However, the made JPEG image darkens compared with original image. Is it right ?<BR /><BR />jCprops.DIBWidth = Wid;<BR /> jCprops.DIBHeight = Hei*(-1);<BR /> jCprops.DIBBytes = pYCbCr;<BR /> jCprops.DIBPadBytes = 0;<BR /> jCprops.DIBChannels = 3;<BR /> jCprops.DIBColor = IJL_YCBCR;<BR /> jCprops.DIBSubsampling = IJL_422; //?<BR /><BR /> jCprops.JPGFile = pJpegPath;<BR /> jCprops.JPGWidth = Wid;<BR /> jCprops.JPGHeight = Hei;<BR /> jCprops.JPGChannels = 3;<BR /> jCprops.JPGColor = IJL_YCBCR;<BR /> jCprops.JPGSubsampling = IJL_422; //?<BR />// jCprops.JPGSubsampling = IJL_NONE; //?<BR /> jCprops.jquality = JQuality;<BR /> <BR />Is it right ?
