Dan Berghult did recently some speed testing with reading images from a database:
I just run some tests:
Case 1: IdxField(1) is a PICT: 14 ticks to process this record 1000 times
Case 2 IdxField(1) is JPG Using build in conversion from JPG 515(!)
Case 3: IdxField(1) is JPG Using JPEGImporterMBS 15(!)
So in my case using your class JPEGImporterMBS is 340% faster then the RB-build function and as fast as when I render the PICT.
Plattform: The test was done on Mac but Appl runs on Mac and Win
Real Studio Version: 2012r2
MBS Plugin Version: 12.5
Database: PrimeBase Data Server (SQL)
Database connection: PrimeBase RS Plugin
The application it self is of image archive type.
So if you like speed, please implement several ways and use the fastest
