描述----------Description----------
This function draws the mother wavelet associated with an imwd.object — a two-dimensional wavelet decomposition.
此函数绘制与imwd.object - 一个二维小波分解相关的母小波。
用法----------Usage----------
## S3 method for class 'imwd':
draw(wd, resolution=128, ...)
参数----------Arguments----------
参数：wd
The imwd class object whose associated wavelet you wish to draw.
imwd类，其相关的小波，你想画的对象。
参数：resolution
The resolution at which the computation is done to compute the wavelet picture. Generally the resolution should be lower for two-dimensional wavelets since the number of computations is proportional to the square of the resolution (the DWT is still O(n) though).
计算是计算的小波图像分辨率。一般情况下，二维小波的分辨率应该是较低的，因为数计算的决议（DWT仍然是O（N）虽然）的平方成正比。
参数：...
Additional arguments to pass to the draw.default function which does the drawing.
额外的参数传递给draw.default函数做图。
Details
详细信息----------Details----------
This function extracts the filter component from the imwd object (which is constructed using the filter.select function) to decide which wavelet to draw. Once decided the draw.default function is used to actually do the drawing.
此功能提取filter组件imwd对象（使用filter.select功能的）决定所绘制的小波。一旦决定，使用实际做的图draw.default功能。
值----------Value----------
If the plot.it argument is set to TRUE then nothing is returned. Otherwise, as with draw.default, the coordinates of what would have been plotted are returned.
，如果plot.it参数设置为TRUE然后返回任何值。否则，作为与draw.default，什么将被绘制的坐标返回。

注意----------Note----------
If the plot.it argument isTRUE (which it is by default) a plot of the mother wavelet or scaling function is plotted on the active graphics device.
如果plot.it的说法是TRUE（这是默认设置）的母亲的小波或缩放功能的图绘制上积极的图形设备。

实例----------Examples----------
#[]
# Let's use the lennon test image[让我们的的列侬测试图像使用]
#[]
data(lennon)
## Not run: image(lennon)[＃非执行：图像（列侬）]
#[]
# Now let's do the 2D discrete wavelet transform using Daubechies'[现在，让我们做二维离散小波变换，利用Daubechies“]
# least-asymmetric wavelet N=6[至少对称小波N = 6的]
#[]
lwd <- imwd(lennon, filter.number=6)
#[]
# And now draw the wavelet that did this transform[现在提请小波，这是改造]
#[]
## Not run: draw(lwd)[＃不运行：画（LWD）]
#[]
# A nice little two-dimensional wavelet![一个不错的小二维小波！]
