Referring to Fig. 1, Fig. 1 is the flow diagram of the application format data stream file measurement first embodiment.Wherein,
Format data stream file, which is that we are common, sees figure instrument, when CAD diagram paper is converted into format data stream file, sometimes
Need measurement just to seem more troublesome, there is presently provided a kind of method of format data stream file measurement, and specific format number
The method measured according to stream file comprises the following steps：
S10, marks at least 2 points on format data streaming file；
In the particular embodiment, if necessary to measure the distance between arbitrary point and point on format data stream file, then
Need at least to mark at 2 points, the area if necessary to measure figure on format data stream file then at least needs 3 points of mark, marks
Remember at least 2 points on format data stream file.
S11, calculates the drawing distance between institute's mark point under current ratio.
In step S11, calculating the distance between arbitrary point on format data stream file needs to realize by its resolution ratio.
Referring to Fig. 2, Fig. 2 is the another embodiment of the application, but it is built upon on the basis of Fig. 1 steps S11, step
S11 further comprises following sub-step：
S111, calculates the pixel distance on format data stream file in institute's mark point between every 2 points under current ratio.
In the present embodiment, current ratio refers in being marked to 2 points and calculate the current format of pixel distance
Under ratio at data streaming file, including：Original scale, under magnification ratio and under diminution ratio, wherein, original scale
Refer to that current format data stream file and actual range engineer's scale are 1：Ratio when Y, magnification ratio refer to relatively primitive ratio
The lower amplification of example, diminution ratio refer to reduce under relatively primitive ratio.
In one application scenarios of the application, it is necessary to obtain it when user checks format data stream file
In 2 points of distance, so as to extrapolate the size of the actual range between 2 points.Since format data stream file is to carry out
Corresponding multiple zooms in or out, if simple go the distance between 2 points of calculating to be easy to miss by drawing distance
Difference, just needs to measure by a relatively-stationary value here, that is, resolution ratio (can be shown on fixed size screen
Pixel how much).
Further, the format data stream file under current ratio, user need to know two on format data stream file
The direct distance of point, first has to be marked at 2 points, and just 2 points are marked, then according to 2 points of position, meter
Calculate the pixel distance between 2 points.
Refering to Fig. 3, Fig. 3 is an embodiment schematic diagram in Fig. 1, that is, distance between two points measure in the application
Schematic diagram.
In this example, it is assumed that to calculate A on format data stream file, the pixel distance between 2 points of B is right first
A and B points are marked, and then calculate the pixel distance between A points and B points, in the present embodiment, between 2 points of A and B
Pixel distance be X, but in other cases, it may be possible to three points, four points, or even the distance between multiple points.
S112, according to the resolution ratio of the pixel distance between every and the format data stream file, calculates between every
Drawing distance.
According to the resolution ratio of every 2 points of pixel distance and current format data stream file between institute's mark point, calculate
Drawing distance between 2 points.
Alternatively, according in the case of different resolution pixel distance and drawing distance have different formulas, in this reality
Apply in example, screen resolution uses 72dpi, and at this time, pixel distance and the formula of drawing distance are：1 centimetre=28.346 pixels,
Namely drawing distance (cm)=pixel (pi)/28.346, but in other embodiments, such as when resolution ratio is preset as 300dpi
When, pixel distance and the formula of drawing distance are at this time：1 centimetre=118.11 pixels, that is to say, that drawing distance (cm)=as
Plain (pi)/118.11, certainly, screen resolution is not construed as limiting herein.
Such as calculate A, the drawing distance between B points can obtain A according to step S10, and the pixel distance between 2 points of B is
X, can calculate A, 2 drawing distances of B are according to the preset relation between the drawing distance and pixel distance of point-to-point transmission：X/
28.346(cm)。
S12, the actual range between institute's mark point is calculated according to the engineer's scale of drawing distance and format data stream file.
After the distance of the drawing between 2 points is obtained, according to the drawing of format data stream file and the preset ratio of actual object
Ruler can calculate the actual range between 2 points.
In the present embodiment, the preset ratio ruler of drawing distance and actual object when format data stream file is drawn is 1：
Y；So according to the A obtained in step S11,2 drawing distances of B can then calculate A, the actual range between 2 points of B,
In the present embodiment, the actual range between 2 points of A, B is：Y*X/28.346(cm).
In the above embodiment, by calculating the pixel distance between marked in format data stream file two points, pass through
Pixel distance and the relation of drawing distance obtain drawing distance under different resolution, then according to drawing distance and actual range
Engineer's scale relation, obtain actual range.
Referring to Fig. 4, Fig. 4 is the flow diagram of the application format data stream file measurement second embodiment.
