right edge, the auxiliary line will be displayed in the upper right direction from the lower left edge of the rectangle, passing through the upper right edge. If the specified marker is the midpoint of the top side, the auxiliary line is displayed upward from the midpoint of the bottom side of the rectangle through the midpoint of the top side.

If the scaling direction is an auxiliary line that indicates the upper left, lower left, upper right, or lower right directions, if you specify the scaling light on the auxiliary line with a pointing input device, the ratio of the vertical and horizontal sides will not change. You can specify the size after scaling.

Also, the scaling direction is upper left, lower left, upper right,
It is an auxiliary line indicating the lower right direction, and if you specify a scaling light with a pointing input device other than on the auxiliary line,
You can specify the size after scaling by changing the ratio of the vertical and horizontal sides of the rectangle at the specified point.

Furthermore, if the enlargement/reduction direction passes through the midpoint of each side, the enlarged/reduced size can be specified only in the direction of the auxiliary line indicating the enlarged/reduced size.
