10.10. DXF at XY

DXF can be loaded in XY frame. This can be performed in different ways:

  1. Loading data from x, y parameters

  2. Loading data from a variable

  3. Loading size from the .dxf file

In the 2. and 3. cases, number of pixels are required.

10.10.1. Loading data from x, y parameters

[2]:

x = np.linspace(-.5*mm, .5*mm, 1024)
y = np.linspace(-.5*mm, .5*mm, 512)
wavelength = 0.6328*um

filename_dxf = 'hatch_polyline.dxf'


t0 = Scalar_mask_XY(x, y, wavelength)
print(t0)

Scalar_mask_XY
 - x:  (1024,),   y:  (512,),   u:  (512, 1024)
 - xmin:       -500.00 um,  xmax:      500.00 um,  Dx:   0.98 um
 - ymin:       -500.00 um,  ymax:      500.00 um,  Dy:   1.96 um
 - Imin:       0.00,     Imax:      0.00
 - phase_min:  0.00 deg, phase_max: 0.00 deg
 - wavelength: 0.63 um

10.10.1.1. Equal size

[3]:

x = np.linspace(-.5*mm, .5*mm, 512)
y = np.linspace(-.5*mm, .5*mm, 512)
wavelength = 0.6328*um

filename_dxf = 'hatch_polyline.dxf'


t0 = Scalar_mask_XY(x, y, wavelength)
t0.dxf(filename_dxf, num_pixels=None, extent=None, units='um', invert=False,
       verbose=False)
t0.draw(scale='scaled')

t1 = t0.RS(z=5*mm, verbose=True)
t1.draw()

Good result: factor 1.63

10.10.1.2. Invert image can also be performed

[9]:

x = np.linspace(-.5*mm, .5*mm, 512)
y = np.linspace(-.5*mm, .5*mm, 512)
wavelength = 0.6328*um

filename_dxf = './hatch_polyline.dxf'


t0 = Scalar_mask_XY(x, y, wavelength)
t0.dxf(filename_dxf, num_pixels=None, extent=None, units='um', invert=True,
       verbose=False)
t0.draw(scale='scaled')

10.10.1.3. Different size

[6]:

x = np.linspace(-1*mm, 1*mm, 1024)
y = np.linspace(-.5*mm, .5*mm, 512)
wavelength = 0.6328*um

t0 = Scalar_mask_XY(x, y, wavelength)
t0.dxf(filename_dxf, num_pixels=None, extent=None, units='um', invert=False,
       verbose=False)

t0.draw(scale='scaled')

10.10.2. Loading data from a variable

[7]:

t0 = Scalar_mask_XY(x=None,y=None, wavelength=wavelength)
t0.dxf(filename_dxf, num_pixels=(1024, 512), extent=(-1000*um, 1000*um, -500*um, 500*um),
                units = 'um', invert = False,  verbose=False)

t0.draw(scale='scaled')

10.10.3. Loading data from .dxf size

num_pixels is always required.

[8]:

t0 = Scalar_mask_XY(x=None,y=None, wavelength=wavelength)
t0.dxf(filename_dxf, num_pixels=(512,512), extent=None,
                units = 'um', invert = False, verbose=False)

t0.draw()
