Introduction to the CSImageViewer

1. Introduction to the CSImageViewer

3. CSImageViewer classes • MainProgram • CSImageViewer • ImageData • GrayImageData • ColorImageData • pnmHelper • Timer

4. CSImageViewer classes • MainProgram class • file: MainProgram.cs • this class contains the Main() method • do not use directly

5. CSImageViewer classes • CSImageViewer class • file: CSImageViewer.cs • instantiate this class to display an image • refer to doxygen docs: http://www.sju.edu/~ggrevera/cscCV/CSImageViewer/CSImageViewer/CSImageViewer/html/class_c_s_image_viewer_1_1_c_s_image_viewer.html

6. CSImageViewer classes • ImageData class • file: ImageData.cs • class containing the actual pixel data values • note that this class is abstract • refer to doxygen docs: http://www.sju.edu/~ggrevera/cscCV/CSImageViewer/CSImageViewer/CSImageViewer/html/class_c_s_image_viewer_1_1_image_data.html

7. CSImageViewer classes • GrayImageData class • file: GrayImageData.cs • class containing the actual pixel data for a gray image (i.e., only one value per pixel) • do not use directly • refer to doxygen docs: http://www.sju.edu/~ggrevera/cscCV/CSImageViewer/CSImageViewer/CSImageViewer/html/class_c_s_image_viewer_1_1_gray_image_data.html

8. CSImageViewer classes • ColorImageData class • file: ColorImageData.cs • class containing the actual pixel data for a color image (i.e., 3 values per pixel - red, green, and blue (rgb)) • do not use directly • refer to doxygen docs: http://www.sju.edu/~ggrevera/cscCV/CSImageViewer/CSImageViewer/CSImageViewer/html/class_c_s_image_viewer_1_1_color_image_data.html

9. CSImageViewer classes • pnmHelper class • file: pnmHelper.cs • this class contains methods that read and write PNM/PGM/PPM images (color rgb and grey images) • do not use directly • refer to doxygen docs: http://www.sju.edu/~ggrevera/cscCV/CSImageViewer/CSImageViewer/CSImageViewer/html/class_c_s_image_viewer_1_1pnm_helper.html

10. CSImageViewer classes • Timer class • file: Timer.cs • class containing timer (elapsed time) implementation • You may use this class to time your implementation of various algorithms. • refer to doxygen docs: http://www.sju.edu/~ggrevera/cscCV/CSImageViewer/CSImageViewer/CSImageViewer/html/class_c_s_image_viewer_1_1_timer.html

11. CSImageViewer classes • Timer class • Timer () • Timer class ctor. • Timer is started immediately. • void reset () • Reset/restart the time. • The timer continues to run. • double getElapsedTime () • Get the elapsed time (in seconds). • Note that this function does not start/stop/reset the timer. It continues to run. • void report () • Report the elapsed time so far (using a modal dialog box). • While this dialog is up, the timer is paused and resumes when the dialog is dismissed.

12. Summary of image data classes • ImageData (abstract) • GrayImageData (don’t use directly) • ColorImageData (don’t use directly) • pnmHelper (don’t use directly) • So how do we use them to actually read in image data?

13. Summary of image data classes • Homework: • See first CSImageViewer assignment.

14. Notes regarding VC# v10

15. Change settings from Basic to Expert • Tools --> Settings --> Expert Settings

16. Use Configuration Manager (Build --> Configuration Manager) to build either Release or Debug version.

17. Enable console to display output messages.
