Writing method and device for handwriting

The invention relates to a writing method and a writing device of handwriting, which select a corresponding preset mode through the comparison between the transverse coordinate distances on the transverse coordinate direction and the longitudinal coordinate distances on the longitudinal coordinate direction of a current sampling point and a former sampling point and basing on the comparison result to carry out transformation for an initial model matrix, and the transformation is carried out according to the decimal parts of the transverse coordinate and the longitudinal coordinate of the current sampling point and the initial model matrix determined according to a preset pen width, and a final transformation matrix after transformation is used for filling the sampling point. Since transformation is carried out to the initial model matrix by adopting the decimal parts which have relatively high precision and the final transformation matrix after transformation is used for filling the current sampling point, th
