Embodiment Construction
[0036] The present invention will be further described below.
[0037] A method for calculating the zoom ratio of pictures, the main components are: a client, used for users to submit wrong content pictures and related data; a server, used for receiving requests from clients, and calculating font height information of pictures according to algorithms, and assembling wrong titles The word information of the question book, and return the assembled word result information to the client.
[0038] Concrete steps of the inventive method:
[0039] Step (1), establish a picture font height set DSA i = {}, font height mode DSB = {};
[0040] Step (2), dividing the picture into n parts according to the ratio;
[0041] Step (3), for each picture block P after cutting i Carry out progressive scanning, 1≤i≤n, calculate the line height A of the text according to the RGB color value of the pixel i , and record the font height in the mode set DSB={{A i , Weight i}}; Weight i Indicates...
