Accompanying drawing explanation
Fig. 1 is the structural representation of picture-storage system described in one embodiment of the invention;
Fig. 2 is the picture schematic diagram after cutting module cutting in picture-storage system described in one embodiment of the invention;
Fig. 3 is the process flow diagram of picture-storage method described in one embodiment of the invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.According to the following describes and claims, advantages and features of the invention will be clearer.It should be noted that, accompanying drawing all adopts the form that simplifies very much and all uses non-ratio accurately, only in order to object that is convenient, the aid illustration embodiment of the present invention lucidly.
The invention provides a kind of picture-storage system, as shown in Figure 1, comprising:
Cutting module 10, for removing invalid block by picture cutting whole into sections;
Compressed textures modular converter 30, for converting compressed textures form to by remaining piece; And
Compression module 40, for compressing the picture of compressed textures form and storing.
In the present embodiment, picture-storage system also comprises flating module 20, is connected between described cutting module 10 and described compressed textures modular converter 30, for carrying out dithering process to picture to be optimized the transparent transition of picture.In a preferred version, described shake module 20 only carries out dithering process to the partial block of effect after cutting whole into sections poor (such as transparent transition effect is poor).The flating algorithm of described shake module 20 can be optimized the transparent transition of image block, improves display effect.
Described invalid block after cutting is the block that transparency is greater than a particular value, namely after to whole image cutting whole into sections, the block that transparency is higher is that content is relatively less, even negligible piece, therefore the implication that removing this partial block can not affect whole picture is expressed, and also can reduce the space shared by file after picture compression simultaneously.In the present embodiment, invalid block can also be the block not having image.The concrete inactive portion which kind of feature to remove image according to, the present invention does not impose any restrictions.As shown in Figure 2, cutting is carried out to former picture 100 and form multiple image block.Image 110 centered by described effective image place, sleazy piece of its periphery is side images 120.Wherein, because side images 120 there is no content, therefore can directly remove; And in the present embodiment, the image block 1 in center image 110 and image block 2 are the block without content formed after cutting, therefore can be judged to be invalid block and remove.After removing the invalid block (image block 1 and image block 2) in above-mentioned side images 120 and center image, remaining active block can convert compressed textures form to through described compressed textures modular converter 30.
Be understandable that, the cutting of cutting module 10 pairs of pictures is less, then the invalid block can removed is more, and the effect reducing shared capacity after compression is better.According to considering size after the precision of images and compression, the size of cutting module 10 cutting image can be set.
In the present embodiment, described compressed textures form is DXT form.Be understandable that, the present invention does not limit concrete compressed textures form, as long as described texture format is the texture format that GPU can identify.The texture format using GPU to identify can improve the speed and efficiency played up, also can reduce texture memory demand simultaneously.Make image when minimum distortion, reach less memory capacity, accelerate process texture being uploaded to texture memory simultaneously.
In the picture-storage system of the present embodiment, the method compressed the picture of compressed textures form is Zlib compression.Certainly, for concrete compressed format and compression method, the present invention is not restricted.
The present invention also provides a kind of picture-storage method, as shown in Figure 3, comprising:
Cutting module is by picture cutting whole into sections and remove invalid block;
Compressed textures modular converter converts compressed textures form to by remaining piece; And
The picture of compression module to compressed textures form compresses and stores.
Optionally, after the described invalid block of removal, by flating module, dithering process is carried out to the partial block that effect in rest block is poor, carry out compressed textures modular converter converts compressed textures form to step by remaining piece afterwards again.
The present invention is when picture, by image by transparency or other feature ablation inactive portion, and press ad hoc rules piecemeal, and reject invalid block by transparency or other features, after converting the view data of final each piece to compressed textures form (such as: DXT form etc.), finally compressed (such as zlib compression etc.) by data compression algorithm again, finally store, reduce the cost stored; Described system comprises image cutting whole into sections module, flating module, compressed textures modular converter and data compressing module.The present invention can reduce picture resource memory capacity, thus reduces capacity and the resource EMS memory occupation amount of game client.Use compressed textures form to raise the efficiency, make image when minimum distortion, reach less memory capacity.In online game, draw separately and memory management after using this method can read picture block, reduce resource EMS memory occupation amount, and the texture format using GPU to identify is raised the efficiency.
Obviously, those skilled in the art can carry out various change and modification to invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
