Embodiment Construction

[0014] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0015] figure 2 A flowchart showing a method for rasterizing a page digital image according to an embodiment of the present invention, including:

[0016] Step S10, analyzing the digital image of the page to obtain basic image information and image position information and image rasterization processing information. The basic image information includes: image data, image type, image width, image height, and image bit depth;

[0017] Step S20, decoding the data encoding type, obtaining the image data and storing it in the buffer;

[0018] Step S30, acquiring image data from the buffer, and performing rasterization processing on the image data by using the image type, image width, image height, image bit depth and image position information to obtain a rasterized page dot matrix.

[0019] The existing technology writes the data into the image intermediate...

Abstract

The invention provides a method for rasterization treatment of a page digital image, which comprises resolving the page digital image to obtain image rasterization treatment information of image positional information and image essential information comprising image data, image types, image width, image height and image bit depth; decoding data coding types to obtain the image data and saving the image data in a bumper; and obtaining the image data from the bumper and conducting the rasterization treatment on the image data by using the image types, the image width, the image height and the image bit depth to obtain a rasterization page dot matrix. The invention further provides a device for rasterization treatment of the page digital image. The method and the device reduce read-write operation of disc data files in a rasterization treatment process of the digital image, and substantially improve efficiency of the rasterization treatment of the digital image.

Description

technical field [0001] The invention relates to the field of digital typesetting, in particular to a rasterization processing method and device for page digital images. Background technique [0002] Page digital image rasterization processing refers to the digital image described by the page description language, according to its image description content, to interpret and generate the actual digital image page dot matrix data, for storage or printing of back-end output devices, phototypesetting, etc. use. Rasterization processing is a series of processes, including: analysis of original information such as width, height, bit depth, etc., image color processing, transfer curve processing, geometric transformation processing, etc. The entire processing process is to transform the image from the user coordinate space to the device coordinate space. After the entire processing is completed, the image will be placed in the device page dot matrix to complete the entire rasteriza...
