Plan display device that displays enlarged/reduced image of original image with indication and plan display program for displaying same
First Claim
1. A drawing display device, comprising:
- original image storage means for storing an original image having first and second sides that are perpendicular to each other, the first and second sides defining x and y axis directions of the original image, respectively;
region designation means for designating a desired region that is associated with a specified region of the original image;
desired image saving means for reading a desired image having an area corresponding to the entire area of the designated desired region from the original image and storing the desired image separately from the original image, the desired image being arranged at a position corresponding to a position of the specified region inside the original image along one of the x and y axis directions of the original image and having first and second sides that are perpendicular to each other;
enlargement/reduction ratio acquisition means for acquiring an enlargement/reduction ratio (P) with respect to the original image as the original image is enlarged/reduced;
enlarged/reduced original image creating means for forming an enlarged/reduced original image by changing magnification of the original image by the acquired enlargement/reduction ratio (P) in both the x axis direction of the original image corresponding to the first side of the original image and the y axis direction of the original image corresponding to the second side of the original image;
enlarged/reduced desired image creating means for forming an enlarged/reduced desired image by changing magnification of the desired image by the acquired enlargement/reduction ratio (P) at least in a first direction of the desired image corresponding to the first side of the desired image, in correspondence with the enlargement/reduction of the original image; and
display means for displaying the created enlarged/reduced original image and for displaying the enlarged/reduced desired image along an inner periphery of the display means at the position corresponding to the position of the specified region inside the original image along one of the x and y axis directions of the original image, whereinthe position of the enlarged/reduced desired image relative to the position of the specified region remains the same even after the enlargement/reduction of the original image and the desired image.

Abstract
When enlarged/reduced images to be displayed based on a predetermined original image are displayed on a display screen, each of the enlarged/reduced images is created and displayed at a higher speed. Therefore, desired regions within an original image are designated, and desired images including the entire designated desired region are read from the original image, and stored separately from the original image. Then, an enlargement/reduction ratio with respect to the original image is acquired, and an enlarged/reduced original image obtained by enlarging/reducing the original image with the enlargement/reduction ratio in both a long-side direction and a short-side direction is created and displayed on a display screen. Further, enlarged/reduced desired images obtained by enlarging/reducing the desired images that are separately stored only in the long-side direction with the enlargement/reduction ratio are created and displayed in the vertical/horizontal target regions so as to be superimposed on the enlarged/reduced original image.

11. A non-transitory computer readable storage medium containing a drawing display program for causing a computer to implement:
-
a region designation function of designating a desired region that is associated with a specified region of an original image stored in an original image storage device, the original image having first and second sides that are perpendicular to each other and that define x and y axis directions of the original image, respectively; a desired image saving function of reading a desired image having an area corresponding to the entire area of the designated desired region from the original image and storing the desired image separately from the original image, the desired image being arranged at a position corresponding to a position of the specified region inside the original image along one of the x and y axis directions of the original image and having first and second sides that are perpendicular to each other; an enlargement/reduction ratio acquisition function of acquiring an enlargement/reduction ratio (P) with respect to the original image as the original image is enlarged/reduced; an enlarged/reduced original image creating function of forming an enlarged/reduced original image by changing magnification of the original image by the acquired enlargement/reduction ratio (P) in both the x axis direction of the original image corresponding to the first side of the original image and the y axis direction of the original image corresponding to the second side of the original image; an enlarged/reduced desired image creating function of forming an enlarged/reduced desired image by changing magnification of the desired image by the acquired enlargement/reduction ratio (P) at least in the first direction of the desired image corresponding to the first side of the desired image, in correspondence with the enlargement/reduction of the original image; and a display function of displaying the created enlarged/reduced original image and for displaying the enlarged/reduced desired image along an inner periphery of the display means at the position corresponding to the position of the specified region inside the original image along one of the x and y axis directions of the original image, wherein the position of the enlarged/reduced desired image relative to the position of the specified region remains the same even after the enlargement/reduction of the original image and the desired image.
