It wasn't a matter of discussion before you clarified: JPEG. Thank you.In this case, you need to parse EXIF:http://en.wikipedia.org/wiki/EXIF[^].See, for example, this library: http://www.exiv2.org/[^].—SA

If you're talking about the port you plug your monitor into, you do NOT treat it the same way you treat a serial port. The same code will not work.What are you trying to do with this??

You are not getting it. "Color specification" it totally irrelevant to it. You images are really different: motion, lighting, noise, and so on. One second is huge time to make images very difficult on a pixel level. Even nearest frames (no matter what your frame rate is) will be very different...

I found the solution after reading this [^]excellent article.So that parts actually give you the "Date Taken" property, which as Sergey rightly stated, is taken from the EXIF that only JPEG based files have. EXIFINFO exifinfo;memset(&exifinfo,0,sizeof(EXIFINFO));Cexif...

Without saving to disk, there is nothing like .jpg or .png or whatever image file format. Therefore, you don't need to convert anything in this respect.But you need to convert the data you get into something you can work with in memory. I strongly suggest to use the System.Drawing.Image[^]...

The reason the images do not show is because you are linking to them using the file system. Meaning, the path is something like, "C:\intepub\wwwroot\yourapp\docs\filename.jpg"The path needs to be a url because it is the client's browser that will actually request it and needs access to it.

Please see the comment to the question. It depends on the purpose, of course, but for most, your comparison have too little practical sense. I hope I explained why.Now, didn't I tell you before that GetPixel is prohibitively slow? You have to use...

You have to support it in code. Take bounding rectangle and consider two separate cases: if its aspect ratio bigger or smaller then the target one. In one case you can create two vertical unused bands on left and right, on second case — two horizontal bands on top and bottom. The same aspect...
