Question

Hi, i would like to know how to get information of an 'image' and put it on 'C programming'

I would also like to know how to compress the image information and decompress it.

Answer 1

we can get the information of an image on the output through c/c++ by following this steps:-

1. we should install the code block IDE and it should be configured in graphics of c/c++.
2. select a image which you want to insert , give a name and save it.
3. now take a new file in the code block and save the file with .cpp extension.
4. now start writing the code.
5. include the graphics.h,conio.h header files.
6. use initwindow();,readimagefile(); functions.
7. In the initwindow() function we have three parameters they are we need to give the width,height of the window and title of the window.
8. In the readimagefile() function we have to define the image path and its extension and also the size of the image form left,top,right,bottom.
9. #include<graphics.h>
10. #include<conio.h>
11. int main()
12. {
13. initwindow(width of window,height of window"title of window");
14. readimagefile(image path with name and extension"left,top,right,bottom);
15. getche();
16. }

2.how to compress and decompress the data using c language:-

1. #include<io.h>
2. #include<dir.h>
3. #include<dos.h>
4. #include<math.h>
5. #include<alloc.h>
6. #include<conio.h>
7. #include<stdio.h>
8. #include<process.h>
9. #include<fcntl.h>
10. #include<string.h>
11. #include<graphics.h>
12. #include<vprowait.h>
13. #include<vpromenu.h>
14. #include<vprocrc.h>
15. #include<vprotree.h>
16. #include<vprointr.h>
17. Include all these header files and  run the program.Then u will get the output screen with fields including compression,decompression,help,about,date/time.
18. now enter the source which you want to compress,see the properties of the image information and then select the destination type and finally enter the destination and now click on compress the data gets compressed.
19. Now go to the properties and check the size of the data the size of the data gets decreased.
20. In the same way there is the decompression in that enter the source which you want to decompress and see the properties if the image or data and then select the destination type and finally enter the destination and now click on decompress and the data gets decompressed.
21. now go to the properties and check the size if the data the size of the data gets increased.
22. now save the file and then type the following commands to know actually what has happened.
23. dir datacomp*
24. dir datacomp.c
25. dir after.cmp
26. dir original
27. type AFTER.CMP
28. type original
29. type datacomp.c
30. cls
31. exit
32. With all these commands we can come to know what are the changes that had happened during the compression and decompression of the data.
