Description of drawings
Fig. 1 is a mass picture display packing process flow diagram in specific embodiment of the present invention.
Embodiment
Please referring to shown in Figure 1, the invention provides the method that a kind of mass picture shows, it comprises:
Step 101, the image of each angle under each fineness in the drafting scene.The scene here both can be that map space can be object, Virtual Space etc. also, determined the various level fineness for each scene, and the content of higher fineness performance is abundanter, meticulousr.
Step 102 is divided into sub-pictures with the image of each angle under described each fineness according to identical Pixel Dimensions and preserves, and preserves the thumbnail of all sub-pictures simultaneously.Can certainly be divided into the sub-pictures of different size, but be divided into the reasonable distribution that identical size helps storage space, also help management.In the prior art because disk file system generally adopts FAT or NTFS form, and they have the minimum memory unit, for ultra-large scene, as the picture of several ten thousand pixels, sub-pictures is cut apart meticulous more more can be near the desired content displayed of user.But simultaneously, certainly will cause the waste of storage space, therefore adopt the size after the image of same Pixel Dimensions can guarantee image segmentation, utilize as much as possible and save the space because the file amount is excessive.The thumbnail of sub-pictures also may be controlled to the size that satisfies the storage space optimum.In a specific embodiment, the thumbnail of described sub-pictures and sub-pictures is the integral multiple of the minimum memory unit of file system in the target storage medium.
Step 103 is with whole subimages under same sharpness, the angle or subimage thumbnail numbering.The method of numbering is a lot, in a specific embodiment, can adopt letter and digital combination number.Such as first group of employing letter, represent different fineness levels, second group is adopted the row of numeral sub-pictures in whole picture, and the 3rd group is adopted numeral, represents the row of sub-pictures in whole picture.Adjacent sub-pictures can adopt digital addition and subtraction 1 to obtain between the ranks, uses more convenient.
Step 104, the user is after selected scene fineness, angles of display and indication range, and all fall into the thumbnail of the sub-pictures in the described indication range under this fineness, the angle in the indication range that explicit user is chosen.
Step 105 shows that the sub-pictures in the described indication range is replaced described thumbnail.
The thumbnail that shows sub-pictures and sub-pictures in a specific embodiment, is determined the numbering of all subimages in the selected indication range and the position between the subimage earlier; Again according to numbering and the position display subimage between the subimage and the subimage thumbnail of described definite subimage.
Step 106, when the user chooses current fineness, angle lower part scene and wishes to obtain more high-definition image, shown in the scene domain that the user is chosen that good sub-pictures difference amplifies and show that difference amplifies picture, choose immediate fineness image according to picture size and scope after amplifying, the sub-pictures of the interior described immediate fineness of demonstration amplification back image range is replaced described difference and is amplified picture.
