I am using the WinFile() function to print images of certain pages in my project in a bitmap format.  After upgrading from v5.41 to v6.10 the file size of the bitmap images has increased from ~80kb to ~3.5mb. Why has the size of the bitmap images increased?  

The larger file size seems to be because the bitmap images are no longer being compressed. Citect has confirmed this to be a problem in CitectSCADA version 6.0 to v7.0. We are researching this problem and will post new information here as it comes available.

A suggested work around would be to use the WinPrint() function to print the image in a PDF document using a PDF printer, which would create an image in a pdf format ~125kb in size and does show any loss in image quality.

Here is an example of the WinPrint() function which can be used to print a pdf document. WinPrint("\\dir of cutepdf printer",0,0,0).

The PDF printer 'cutepdf' can be found here >> . We recommend that you test this method before applying to a 'Live' environment.
