Abstract: A method of drawing a handwriting track for an electronic apparatus includes: creating a buffer canvas and a display canvas; acquiring parameter information of a plurality of touch track points; and performing drawing processing on each touch track point of the plurality of touch track points. The performing drawing processing on each touch track point includes: determining a position parameter, size and transparency of each of a plurality of track points to be displayed respectively, based on the touch position parameter and sensing parameter of the each touch track point and those of a predetermined number of touch track points of the plurality of touch track points; and drawing a handwriting track on the buffer canvas based on the position parameter, size and transparency of each of the plurality of track points, and drawing on the display canvas the handwriting track drawn on the buffer canvas.

Abstract: An information display method and apparatus, and a computer-readable storage medium and an electronic device. The method includes: determining a target font category to be written in response to an operation of a user on a display device page; determining a target font conversion model corresponding to the target font category in a model library, wherein the model library including font conversion models corresponding to a plurality of font categories; in response to a writing operation of the user on the display device page, determining a standard word corresponding to the writing operation according to a writing trajectory of the writing operation, and generating an initial bitmap corresponding to the standard word; and converting the initial bitmap of the standard word into a target bitmap corresponding to the target font category using the target font conversion model and displaying the target bitmap on the display device page.
