I have a DS160128CLCD-46 and am using the example ColorGraphicsLCDAdapterDemo with an Arduino Nano and IDE 1.6.4.  The lcd is i2c and the example is unaltered except to set the mode to i2c.  The example compiles/uploads and works for all text mode and graphics modes.  The problem is that none of the bitmap test images display.  Any tips on what to check?

For example this never shows on the screen...

 mydisp.drawBitmap256((SC_W-120)/2,SC_H/2,120,30,digole256);

 In the sample code, the: SC_W=320 and SC_H=240, you need change them to 160 and 128

Thanks!   I was just going to post that I found out that I needed to do that.  Sorry!
