Screen Capturing in JPG format and not Bitmap
-
I want to make a screen capturing application which captures and stores in JPG or GIF format and not in Bitmap format. I have examples from codeproject but all of them are using Bitmap b'coz of which when i save themin a bitmap file for sending to the server the file size if too much. Thanks & Regards.

You can convert the bitmap to a JPG and then...

Use GDI+ to save to JPG. Once you have a HBITMAP containing the screenshot do Something like this (can't remember the correct objects/methods now so you will have to look them up, but it generally goes something like this):
Gdiplus::Bitmap Img; //or maybe Gdiplus::Image...
Img.Attach(hbitmap_screenshot); //or fromHBITMAP()...
Img.Save(path_to_save_to, Gdiplus::ImageFormatJPEG);
Img.Detach();> The problem with computers is that they do what you tell them to do and not what you want them to do. <

If you are using MFC, you could use
CImage::Save()withImageFormatJPEGorImageFormatGIFas theguidFileTypefield. -

Is there any way I can Optimize the size to somewhere below 100KB as it needs to be sent to the server for real time monitoring. Thanks In Advance
