Embodiment 1

[0055] As shown in Figure 1, the process of image decoding and display in this embodiment includes the following steps:

[0056] Step S101, calculating the line drawing decoding coefficient of the image according to the screen resolution, the layout display ratio and the image resolution;

[0057] When the system needs to draw the layout and draw to the image block of the layout object, first calculate the drawing line decoding coefficient of the image according to the following formula:

[0058] X=Y / (Z×A) (1)

[0059] Among them, X represents the line drawing decoding coefficient, Y represents the image resolution, Z represents the screen resolution, and A represents the layout display ratio.

[0060] Step S102, judging whether the drawing line decoding coefficient is greater than 1, if yes, proceed to step S104, otherwise proceed to step S103;

[0061] Since the resolution of the image is generally higher than the resolution of the screen, that is, the decoding coefficient...

Embodiment 2

[0097]When displaying the same image file, once the layout display ratio changes, the line-drawing decoding coefficient will also change, and once the line-drawing decoding coefficient changes, the image file must be recalculated based on the newly calculated line-drawing decoding coefficient of the image Do line drawing decoding again, which will also bring a large load to the image decoding and display system. Therefore, in this embodiment, the line drawing decoding coefficients are divided into levels in advance. When the line drawing decoding coefficients calculated by the image belong to a specific When the level is selected, the minimum value among the line-pumping decoding coefficients corresponding to the level is used as the line-pumping decoding coefficient of the image. Therefore, when the line-drawing decoding coefficient of the image changes, but the line-drawing decoding coefficient before and after the change belongs to the same level, there is no need to decode ...

Abstract

This image decoding display method includes: Draw-line decodes the image according to the image draw-line decoding coefficient (IDDC). Print the decoded image onto the image block of the plate object. This image decoding display system (IDDS) consists of the printing module (PM) and the draw-line decoding module (DDM). According to IDDC, DDM draw-line decodes the image and outputs it to PM. PM prints the decoded image onto the image block of the plate object. This technical scheme reduces the load on IDDS and raises the efficiency of IDDS.

Description

technical field [0001] The invention relates to the field of image information processing, in particular to an image decoding and display method and system. Background technique [0002] In order to ensure that the image files under different image format encoding methods can be displayed correctly on the layout, it is necessary to decode the image files, convert the image files under different image format encoding methods into device-related display bitmap data, and then decode The final image data is displayed on the screen. [0003] At present, the usual image decoding process is completely based on the original information of the image, that is, the data information after decoding is in one-to-one correspondence with the data information before decoding. However, due to the large amount of image data in high-resolution and large-size image files, if you completely rely on the original information to decode, the amount of data that needs to be decoded is huge, and the f...
