如何使用c＃编辑python脚本的某个部分 [英] How do I edit a certain part of a python script using c#

问题描述

我在visual studio中有一个项目，可以在鼠标点击时检索2个不同的x，y坐标。然后坐标将显示在文本框中。我还有一个python脚本，可以使用鼠标单击时选取的x，y坐标裁剪面部。我现在面临的问题是，我不知道如何从文本框中获取坐标并将其直接放在python脚本中，而无需打开python脚本并手动更改它。

基本上我现在想要实现的是第二个最后一行代码CropFace位于，eye_left和eye_right坐标可以直接从我的c＃窗体中的文本框中读取并放置在那里。有谁有想法吗？



请帮助，谢谢。

解决方案

输入类似％的代码python脚本中的eye_l％和％eye_r％并执行以下操作：

  string  s = File.ReadAllText（  python文件名这里）。替换（ ％eye_l％， 你的新左值。）替换（ ％eye_r％， 您的新权利值 ）; 
 File.WriteAllText（  python file name here，s）; 

I have a project in visual studio that can retrieve 2 different x,y coordinates on mouse click now. The coordinates would then be displayed in a textbox. I also have a python script that can crop faces using the x,y coordinates that are picked out on mouse click. The problem I am facing now is that I do not have any idea how to take the coordinates from the textboxes and directly place it in the python script without having to open the python script and change it manually.

def Distance(p1,p2):
  dx = p2[0] - p1[0]
  dy = p2[1] - p1[1]
  return math.sqrt(dx*dx+dy*dy)

def ScaleRotateTranslate(image, angle, center = None, new_center = None, scale = None, resample=Image.BICUBIC):

  nx,ny = x,y = center
  sx=sy=1.0
  if new_center:
    (nx,ny) = new_center
  if scale:
    (sx,sy) = (scale, scale)
  cosine = math.cos(angle)
  sine = math.sin(angle)
  a = cosine/sx

def CropFace(image, eye_left=(0,0), eye_right=(0,0), offset_pct=(0.2,0.2), dest_sz = (70,70)):
  # calculate offsets in original image
  offset_h = math.floor(float(offset_pct[0])*dest_sz[0])
  offset_v = math.floor(float(offset_pct[1])*dest_sz[1])
  # get the direction
  eye_direction = (eye_right[0] - eye_left[0], eye_right[1] - eye_left[1])
  # calc rotation angle in radians
  rotation = -math.atan2(float(eye_direction[1]),float(eye_direction[0]))
  # distance between them
  dist = Distance(eye_left, eye_right)
  # calculate the reference eye-width
  reference = dest_sz[0] - 2.0*offset_h
  # scale factor
  scale = float(dist)/float(reference)
  # rotate original around the left eye
  image = ScaleRotateTranslate(image, center=eye_left, angle=rotation)
  # crop the rotated image
  crop_xy = (eye_left[0] - scale*offset_h, eye_left[1] - scale*offset_v)
  crop_size = (dest_sz[0]*scale, dest_sz[1]*scale)
  image = image.crop((int(crop_xy[0]), int(crop_xy[1]), int(crop_xy[0]+crop_size[0]), int(crop_xy[1]+crop_size[1])))
  # resize it
  image = image.resize(dest_sz, Image.ANTIALIAS)
  return image

if __name__ == "__main__":
	image =  Image.open("C:\\right135\\right135(1).jpg")
	CropFace(image, eye_left=(270,260), eye_right=(342,256), offset_pct=(0.3,0.3), dest_sz=(92,112)).save("C:\\right135\\g.jpg")

Basically now what I would like to achieve is the SECOND LAST LINE of code where CropFace is at, the eye_left and eye_right coordinates can directly be read off the textboxes in my c# windows form and placed in there. Does anyone have any idea?

Please help, thank you.

解决方案

Put a code like %eye_l% and %eye_r% in the python script and do the following:

string s= File.ReadAllText("python file name here").Replace("%eye_l%", "your new left value").Replace("%eye_r%", "your new right value");
File.WriteAllText("python file name here", s);
