SYSTEM AND METHOD FOR BROWSER SIDE COLORIZING OF ICON IMAGES

摘要

A computer system and computer-implemented method colorizes a UI component image on the browser side. A data provider in the system encodes the UI component image into a Base64 character sequence which includes a header part and an image data part; generates Base64 header parts for specified colored versions of the UI component image; and transfers the encoded UI component image and the Base64 header parts for the specified colored versions of the UI component image to a client icon composer. The header part has a fixed amount of characters and the image data part has a variable amount of characters. The client icon composer replaces the header parts of the encoded UI component image with the Base64 header parts for the specified colored versions of the UI component image; and transfers the specified colored versions of the UI component image to a web page/application.

1. A method for browser side colorizing of a user interface (UI) component image, the method comprising:
providing, by a processor, a base64-encoded image string having a header part and an encoded image,
the header part contains a color palette for a user interface (UI) component,the encoded image is image data for the UI component, in a color indexed image format which indexes colors into the color palette in the header part; providing, by the processor, for the header part, plural different color palettes corresponding respectively to plural different colored versions of the UI component; and controlling, by the processor, the color of the UI component by switching content of the color palette in the header part of the base64-encoded image string to one of the plural different color palettes which corresponds to a different colored version of the UI component.
