Embodiment
Be described in detail below in conjunction with method, the device of accompanying drawing the embodiment of the invention.
An embodiment of the method that formula layout of the present invention is set type as shown in Figure 3, comprising:
S301, one layout region is set.
Described one layout region can be a space of a whole page, an entire paper or a display part.
S302, formula is enrolled character sample to be set type in the mode of formula box, described formula box is provided with display properties.
Described character sample is the word content of needs that computerese is described a slice article of setting type, and described formula can be mathematical formulae, chemical formula, chemical equation and physical expressions etc.Described formula box is image block and the form piece in the character sample, can association attributes be set by the interface of object when coding.The display properties of described formula box comprises attribute placed in the middle.In actual applications, composing person can be provided with the display properties of formula box according to the format needs, such as left-justify or Right Aligns etc.
S303, the character sample is set type, generate full-page proof and be shown to one layout region, described formula box is set type according to display properties and is shown.
Full-page proof is to be shown to the space of a whole page that the user can read after setting type by the character sample as shown in Figure 4, and when setting type the formula box, if the display properties of formula box is an attribute placed in the middle, then the formula box being set type with form placed in the middle shows; If the display properties of formula box is empty, default treatment then, the one's own profession that just the formula box the continued zone of finishing of having set type shows.
Present embodiment enrolls character sample to be set type with formula in the mode of formula box, is shown to one layout region then automatically, and the full-page proof that formation can be read need not manual adjustments layout effect, has improved work efficiency.If will carry out the modification of literal or formula to the zone that composing is finished afterwards, additions and deletions, only need in character sample to be set type, to get final product, the final full-page proof display effect that still can obtain meeting call format, avoided the full-page proof after setting type is carried out part adjustment, might upset space of a whole page layout, the problem that makes the mistake.In addition,, belong to same level, can not produce the problem that the upper strata covers lower floor, when full-page proof shows, can not overlap, further reduced the modification amount because the formula box is set type with alphabetic character.
Among the embodiment of the method that formula layout of the present invention is set type, the step that the formula box is set type and shown according to display properties as shown in Figure 5, comprising:
If the display properties of S501 formula box is an attribute placed in the middle, judge the half whether length of composing has surpassed one's own profession finished in one's own profession.
If the S502 one's own profession has been finished the length of composing does not surpass one's own profession half, the formula box is set type and is presented at the center of one's own profession.
If the length of the length of composing less than described one layout region has been finished in the S503 one's own profession, formula box right character shows by the one's own profession right-hand member.
Existing formula generally has the numbering of a formula after formula, its form is as follows:
A＝B+C (3.2)
Wherein, (3.2) are exactly the numbering of formula " A=B+C ", and in order to meet existing formula typesetting format, in this step, under the prerequisite that formula has shown between two parties, numbering of equation shows by the one's own profession right-hand member.
If the S504 one's own profession has been finished the length of composing surpasses one's own profession half, the formula box shows according to normal composing.
That is, the formula box is continued the set type zone of finishing of one's own profession shows.
Among the embodiment of the method that formula layout of the present invention is set type, the step that the formula box is set type and shown according to display properties can also comprise as shown in Figure 6:
If the quantity of S601 formula box is two or more, and the display properties of first formula box is attribute placed in the middle, judges the half whether length of composing has surpassed one's own profession finished in one's own profession.
If the S602 one's own profession has been finished the length of composing does not surpass one's own profession half, first formula box is set type and is presented at the center of one's own profession, and the remainder formula box shows according to normal composing successively.
If the S603 one's own profession has been finished the length of composing surpasses one's own profession half, all formula boxes show according to normal composing successively.
The method that adopts formula layout of the present invention to set type, can set type out easily and have the formula literal mixing effect that meets certain format, and the composing effect is accurate, attractive in appearance neat, and edit the deletion literal as required arbitrarily, increase literal, revise word attribute, editor's formula content etc., these editors can not change the formula layout of original form.
An embodiment of the device that formula layout of the present invention is set type as shown in Figure 7, comprising:
Unit 701 is set: be used to be provided with one layout region.
Edit cell 702: be used for formula is enrolled character sample to be set type in the mode of formula box, described formula box is provided with display properties.
Display unit 703: be used for the character sample is set type, generate full-page proof and be shown to one layout region, described formula box is set type according to display properties and is shown.
As improvement, display unit 703 comprises as shown in Figure 8:
First judgment sub-unit 801:, be used to judge the half whether length of composing has surpassed one's own profession finished in one's own profession if the display properties of formula box is an attribute placed in the middle.
First carries out subelement 802: if one's own profession has been finished the length of composing surpasses one's own profession half, be used for the composing of formula box is presented at the center of one's own profession.
Improve as another kind, display unit 703 comprises as shown in Figure 9:
Second judgment sub-unit 901: if the quantity of formula box is two or more, and the display properties of first formula box is attribute placed in the middle, is used to judge the half whether length of composing has surpassed one's own profession finished in one's own profession.
Second carries out subelement 902: if one's own profession has been finished the length of composing surpasses one's own profession half, be used for first formula box composing is presented at the center of one's own profession, the remainder formula box shows according to normal composing successively.
More than the concrete workflow of device embodiment is seen the method flow among Fig. 3, Fig. 5, Fig. 6 embodiment, does not do at this and gives unnecessary details.
More than device embodiment enrolls character sample to be set type with formula in the mode of formula box, is shown to one layout region then automatically, need not manual adjustments.
One of ordinary skill in the art will appreciate that all or part of flow process that realizes in the foregoing description method, be to instruct relevant hardware to finish by computer program, described program can be stored in the computer read/write memory medium, this program can comprise the flow process as the embodiment of above-mentioned each side method when carrying out.Wherein, described storage medium can be magnetic disc, CD, read-only storage memory body (Read-Only Memory, ROM) or at random store memory body (Random Access Memory, RAM) etc.
The above; only be the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; can expect easily changing or replacing, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
