Embodiment
Below in conjunction with accompanying drawing, the embodiment of invention is further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
Fig. 1 shows a kind of schematic flow sheet adding the method for mirror image based on binary stream that one embodiment of the invention provides, and comprising:
S101, use IMAPI or SCSI engine read optical file information, and arrange the first label information in the first original image;
S102, obtain file to be added and/or file, and according to described first label information and ISO9660 agreement in the mode of binary stream by file to be added and/or described first original image of file write.
Traditional mirror image append file and/or file divide following flow process: the file that original image 1-> will add and/or file-> extract fileinfo in mirror image 1 and data and the fileinfo that will add and combine and generate mirror image 2 – > and delete mirror image 1, be mirror image 1 by the name nominating of mirror image 2, above flow process in the fileinfo reading mirror image 1 and data procedures, can be lost time in a large number.And the flow process of the present embodiment append file and/or file is: the file that original image 1-> will add and/or file-> directly add file and/or file clips to mirror image 1 thus improves formation efficiency.
The present embodiment can efficiently append file and/or file, especially in a large image file, removes an additional small documents, thus saves writing time, improve CD burning efficiency.
As the preferred version of the present embodiment, comprise before step S101:
S100, according to ISO9660 agreement, file to be written and/or file are write the second original image in the mode of binary stream, and by described second original image imprinting to CD.
The present embodiment provides the generation of original image, and directly utilizes original image append file and/or file.The disc of not closing for non-NULL can make additional mirror image, and directly adds file at mirror image.
Particularly, step S100 comprises:
Second label information is set in the second original image, and in described second original image, writes file to be added and/or file in the mode of binary stream according to described second label information and ISO9660 agreement.
Further, step S102 comprises:
By described first original image of file encryption to be added write.
Traditional mirror image generates and just utilizes agreement directly file generated iso file; do not consider the security of file content; the easy like this information that causes is revealed; and the present invention can directly in generative process; to file or mirror image encryption, mirror image can not be opened, need decipher could be viewed; image file content is not illegally browsed, protects the security of information.
Further, step S102 comprises:
Add disc management information in file to be added and/or file, and in the mode of binary stream, described disc management information is write described first original image according to described first label information and ISO9660 agreement.
Traditional mirror image generates, founder can not increase some specific informations to mirror image, when CD or mirror image are too much difficult to management, the management information of oneself can be added, such as when by whom created, what the object created is, these information of the CD produced like this or mirror image Portable belt, facilitate supvr to manage.
Fig. 2 shows a kind of structural representation adding the device of mirror image based on binary stream that one embodiment of the invention provides, and comprising:
Original image read module 11, for using CD burning development interface IMAPI or small computer system interface SCSI engine to read optical file information, and arranges the first label information in the first original image;
Original image adds module 12, for obtaining file to be added and/or file, and in the mode of binary stream, file to be added is write described first original image according to described first label information and ISO9660 agreement.
The present embodiment can append file and file in batches efficiently, especially in a large image file, removes an additional small documents, thus saves writing time, improve CD burning efficiency.
As the preferred version of the present embodiment, also comprise:
Original image writing module, for writing second original image by file to be written and/or file in the mode of binary stream according to ISO9660 agreement, and by described second original image imprinting to CD.
Particularly, described original image writing module also for:
Second label information is set in described second original image, and in described second original image, writes file to be added and/or file in the mode of binary stream according to described second label information and ISO9660 agreement.
Further, described original image add module also for:
By described first original image of file encryption to be added write.
From the information security angle of user, just the data in mirror image are encrypted in this step of mirror image as much as possible, thus effective guarantee user information safety.
Further, described original image add module also for:
Add disc management information in file to be added and/or file, and in the mode of binary stream, described disc management information is write described first original image according to described first label information and ISO9660 agreement.
Directly from the angle of user management CD, just can add information from this step of making mirror image, so that by information burning on CD, be convenient to the management of CD.
Meanwhile, when imprinting mirror image, as long as imprinting mirror image in order, just can copy, and do not need to extract CD content or make CD mirroring to copy, improve optical media replication efficiency.Utilize once by the mirror image of imprinting in disc, additional mirror image can on new building copy data content.Can copy information quickly, thus save time cost.
The present embodiment for core, by being bridge to the process of additional mirror image, thus the protection of the convenient management that stores file and fileinfo, and ensures practicality with iso9660 agreement as much as possible.
In order to a kind of device adding mirror image based on binary stream that the present embodiment provides is described better, below the using method of this device is further described:
As a kind of mirror image adding the device generation of mirror image based on binary stream that Fig. 3 provides for the present embodiment; Fig. 4 is that the present embodiment adds file on the basis of original image; Fig. 5 is the design sketch after the present embodiment adds file on the basis of original image; Fig. 6 is that the present embodiment adds file on the basis of original image; Fig. 7 is the design sketch after the present embodiment adds file on the basis of original image; Fig. 8 is the mirror image after the present embodiment adds file and file; Fig. 9 is that the present embodiment adds mirror image in original image; Figure 10 is that the present embodiment to add after mirror image imprinting to the design sketch of CD; Figure 11 is the design sketch that the present embodiment is opened same mirror image encryption front and back decompression tool.
In instructions of the present invention, describe a large amount of detail.But can understand, embodiments of the invention can be put into practice when not having these details.In some instances, be not shown specifically known method, structure and technology, so that not fuzzy understanding of this description.
