If I understand you correctly, you have a TIF image on your PC and you want to display it on the 50g? I'd do the following:

- Load the picture into a graphics application on the PC like IrfanView.

- Scale it down to the final resolution for display on the 50g.

- Convert it to black and white. The PC lets you select thresholds and filters to create the best results.

- Feed the converted picture to tif2grop and download it to the 50g.

I tried this several times and it does not come out looking too good on the 50G.. but I am getting better, I made the lines wider and did negative image to make the background white and the lines black. finally it looks ok somewhat.

Hi, have you tried CPicEdit at hpcalc.org? I've had success with that program to convert bitmaps to grobs in the past. Also great for creating pixel by pixel grobs on the PC with zoom level up.

This is a real good program but i keep getting output that is 131 x 680 from it
