TJPEGImage.Performance Property

Controls the trade-off between color quality and speed of decompression.

Pascal
property Performance: TJPEGPerformance;
C++
__property TJPEGPerformance Performance;

Use Performance to set the performance of the jpeg image when reading, that is, for decompressing files. This property is not used for writing out files. 

Performance affects the display of the internal bitmap image. This image is a 256-color bitmap. Setting Performance to jpBestSpeed may cause some dithering in the bitmap image.
