    • In an image editing apparatus adapted to cut a plurality of regions of any size from a plurality of documents and prepare a new document by sticking the cut regions on a sheet. The cut regions are designated by a light pen of an instruction input section for each document displayed on a CRT display. The coordinate information of the cut regions is stored in a RAM in a sticking region computer and the image information is stored in a first buffer (RAM). A ROM in the sticking region computer stores information relating to a plurality of basic patterns representing the manner of sticking a plurality of cut regions. The coordinates of a plurality of sticking regions are calculated for each basic pattern on the basis of the coordinate data of the cut regions. An image processor causes the image data of the cut regions which are stored in the first buffer to be transferred to memory area of a second buffer (RAM) which is designated by the coordinates of the corresponding sticking regions. The editing of images is carried out for each basic pattern. The "edited" image data stored in the second buffer is displayed on a second CRT display.
    • 在一种图像编辑装置中,适于从多个文档中切割出多个尺寸的区域,并通过将切割区域粘贴在片材上来准备新的文档。 切割区域由CRT显示器上显示的每个文档的指示输入部分的光笔指定。 切割区域的坐标信息存储在粘贴区域计算机的RAM中,图像信息存储在第一缓冲器(RAM)中。 粘贴区域计算机中的ROM存储有关表示多个切割区域的粘贴方式的多个基本图案的信息。 基于切割区域的坐标数据,针对每个基本图案计算多个粘贴区域的坐标。 图像处理器将存储在第一缓冲器中的切割区域的图像数据传送到由对应的粘贴区域的坐标指定的第二缓冲器(RAM)的存储区域。 对每个基本图案进行图像的编辑。 存储在第二缓冲器中的“编辑”图像数据被显示在第二CRT显示器上。
