Hope someone can tell me how to fix it. Here is my steps:(VB 6.0 code)
Code: Select all
........
twain1.TwainSetCurrentPixelType(1)
twain1.TwainSetCurrentBitDepth(8)
twain1.TwainAcquireToImageID(Me.hWnd)
twain1.SaveAsTiff("test1.tif", 6)
twain1.SaveAsJpeg("test2.jpg", 100)
.......
But the test2.jpg(looks no different with test1.tif) is a 24-bit true color image, not a 8-bit gray-scale image? Did I miss something?
