If the display effect is not OK, continue to edit and modify, and then display the effect after conversion.

[0055] Displaying two different types of graphic data on a conventional display and performing a preview and comparison of the display effects facilitates intuitive experience of the display effects of the graphics on the electronic paper. This is an efficient testing method and avoids the need to actually connect to the electronic paper device for each test. Just implant the graphic data type corresponding to the corresponding electronic paper device. The specific conversion between various graphic data types belongs to the prior art and will not be repeated here.

[0056] In the application of electronic paper technology, the demand for making electronic paper image templates is gradually increasing. Traditional image editing tools cannot meet the special needs of electronic paper templates.
