Meat and fish dishes compiling rule is mixed according to predetermined binary code, the binary code of the binary system picture file is carried out
Mixed meat and fish dishes compiling, to obtain object binary code；
The file under the object binary code to predetermined store path is loaded, is deleted under the store path
Object binary code in the file.
The specific implementation process of computer readable storage medium of the present invention, with above-mentioned electronic device and based on mixed meat and fish dishes two into
The specific implementation process of the image deletion method of code processed is similar, and details are not described herein.
By above-mentioned analysis it is found that computer readable storage medium proposed by the present invention, by needing to delete in picture library
The picture file removed carries out coded treatment, to generate corresponding binary system picture file；It is mixed according to predetermined binary code
Meat and fish dishes compiling rule carries out mixed meat and fish dishes compiling to the binary code of the binary system picture file, to obtain object binary code；Load
File under the object binary code to predetermined store path, is deleted under the store path in the file
Object binary code.Can make delete picture file be not easy to restore, improve because disk leakage due to existing for security risk.
Through the above description of the embodiments, those skilled in the art can be understood that above-described embodiment side
Method can be realized by means of software and necessary general hardware platform, naturally it is also possible to by hardware, but in many cases
The former is more preferably embodiment.Based on this understanding, technical solution of the present invention substantially in other words does the prior art
The part contributed out can be embodied in the form of software products, which is stored in a storage medium
In (such as ROM/RAM, magnetic disk, CD), including some instructions are used so that a terminal device (can be mobile phone, computer, clothes
Business device, air conditioner or the network equipment etc.) execute method described in each embodiment of the present invention.The above is only of the invention excellent
Embodiment is selected, is not intended to limit the scope of the invention, it is all using made by description of the invention and accompanying drawing content etc.
Structure or equivalent process transformation are imitated, is applied directly or indirectly in other relevant technical fields, and is similarly included in the present invention
Scope of patent protection in.
