  • the image processing apparatus of the present invention is an image processing apparatus for filling a graphic object with a gradation pattern, wherein gradation pattern generating means for generating a basic gradation pattern in any one of a horizontal direction and a vertical direction; Drawing position determining means for determining a drawing start position based on the direction of the pattern and a “shift amount” obtained from a distance in a direction orthogonal to the gradation pattern direction; and drawing in the gradation pattern direction from the drawing start position. It includes gradation pattern drawing means.
  • An image processing program according to the present invention is for causing a computer to execute the image processing method according to the present invention.
  • the above-described image processing method can be realized by a large-scale computer, a personal computer, or an embedded device such as a portable terminal.
  • the recording medium of the present invention is a computer-readable recording medium on which the image processing program is recorded.
  • the image processing method of the present invention can be easily executed by various information devices such as a personal computer, a mobile device, a portable terminal, a PDIA, and a large-scale computer. Therefore, when drawing a gradation pattern for a graphic object on various information devices, there is no need to calculate the gradation color for each pixel, and the computer can perform high-speed processing. By using, it is possible to realize high-speed gradation processing with light processing. Also, gradation can be formed in any direction in each information device. In addition, high-performance and deeply expressive gradation drawing such as pad / repetition ⁇ reflection function and multi-color gradation function can be realized while suppressing reduction in processing speed.

Abstract

Pour afficher un objet graphique, on regroupe les pixels en une matrice comprenant une direction horizontale et une direction verticale. Un stade de génération de motifs de gradation permet de générer un motif de gradation de base dans une direction parallèle à la direction horizontale. Lorsque le motif de gradation de base est copié avec succès dans la direction verticale, un stade de copie permet de copier le motif de gradation de base à partir d'une position (k) décalée dans la direction horizontale.