In practical operation, when user needs to know in format data stream file the distance between less component,
But if with current format data stream file scale marker, in fact it could happen that error occurs in mark position, can not be accurately
The point of measurement, then need further to be amplified format data stream file, user can be accurately right required for being tagged to
The point of required measurement is marked, and the present embodiment according to preset ratio in format data stream file exactly when being amplified place
During reason, the algorithm of actual range between 2 points.
S20, marks at least 2 points under current magnification ratio on format data stream file.
In the case where format data stream file amplifies, currently at least 2 points are marked.S21, calculate it is every 2 points it
Between pixel distance, wherein pixel distance and format data stream file have identical amplification factor.
After it marked at wherein 2 points, the pixel distance between marked 2 points is calculated, further, due to current
Format data stream file is amplification, meanwhile, pixel distance also has identical amplification factor with format data stream file, so
Record current amplification factor.
S22, according to the resolution ratio of format data stream file and the pixel distance of point-to-point transmission, calculate drawing between 2 points away from
From.
Further, it is assumed that marked two points of pixel distance under the current magnification ratio of format data stream file is
Max, it is P to record current format data stream file amplification factor, in the calculation, that is to say, that pixel distance is also exaggerated,
But resolution ratio does not change, then the ratio of drawing distance and pixel distance is again without change, being marked at this time
Drawing distance between 2 points is：Max/28.346(cm).
S23, the actual range between 2 points is calculated according to the current engineer's scale of format data stream file.
But since format data stream file at this time is in amplification, and amplification factor is P, then pixel distance also can
Therefore P times of amplification, that is, drawing distance can also amplify P times, and with regard to current magnifying state format data stream file and
The engineer's scale of actual object can be amplified accordingly, since the engineer's scale of initial format data stream file and actual object is
1：Y, and format data stream file amplification factor is P, then currently the engineer's scale of amplification format data streaming file and actual object becomes
For：P：Y, that is to say, that the actual range between 2 points marked under current amplification factor is (Y*Max)/(P*28.346)
(cm)。
In the above embodiment, by amplifying format data streaming file, can more accurately to required calculating extremely
Few 2 points are marked, and then pass through amplification factor and pixel distance and the ratio of drawing distance, and drawing distance and reality
The engineer's scale relation of border object, calculates at least 2 points of amplified current format data stream file mark between 2 points
Distance.
Refering to Fig. 5, Fig. 5 is the flow diagram that the application format data stream file measures the 3rd embodiment.

But due to the restriction of drawing, may be under current ratio, can not be 2 points of complete measurement required for mark, at this time,
With regard to needing to reduce current format data stream file.And the present embodiment be exactly when in format data stream file according to default ratio
When example reduce processing, actual range between on drawing 2 points is calculated.
S30, marks under current diminution ratio 2 points on format data stream file.
In the case where format data stream file reduces, currently at least 2 points are marked.S31, calculates between 2 points
Pixel distance, wherein pixel distance and format data stream file have identical minification.
After it marked at wherein 2 points, the pixel distance between marked 2 points is calculated, further, due to current
Format data stream file is diminution, meanwhile, pixel distance also has identical minification with format data stream file, so
Record current minification.
S32, according to the resolution ratio of format data stream file and the pixel distance of point-to-point transmission, calculate drawing between 2 points away from
From.
Further, it is assumed that marked two point of pixel distance of the format data stream file currently under diminution ratio be
Min, it is P to record current format data stream file minification, in the calculation, that is to say, that pixel distance is also reduced,
But resolution ratio does not change, then the ratio of drawing distance and pixel distance is again without change, being marked at this time
Drawing distance between 2 points is：Min/28.346(cm).
S33, the actual range between 2 points is calculated according to the current engineer's scale of format data stream file.
But since format data stream file at this time is in diminution, and minification is P, then pixel distance also can
Therefore reduce P times, that is, drawing distance can also reduce P times, and with regard to current deflated state format data stream file and
The engineer's scale of actual object can be reduced accordingly, since the engineer's scale of initial format data stream file and actual object is
1：Y, and format data stream file minification is P, then currently reduces format data streaming file and the engineer's scale of actual object becomes
For：1：Y*P, that is to say, that the actual range between 2 points marked under current minification is (P*Y*Max)/28.346
(cm)。
, can be more by carrying out diminution processing according to preset multiple to format data stream file in the above embodiment
Comprehensively at least 2 points of required calculating are marked, then passes through minification and pixel distance and drawing distance
Ratio, and drawing distance and the engineer's scale relation of actual object, calculate the current format data stream file mark after reducing
At least 2 points in the distance between 2 points.
