Extracting the Thumbnails and EXIF Information of JPEG Files

This program shows how it is easy to extract information complementary to JPEG files. In particular, it work with the thumbnails, which are easier and more rapid to extract and to recompute.

Extracting this information is even essential because this information makes it possible to direct the photograph correctly. Indeed, certain digital camera manufacturers always place the image in a JPEG file in landscape mode, and offer additional information. EXIF indicates how to turn the image to represent it in the proper orientation.

This program also illustrates the use of MFC architecture to carry out a presentation in the Windows Explorer style within the left-hand window of an arborescent presentation of the files' structure. The right-hand window presents either the thumbnails put in a table, or, in a full window, the selected image.

In this mode, it is possible to present EXIF information relating to the posted image.

It should be noted that, for this presentation, in the table the CListView class is not used because it is a capricious operation with imagettes of larger-size presentations. To finish this illustration, the functions of the impression are to print with the choice of either the table of the imagettes or the selected image in full page mode.
