Abstract: Embodiments of the present disclosure relate to a method and apparatus for determining a text color. The method may include: determining, in response to detecting a text frame on canvas, a subimage corresponding to the text frame from the canvas; acquiring color values of pixels in the subimage, to determine an average color value of the subimage; determining an average luminance value of the subimage based on the average color value of the subimage; and determining a color of text to be inputted into the text frame based on the average luminance value of the subimage.

Abstract: A method and apparatus for generating a customized visualization component are provided.

Abstract: Embodiments of the present disclosure presents a method and apparatus for generating a customized visualization component. A specific embodiment of the method comprises: determining, in response to receiving a creation instruction for instructing to create a customized visualization component, a visualization instance presented on a current component editing page based on the received creation instruction; determining an initial visualization component corresponding to the visualization instance and a user setting parameter set by a user for the visualization instance; and uploading a creation request for the customized visualization component to a server to enable the server to generate the customized visualization component based on the initial visualization component and the user setting parameter, the creation request including identifier information of the initial visualization component and the user setting parameter.
