Abstract
Vector data indicating a plurality of points for representing an image is classified for storage under three groups: a group 1 of the vector data DP1, DP5, DP9 indicating indispensable points P1, P5, P9 required for recognition of graphics G; a group 2 of the vector data DP3, DP7 indicating first supplementary points P3, P7 for supplementing the points P1, P5, P9; and a group 3 of the vector data DP2, DP4, DP6, DP8 indicating second supplementary points P2, P4, P6, P8 for further supplementing the indispensable points P1, P5, P9 and first supplementary points P3, P7. When displaying an image, a selection is made between displaying the image represented by the group 1 and displaying the image represented by the group 1 plus the groups 2 and 3.
Claims11
A method of displaying a vector-mode image in which a plurality of points designated on a screen are linked to display the required image, comprising the steps of:
- classifying vector data, indicating a plurality of points for displaying the image, into a group of data indicating indispensable points required for recognizing the image, and a group of data indicating supplementary points for supplementing the indispensable points to display a more precise image, for storage on a storage member;
- and
- selecting between displaying the image represented only by the data group indicating the indispensable points and displaying the image represented by the data group indicating the indispensable points plus the data group indicating the supplementary points, when the image is displayed.
A system of displaying an image in which a plurality of points designated on a screen are linked to display the required vector image, comprising:
- a data storage member for classifying vector data, indicating a plurality of points for representing the image, into a data group indicating indispensable points required for a minimum recognition of the image, and a data group indicating supplementary points for supplementing the indispensable points to represent the more precise image, and for storing the vector data;
- and
- an image quality selection member for selecting between reading merely the data group indicating the indispensable points from said data storage member for displaying the image and reading the data group indicating the indispensable points plus the data group indicating the supplementary points from said data storage member for displaying the image.
