File attachment method and electronic device thereof

1. A method in an electronic device, comprising:

attaching a file to a first application program during composition of a message after execution of the first application program;

determining whether a content of the attached file is expressible as an image;

selecting and executing a second application program from among a plurality of second application programs based on an extension of the attached file in a background when the content of the attached file is expressible as the image;

generating the image based on the content of the attached file by using the second application program that executes in the background;

terminating the second application program after generation of the image; and

inserting and displaying the content of the attached file by the generated image into a body content of the message.

2. The method of claim 1 , wherein generating the image corresponding to the attached file comprises:

determining whether the second application program for supporting an extension of the attached file is being executed;

executing the second application program in a background when it is determined that the second application program is not being executed; and

generating the image corresponding the attached file by using raw data of the second application program stored in a buffer.

3. The method of claim 2 , wherein generating the image corresponding to the attached file comprises generating the image in a unit of a display buffer in an application buffer of the second application program.

4. The method of claim 2 , wherein generating the image corresponding to the attached file comprises:

determining a number of images for generation of the image corresponding to a number of pages in the attached file; and

generating a number of images equal to the determined number corresponding to the number of pages in the attached file.

5. The method of claim 1 , wherein generating the image corresponding to the attached file comprises:

determining image quality for generation of the image corresponding to the attached file; and

generating the image corresponding to the attached file according to the image quality.

6. The method of claim 1 , wherein inserting the image into the first application program comprises setting a hyperlink associated with the attached file in the image.

7. The method of claim 1 , further comprising inserting the image into a text by using optical character recognition (OCR).

8. The method of claim 1 , further comprising maintaining the image in an inserted state into the first application program when the attached file is deleted.

9. The method of claim 1 , wherein the image includes a number of images corresponding to a number of pages in the attached file.

10. The method of claim 1 , wherein the image includes all content of the attached file.

11. An electronic device comprising:

at least one memory; and

at least one processor configured to:

attach a file to a first application program during composition of a message after execution of the first application program;

determine whether a content of the attached file is expressible as an image;

select and execute a second application program from among a plurality of second application programs based on an extension of the attached file in a background when the content of the attached file is expressible as the image;

generate the image based on the content of the attached file by using the second application program that executes in the background;

terminate the second application program after generation of the image; and

insert and display the content of the attached file by the generated image into a body content of the message.

12. The electronic device of claim 11 , wherein the processor is further configured to:

determine whether the second application program for supporting an extension of the attached file is being executed;

execute the second application program in a background when it is determined that the second application program is not being executed; and

generate the image corresponding the attached file by using raw data of the second application program stored in a buffer.

13. The electronic device of claim 12 , wherein the processor is further configured to generate the image in a unit of a display buffer in an application buffer of the second application program.

14. The electronic device of claim 11 , wherein the processor is further configured to:

determine a number of images for generation of the image corresponding to a number of pages in the attached file; and

generate a number of images equal to the determined number corresponding to the number of pages in the attached file.

15. The electronic device of claim 11 , wherein the processor is further configured to:

determine image quality for generation of the image corresponding to the attached file; and

generate the image corresponding to the attached file according to the image quality.

16. The electronic device of claim 11 , wherein the processor is further configured to set a hyperlink associated with the attached file in the image.

17. The electronic device of claim 11 , wherein the processor is further configured to insert the image into a text by using optical character recognition (OCR).

18. The electronic device of claim 11 , wherein when the attached file is deleted, the processor is further configured to maintain the image in an inserted state into the first application program.
