The page document content is divided, and a single color region and a complex color region are obtained; the page content in the single color region is converted into a first format of image suitable for compressing single color content and storing the compressed single color content; the page content in the complex color region is converted into a second format of image suitable for compressing complex color content and storing the compressed complex color content; the document page content is divided on the aspect of the type, different types of the page content is converted into corresponding formats of images, and the display effect of characters and image information in the document page content is guaranteed.
Description
Technical field
The present invention relates to field of information processing, specifically a kind of image conversion method based on document file page contents and system.
Background technology
Format document, be that the space of a whole page presents the fixing electronic file form of effect, the such as document of PDF or CAJ form, presenting of format document has nothing to do with equipment, and when various equipment being read, print or prints, the result that presents of its space of a whole page is all consistent; Therefore, it is possible to show abundant page effect well, but needing some corresponding modules when reading format document resolves it, shows, namely needs a reader, greatly limit the use of format document.Especially in network reading, can not require that user installs reader or ActiveX plug-in unit, therefore, the content of format document directly can only be converted to image, carry out unifying to show in the mode of image.
The space of a whole page element that format document support is enriched very much, comprises a large amount of picture and word, thus causes to provide good bandwagon effect to these space of a whole page elements with single picture format.Such as, when using JPG picture format to change format document, because JPG compression scheme can not process the less region of color or process solid color regions well, the word segment display effect in format document can be caused not good; Equally, when using PNG to change format document, generally first color sampling can be carried out, and then carry out Lossless Compression, in the process of color sampling, for reducing data volume, a considerable amount of color value can be lost, cause the image display distortion enriching color comprising after final decompress(ion).
