Bitmap problems with T6963 LCD

I'm generating 160x128 bitmaps with MSpaint, converting them with some freeware to display them on my T6963 based LCD.

They work fine as long as I have the LCD jumpered for 8x8 font width.

If I jumper the LCD for a 6x8 font width, the image gets corrupted and compressed against the left side of the screen.

I want a 6x8 font width.

How can I display the bitmaps properly with this 6x8 configuration?

Please advise.

I am not familiar with this particular chip/display, but I will take a guess. I haven't looked at the data sheet, so I may be way off base.

You may have to reformat your bitmap image so that each 6 bits across (horizontally) is in a different byte. The upper two bits of those bytes would be unused. That's gonna take a lot of bit shifting to take a 160 bit line and put it in 27 bytes.

Another alternative is to keep 8x8 mode, and put up your own 6x8 font characters as bitmapped graphics.
