Step S100, the map label information data in the read electric map;
Preferably, described map label information data, include but not limited to word row mark mode, mark the wire key element, the mark text.
Step S200, judge detection to the map label information data, and according to judged result, the mark text is carried out to the putting position processing.
As shown in Figure 2, as a kind of embodiment, described step S200 comprises the steps:
Step S210, judge whether word row mark mode adopts geese flying in a line-brothers or flexing word row mark mode; If not, enter step S270; If choice for use geese flying in a line-brothers/flexing word row mark enters step S220;
In the word row mark mode of electronic mapping, word row mark mode comprises the Four types such as horizontal word row, vertical word row, geese flying in a line-brothers word row, flexing word row, its concrete form of expression is as shown in Fig. 3 a ~ 3d, and the arrow in Fig. 3 a ~ 3d means the trend that annotation is read.
To the word row mark mode in the map label information data, judge whether to adopt geese flying in a line-brothers or flexing word row mark mode; If not, enter step S270, process according to existing common text disposing way by the content of mark text; If choice for use geese flying in a line-brothers/flexing word row mark enters step S220, further process;
Step S220, detect the wire key element of current mark and whether can hold the content that marks text, if the wire key element can't be held the content that marks text, exits the mark process of this key element, finishes to return; If so, enter step S230;
Step S230, after the mark spatial dimension meets the demands, whether be Chinese, if marked content is not Chinese, enter step S270 if detecting the mark text; If marked content is Chinese, enter step S240;
Step S240, whether detect wire key element corresponding to mark text has the position of putting the mark text; If nothing, finish to return; If have, enter step S250;
Step S250, whether the position that text is put in judgement is single sub-line segment, and if so, the content that will mark text is placed on this single sub-line segment, and the inclination angle of the single sub-line segment that directly calculating mark text is put, then enter step S260; If not, the position of putting text is a plurality of sub-line segments, calculates respectively the inclination angle that each line segment mark text is put, and then enters step S260;
Step S260, the inclination angle of the sub-line segment in judgement mark text place, as fruit line segment inclination angle is greater than the threshold value that the user sets in advance, (sub-line segment inclination angle is greater than threshold value and refers to for given inclination angle threshold alpha, in sub-line segment and plane coordinate system, the angle theta of X-axis forward meets the requirement of α≤θ≤180-α), to all mark text prefix rotations on this sub-line segment, making it with marking sub-line segment angle was 0 (mark prefix and Y-axis positive dirction are 90-θ degree angle), and the order of the content of transposing mark text, by the mark text content respectively mean allocation be placed on single sub-line segment or a plurality of sub-line segment, end is returned.
Preferably, the threshold value that described user sets in advance is 30～60 degree angles, and can dynamically adjust the scope of threshold value;
More preferably, the threshold value that described user sets in advance is miter angle.
Like this, when showing the mark text user's experience better, more meet the mark requirement of electronic mapping.
A wire key element may be to consist of a plurality of sub-line segments, and this situation is more common for atural objects such as river and mountain ranges the time.If threshold value is 45 degree, as shown in Fig. 4 a, the wire key element comprises 3 points (a, b, c), 2 sub-line segments, the trend of line segment be a to b, b is to c.In the time of mark, selected labeling position lays respectively at sub-line segment ab and sub-line segment bc from upper, in this case, although line segment ab inclination angle in the horizontal direction is greater than threshold value, but because the inclination angle of the horizontal direction of bc section is 23.5 degree, be less than threshold value, so the mark prefix still adopts the mode that vertically is marked line segment on the whole.With respect to Fig. 4 a, in Fig. 4 b, the inclination angle of two sub-line segments all is greater than threshold value, so the mark of this wire key element is used the mark text to rotate and is inverted the mark text, guarantees order from top to bottom.In order to guarantee the consistance of Dimension style, for the mark text across a plurality of line segments, as long as there is the inclination angle of a sub-line segment to be less than threshold value, this mark text is not applied the rotation transposing.
Need the threshold value that sets font and rotate in process by the geese flying in a line-brothers in the electronic mapping system/flexing word row mark, at first need to calculate the angle of current key element and horizontal direction, if be greater than the threshold value that the user arranges, to make it with the sub-line segment angle in marking line place be 0 to rotation rotation prefix, and transposition mark order.Otherwise keep direction vertically to get final product.
