Abstract
The invention discloses a method and a device for converting file formats. The method for converting the file formats is used for converting a PostScript file into a PDF file and comprises the following steps: determining that a vector path set of one PostScript format file contains a character path set and a graph path set, wherein the character path set is correspondingly provided with a character object in the PostScript format and the graph path set is correspondingly provided with a graph object in the PostScript format; recording parameter information correlated with the character object in the PostScript format in variables of the vector path set; converting the character object in the PostScript format into a character object in the PDF format on the basis of the parameter information; and the converting the graph object in the PostScript format into the graph object in the PDF format.
Description
Technical field
The application relates to the electronic document process field, relates in particular to a kind of method and device of document format conversion.
Background technology
The PDF document has become in many electronic format documents at present, and is most widely used a kind of.In printing and printing field, the PDF document occupy dominant position especially, no matter be that front end is set type or rear end output, PDF is the standard format that content of pages is described document.
On the other hand, Adobe is before the PDF document is used, the standard format that the content of pages of definition is described document is PostScript, although PostScript has many deficiencies in page independence and equipment related fields for the PDF document, but because the long applicating history and abundant periphery support of PostScript, so there is the user of One's name is legion still using the PostScript form to print and printing.
Because the PostScript format file when handling, can run into a series of troubles, so before output system is done rasterization process before the PostScript format file being submitted to seal, need earlier through standardization processing.Being about to the PostScript format conversion is PDF.
In the standardization processing of PostScript formatted file, important target is the original description type of conservation object as far as possible in the process of conversion.After conversion, remain literal object among the PDF as the literal object among the PostScript, Drawing Object among the PostScript also remains the Drawing Object among the PDF after conversion, image object among the PostScript also remains image object among the PDF etc. after conversion, original looks and the device independence that can keep page-describing so to greatest extent, thereby the design idea of end subscriber before reproducing as far as possible truly.For the literal object, optimal situation is to remain the literal object after conversion, and descriptive text presents the outline data of shape and control data and all kept completely, has not a particle of loss.
The present conversion method of the literal vector path that the instruction based on the charpath among the PostScript is obtained commonly used comprises following two kinds:
(1) obtain the vector path of literal based on the charpath among PostScript instruction, with fill or the line pattern described, as vector path carry out the graphic plotting operation like that.Just, directly will be converted to corresponding PDF vector path based on the literal vector path that PostScript obtains.
(2) based on the Tr that provides in the PDF object (Text rendering mode, literal drawing mode) attribute, the vector path of the PostScript form that will be obtained by charpath instruction is converted to corresponding PDF literal object.
Yet in the process of technical scheme, the applicant finds that there is following shortcoming at least in prior art in realizing the embodiment of the present application:
(1) because what adopt in prior art one is the technical scheme that directly profile of the literal of PostScript form is converted to corresponding PDF vector path, so exist the technical matters of the control information of having lost literal;
(2) because what adopt in prior art one is directly the profile of the literal of PostScript form to be converted to the technical scheme of corresponding PDF vector path, so exist the technical matters that conversion is inaccurate, may have ghost image.
(3) owing to the Tr attribute that provides in the PDF object that is based on that in prior art two, adopts, the vector path of the PostScript form that will be obtained by charpath instruction is converted to the technical scheme of corresponding PDF literal object, so exist the vector path that obtains for non-charpath instruction, have the technical matters of losing.
Summary of the invention
The invention provides a kind of method and device of document format conversion, in order to solve in the prior art, exist the technical matters that the literal control information is lost or common vector path is lost.
The present invention provides following technical scheme by the embodiment among the application:
