The Design And Implementation Of GIF Create And Share Tool Based On Android

Nowadays, smartphones and tablets is becoming more popular and has become the necessaries of life. Mobile terminal has been the entrance to many products. GIF dynamic effect performance is excellent and is loved by the masses of users. Hand-painted GIF can effectively attract the interest of children, fully exercise the child’s imagination and creativity. However, mobile phone users are still lack of create GIF tools, GIF tools are mainly in PC and need trival operation. Due to the limitation of mobile phone performance, image processing on a mobile phone is not common. This thesis realizes the GIF image synthesis, effectively reduce the amount of calculation and memory footprint of the algorithm at the same time. What’s more, uses filters to beautify the picture and share GIF in the social network.For image filter function, there are three main aspects. Firstly, Select filters for smartphones, give up the filters whose effect is not obvious and need large amount of calculation. Secondly, adjust the filter parameter to reduce the amount of calculation, reduce the effect of filter for the price. Thirdly, optimization algorithm and modified faulty parts. The filter algorithm on the thesis can effectively shorten the processing time, smooth filter and optimize the filter can reduce more than 50%. The algorithms achieve a balance between the performance and display effect.For GIF generating function, this thesis implements GIF compression based on LZW algorithm to effectively reduce the size of the GIF. On the other hand, the thesis process the gif frame by frame, immediate release of resources after the frame dealed, integrate the GIF at last. The method effectively reduce the memory consumption. The method won’t cause memory leaks, and the GIF images generated time frames linear growth.Considering the importance of social networks to APP, the thesis accesses to GuangDianTong and YouMeng platform, make full use of the advantage of the large platform, connected to a large number of high-quality users to solve the peoblem when promote the app. This method can improve the user viscosity, and make the software more convenient and more userful. This thesis solves technical problems, carries on the design and realization on the client and server. Finally, through the test, verify its function and performance meet the project requirements.
