v1.0 is released

To specify timing information in terms of frames not of milliseconds, the show_start(end)_frame property is added. To enable the properties, the is_frame property should be also specified as true.

Note that the display duration do not necessarily correspond to the intended value. For examples, see Bridges et al. (2020).

About how to use the show_start(end)_frame property, see the demonstration files.

v0.4 is released

New demos

demos/draw_part_of_image.html

This file demonstrates how to use the drawFunc with an image. The image is preloaded automatically. In this demo, the part of the image is presented, and moved from left to right.

demos/draw_two_images_repeatedly.html
