Cant upload Bitmap on 7920

Do you know the proper way to upload a bmp to a 7920?

I tryed with LCD12864 library from DFROBOT, but without any good result.

With LCD Assistant i got random line stripes.
With image convertor if i upload the sample image the upload is OK, if i upload my image the image quite good but not on screen center and in someway disassembled.

Do you know any sure metod to convert and upload bmp to this LCD?

You could use http://code.google.com/p/u8glib/ which supports uncompressed XBM files (can be exported from gimp)

u8glib uploading speed is ridicolous.
