JPEGEncoding Property


Description:  Controls the JPEG encoding scheme if ImageSaveFormat is ImageSaveFormatJPEG (0).
Type:  Number (enum/short)
Read/Get
Write/Set:
  
 
 
Remarks:  

If the ImageSaveFormat property is set to ImageSaveFormatJPEG (0) then this property determines the JPEG encoding scheme. 
DBPix supports supports 2 JPEG encoding schemes: standard (sequential) or progressive.   Progressive encoding stores the image in multiple scans of increasing quality which allows a low quality image to be rendered very quickly followed by successively improving scans when the image is being transmitted over a slow communications link.  The final image is identical to an image encoded with sequential encoding at the same quality setting. 
Note that DBPix itself will not render a JPEG image in multiple scans, only the final image is displayed, so this property will normally only be of use in an application where a different viewer is used, such as a web browser in an Internet application.
