Preferably, the processing method of the picture processing in the second step is as follows: the method comprises the steps of firstly analyzing picture information, compressing a picture without cutting, using a used compression tool which is pngquant, using a modified version of a median cutting quantization algorithm and an additional technology to reduce the defect of median cutting by the pngquant, selecting a box to minimize the variance of the median, and establishing a histogram on the basis of a basic perception model, so that the weight of a noise area of the picture can be reduced, and using Voronoi iteration to correct colors, thereby ensuring the locally optimal color palette, wherein the pngquant works in a pre-multiplied alpha color space, the weight of transparent colors is reduced, and when remapping is carried out, error diffusion is applied to a plurality of adjacent pixels to quantize the pixels into an area with the same value to remove edges, so that the area that the visual quality is increased under the condition of no dithering is avoided.
Preferably, in the process of improving color, the histogram is adjusted in a process similar to gradient descent by: the median cut was repeated multiple times, adding weight to the underperforming color.
Preferably, for the pictures to be cut, the pictures are cut by java first and then compressed. And for some pictures which cannot come out due to three-dimensional rotation and the like, the content is recompiled into the pictures through a windows machine.
(III) advantageous effects
The invention provides a document conversion method. The method has the following beneficial effects:
(1) the network micro-class recorder is suitable for manufacturing courseware in enterprise training, schools, training institutions and the like, a person who does not know the technology can quickly manufacture a network micro-class through h5 and recording, and a user only needs to understand manufacturing documents, so that the courseware recording efficiency is greatly improved.
