摘要 背景在日常生活中很常见,尤其是无缝背景,如墙面的墙纸、地面上铺的地板革、身上穿的花纹布料衣服、网页背景等。这些图案的背景是如何设计出的呢?事实上,设计人员并没有为现实生活中丰富多彩的生产材料都对应地设计出背景,而是为了节约时间、空间和材料等限制,把整幅图像看作是由若干个小图像拼接而成,并认为这些小图都是由矩形图定义而成的即背景。如果各个矩形小图像之间没有接缝的痕迹,小图像之间也完全吻合,即是无缝背景。各个矩形小图像是通过定义图案来实现的;要想定义图案中的图像在拼接过程中没有接缝的痕迹,必须做到定义图案中的图最左边和最右边,最上边和最下边的像素相互融合,没有接缝的痕迹,因此介绍了好几种方法来实现无缝背景效果。如位移方法将小图最左边和最右边的像素,最上边和最下边的像素拼在一起,用图章、模糊工具实现像素的融合;在Image Ready中用拼贴生成器等方法来实现效果。 Background is very common in the ordinary life,especially for the seamless background such as wallpaper on the wall,floor leather on the ground,flower pattern clothes worn on body and web background. How to design out these pattern backgrounds? In fact,it is impossible for the design personnel to work out the corresponding background for all the rich and colorful production materials in real life. In contrast,in order to save time,space and material limitation,the design personnel generally regards the whole picture as splicing formation of many small images,and these small images is defined as rectangle drawing,namely background. If each small rectangle drawing has no seaming trace,and these images match well each other,namely seamless background. Each small rectangle image is achieved through defining pattern. If the images of the defined patterns have no seaming trace during splicing,it is necessary to make the leftmost,rightmost,upmost and undermost pixels in the images of defined patterns mutual fusion,and the seaming traces are not present. In this paper,several methods to realize seamless background have been introduced,for example,using the displacement approach,the leftmost,rightmost,upmost and undermost pixels in the small images are cohered together,and then the pixels are actualized mutual fusion by the illegibility tool,and the final effect is achieved by spell paste maker in Image Ready.
