摘 要: 传统平面设计系统不能为用户提供设计几何理论方面的依据,导致设计作品不和谐,为此,提出基于计算机辅助的平面设计系统。将图像添加至所设计系统,把图像放在系统图层的最底层,将其锁定,保证计算机辅助过程中采用的辅助线和模板叠加在图像上层无法被遮挡。确定图像导入方向,获取轮廓比例,将其与不同动态矩形比例相比,给出该图像和标准值的差值和建议调整值。依据黄金分割理论,通过人机交互绘制分割线求出分割线和整幅图片、分割线与分割线间的比例关系,利用标准辅助线模板完成对图像的分析。实验结果表明,该设计系统设计的作品符合几何学,在视觉上很和谐,评价结果好。

Abstract: The traditional graphic design system can′t provide the basis of the geometry design theory for user, so the design work is disharmonious. Therefore, a new graphic design system based on computer?aided design is proposed. The image is added into the design system, put on the bottom of the system layer, and locked to make sure that the auxiliary lines and templates superimposed on the upper layer of the image can′t be sheltered in the computer?aided process. The import direction of the image is determined to obtain the contour ratio, and compare it with different dynamic rectangle ratios. The difference between the image and standard value and the suggested adjustment value are given. According to the golden section theory, the segmentation line is drawn by means of human?computer interaction to work out the proportion relation between the segmentation line and whole image, as well as the segmentation lines. The standard auxiliary line template is used to analyze the image. The experimental results show that the design work of the system is consistent with geometry thought, and harmonious in vision, and its evaluation results are perfect.

平面设计作品需具有语言简洁、艺术性强、可有效反映作者艺术风格的特点,尽管在多媒体迅猛发展,3D技術被广泛应用的今天,平面设计图像也有很高的应用价值[1?2]。秩序美是平面设计的关键,优秀的平面设计会遵循可体现设计几何的准则,使得平面设计作品在视觉上更加和谐[3]。所以,衡量设计作品的一个重要因素为分析设计作品中不同元素间的位置关系和比例关系。
当前平面设计系统虽然能够为用户提供设计作品的平台,但不能为用户提供设计几何理论方面的依据,用户在进行设计时,仅依据自身艺术素养完善作品,无几何学知识辅助,设计作品杂乱不和谐[4]。……
