Character display abnormity detection method and device, electronic equipment and program product

Abstract

The embodiment of the invention discloses a method and device for detecting abnormal character display, electronic equipment and a program product. The method comprises the steps that a first character bitmap and a second character bitmap are obtained through an operation system interface; the first character bitmap and the second character bitmap respectively correspond to different characters; respectively determining color filling rates of the first character bitmap and the second character bitmap; and based on the color filling rates of the first text bitmap and the second text bitmap and a preset corresponding relation, determining whether an abnormality occurs when the text is displayed on the application end. According to the technical scheme, whether the character display is abnormal or not can be detected by utilizing the color filling rate of the character bitmap, the detection mode of the character abnormal display is simplified, the detection efficiency of the character abnormal display is improved, and the character display abnormal problem possibly occurring at an application end can be effectively detected.

Description

technical field [0001] The present disclosure relates to the technical field of image display, and in particular, to a method, device, electronic device and program product for detecting abnormal text display. Background technique [0002] With the development of technology, more and more applications appear. The application side runs on the operating system of the electronic device, and usually uses the native interface of the operating system to implement some functions. Taking an electronic map as an example, when the electronic map displays text, a native interface of the operating system can be used to obtain a corresponding text bitmap, and based on the acquired text bitmap, the corresponding text can be displayed on the electronic map. However, the text bitmap obtained through the native interface of the operating system will change as the user changes the system settings. For example, the user can change the default font of the system to the color font through the s...

Problems solved by technology

However, the text bitmap obtained through the native interface of the operating system will change as the user changes the system settings. For example, the user can modify the default font of the system to a colored font through the setting interface provided by the operating system, or set it to add a font In this case, the electronic map uses the native interface of the operating system to obtain the text bitmap, and after secondary processing of the text bitmap, there will be problems such as blurred text; and in some cases, when the user operates When the setting interface provided by the system uses a special font, the text bitmap obtained by the electronic map through the native interface of the operating system is wrong, because the operating system itself may not support the font
