It is figure of the amplitude according to frequency permutation, x-axis is frequency, and y-axis is amplitude, will identify the frequency of the frequency spectrum and information to be edited of watermark
Spectrum is overlapped so that mark watermark is stealthy in information to be edited, obtains corresponding transmission information.It should be noted that with
Spectrogram can be arranged according to actual conditions in family, select the frequency and amplitude that need.
Step S43, if size relative scale is mismatched with preset ratio, display reminding information, so that user is to mark
Mark watermark after adjustment is pressed default queueing discipline and placed by the carry out size adjusting of watermark, and by information to be edited and described
Mark watermark is overlapped processing.
If size relative scale and preset ratio mismatch, display reminding information, for user to mark watermark into
Row size adjusting, for example, terminal shows " mark watermark cannot be fully displayed in information to be edited, please reduce mark watermark " then
User is identified the diminution of watermark according to prompt message.In when meeting the requirements of watermark of mark, then display reminding information, prompts
User stops adjustment mark watermark, and after the completion of terminal detects the size adjusting of mark watermark, terminal will identify watermark by pre-
If queueing discipline is placed, and information to be edited and the mark watermark are overlapped processing.
It specifically illustrates in the present embodiment and mark watermark location is determined according to the size of mark watermark and information to be edited
