Because there is no photo that the people expects take on mobile phone I (or friend) as material, carry out DIY and operate to create cartoon character on mobile phone or animation background; Particularly consider that mobile phone is far the computing power of weak (desktop computer that only is equivalent to the initial stage in this century) with respect to desk-top computer, also often makes the people step back.
In order for this special platform of mobile phone, to realize the DIY image manipulation, adopted in design following series of measures, particularly reduce the memory requirements of application program:
A. application program is more simply better.We become Midlet by each establishment of component as far as possible, and a plurality of Midlet used are encapsulated in Midlet bag, and this makes the Program Manager of mobile phone can manage more frugally the resource that Midlet and Midlet are used.
B. application program is the smaller the better.Delete the assembly of temporarily not using in application program, reduce unnecessary information, to reduce the volume of whole program as far as possible.When on wireless network, downloading application program, less application program will shorten download time greatly, and can with other application programs on equipment are compatible, move (rather than exclusive).
C. reduce the total memory requirements of application program as far as possible.Major measure has: 1. use less object type, use scalar type (scalar type) instead.Because scalar type takies internal memory still less than object type; 2. lack statement object as far as possible.Because when statement during an object, system will be on the operation heap allocation space, so should when application program is about to use this object, reallocate it, rather than program is all distributed while starting.And, once program no longer needs this object, will be just null to the equal assignment of quoting of this object.3. need the usage data type by precision.Just should use boolean whenever possible, byte, the data types such as short replace int.This details is very micro-on the impact of desktop computer program, but will be with producing the impact taken care of the pence on mobile phone.4. reuse as far as possible.Allow and a plurality ofly quote the different time in life cycle in program and use same object.For example reuse some Large-scale array, reuse and can utilize the runtime storage distributed, use the 'inertia' instantiation.Although this does not meet the soft project principle, be applicable to the reality of the very weak computing equipment of this ability of mobile phone.5. avoid creating object in circulation.6. running check storer service condition.Relevant method has: freeMemory and totalMemory.OutMemoryError mistake by oneself.Should guarantee that application program is when internal memory overflows, have a predetermined routine that exits to manage this, and do not leave operating system for.7. timely releasing resource.To file, network connection etc. resource, when no longer needing to use, don't not account for and putting.Should oneself carry out necessary clear operation, and not rely on garbage collector or host environment.8. use local variables more.In the desktop computer application, the developer is accustomed to setting more class data member, and less use local variable.But the class data member is actually " global variable " in class, is data dispatch, stack manipulation support frequently, is actually and consumes that CPU calculates to support.By the local variable assignment, eliminate the additional step of the data member of access classes, can reduce the CPU treatment capacity of application program.Encapsulate data although lost like this benefit of bringing in class,, for the application program of moving, need mass data on this microminiature computing equipment of mobile phone, at first its processing speed need to be considered.
Beneficial effect:
Cartoon character on mobile phone and background creative method based on the simulation mural painting of the present invention, use simple and practical Digital Image Processing algorithm, note reducing data volume and improve the CPU operational efficiency, make the restricted mobile phone cartoon works on mobile phone screen size and mobile phone computing power can be with cheap creation cost and operational effect fast, for all ages and classes, different levels, cellphone subscriber in different time sections, by what create, the method of easy operating, the former figure of number is changed into to the mural painting design sketch of various different styles on mobile phone, bring more colourful look and joy to cellphone subscriber's life.Will point out especially: realizing DIY image manipulation if one of the object of the invention is weaker than at this software and hardware resources of mobile phone on the platform of computing machine far away, is fully necessary so take in design above-mentioned a series of specific aim measure.
