摘要： A printer produces an improved pixel image representation of encoded image data when sub-image portions are combined into larger image portions. The printer receives encoded image data as a data stream of sub-image segments and stores the sub-image segments. Each sub-image segment includes associated graphics state information which defines at least some image attributes of the sub-image segment. When each new sub-image segment is completely received, it is placed on a closed image list. Upon such listing, the printer's processor compares the graphics state information and boundary data for the now complete sub-image segment with at least one other listed sub-image segment in the closed list. The processor combines the new sub-image segment with the other sub-image segment if both a matching graphics state and matching boundary data are found. An image processor within the printer then subjects the combined sub-image segments to spatial processing as a unitary image.

摘要翻译： 当子图像部分被组合成更大的图像部分时，打印机产生编码图像数据的改进的像素图像表示。 打印机接收编码图像数据作为子图像段的数据流并存储子图像段。 每个子图像段包括定义子图像段的至少一些图像属性的相关联的图形状态信息。 当每个新的子图像段被完全接收时，它被放置在封闭的图像列表上。 在这样列出的情况下，打印机的处理器将现在完成的子图像段的图形状态信息和边界数据与关闭列表中的至少一个其他列出的子图像段进行比较。 如果找到匹配的图形状态和匹配边界数据，处理器将新的子图像段与另一个子图像段组合。 然后，打印机内的图像处理器将组合的子图像段作为整体图像进行空间处理。
