Method and apparatus for generating two-dimensional barcode picture having dynamic effect

An apparatus for generating a two-dimensional barcode picture having a dynamic effect, comprising:

• a processor, the processor configured to:
• encode a target information set into a two-dimensional barcode sequence;
• obtain a feature bit included in the two-dimensional barcode sequence;
• calculate relative coordinates of the feature bit in a two-dimensional barcode specification matrix;
• map the feature bit to a feature area included in a preset drawing area according to the relative coordinates of the feature bit in the two-dimensional barcode specification matrix;
• and
• display a dynamic animation of a dynamic picture in the preset drawing area by using a canvas component according to a preset animation effect definition, the dynamic animation of the dynamic picture comprising a motion effect that causes the processor to:
• cause a first pixel to have a predetermined grayscale value corresponding to the feature bit mapped to the feature area, and
• in response to an end or a periodic end of the animation effect, cause a second pixel to have a predetermined grayscale value corresponding to the feature bit.

A non-transitory computer readable storage medium, storing computer readable instructions, the computer readable instructions causing one or more processors to:

• encode a target information set into a two-dimensional barcode sequence;
• obtain a feature bit included in the two-dimensional barcode sequence;
• calculate relative coordinates of the feature bit in the two-dimensional barcode specification matrix;
• map the feature bit into a feature area in a drawing area according to the relative coordinates of the feature bit in the two-dimensional barcode specification matrix;
• and
• draw a dynamic picture having an animation effect in the drawing area by using a canvas component according to a preset animation effect definition, the animation effect of the dynamic picture comprising a motion effect that dynamically changes a greyscale value of a first pixel in the feature area based on the preset animation effect definition and a predetermined grayscale value corresponding to the feature bit that is mapped to the feature area, wherein a target image frame of the dynamic picture at an end or a periodic end of the animation effect includes the feature area configured with a second pixel set to the predetermined grayscale value corresponding to the feature bit.
