问题 I was new to Emgu Cv and i was wondering if someone could let me know how i change Emgu.Cv.Image to System.Image?If there is a need for further explanation, let me know and i will do it.The language i am using is C#. 回答1: You can just use the ToImage() method to get a System.Drawing.Bitmap (which is a derived class of System.Drawing.Image ), so something like this // create an Emgu image of 400x200 filled with Blue color Image<Bgr, Byte> img = new Image<Bgr, byte>(400, 200, new Bgr(255, 0, 0)

问题 I have an XML document (generated by Adobe XFA forms), that contains data like the following: <Position> <PositionBorder> <Title/> <StartDate/> <EndDate/> </PositionBorder> </Position> Since this file is defined elsewhere, I am not at liberty to change the format of the XML that I get.

Remove currency symbols and literals from a string with a price universal solution

由 社会主义新天地 提交于 2019-12-06 21:17:39
I have such examples: USD 10.99 LIR10.99 $ 10.99 $10.99 So the input data may be any 'symbolfloat' or 'symbol float'. I have made something like this: float((str(param[2]).translate(None, '$USDLIR'))) But it can be any world currency, so it must be a universal converter. Remove anything from the string which isn't a digit or a decimal point: import re import locale decimal_point_char = locale.localeconv()['decimal_point'] clean = re.sub(r'[^0-9'+decimal_point_char+r']+', '', str(param[2])) value = float(clean) That will also handle grouping ( $ 1,000.00 ) and different locales. You can remove
