Embodiment approach

[0024] It should be noted that in practice, the size of the original image may not be an integer multiple of the tile. At this time, for the convenience of subsequent processing, it is preferable to correct the original image. Figure four Make up edges every week. An implementation method of edge compensation is as follows: Set the width of the image after the edge compensation as PW, and the height as PH, and calculate the edge compensation value according to the following formula:

[0025] PW=W 0 *math.floor(log f (W / W 0 ))

[0026] PH=H 0 *math.floor(log f (H / H 0 )) Formula (3)

[0027] The meaning of math.floor(x) is the largest integer not exceeding x. f is the magnification used to reduce the entire image in the later stage, and the f value can be an integer according to the actual situation. The patching can adopt any desired color, preferably a transparent color; the patching can be made on only one side of the length and width, or it can be evenly patched all around. For...

Abstract

The invention provides a tile map storing and loading method. The tile map storing method comprises the following steps: judging an operation condition: if the operation condition is not qualified, ending, and if the operation condition is qualified, continuing; segmenting a map into tile maps; storing the tile maps by layers; reducing the map; and returning to the step of judging the operation condition. The invention also provides a tile map loading method, which comprises the following steps: storing the map according to the above method; inversely looking up the tiles layer by layer in the stored tile map; and loading the found tiles layer by layer. The tile map storing and loading method can quickly display a fuzzy map, is convenient for users to realize quick understanding and analysis, instantly changes a view, shortens loading time and quickens a browsing speed.

Description

Technical field [0001] The invention relates to the field of image display such as electronic maps and super-large game scenes, and in particular to storage and loading methods for electronic maps and super-large game scene tiles. Background technique [0002] In an application system involving the display of pictures such as electronic maps and super-large game scenes, the usual practice is to divide the entire electronic map, super-large game scenes and other pictures (usually called large pictures) into several pieces of the same size on the server side, and each piece is It is called a tile map. Clients (such as personal computers, mobile phones, iPads, etc.) request map data from the server with screen information, area information to be displayed, etc. The server parses out the tile map numbers that the client needs to display based on this information, and loads these tile maps as a response and sends them to the client. The client assembles the received tile maps into an...
