Show the alpha channel of an image as a checkerboard pattern
ResourceFunction["ShowAlphaChannel"][img] highlights an image’s alpha channel using a checkerboard pattern. | |
ResourceFunction["ShowAlphaChannel"][img,c] highlights an image’s alpha channel using a checkerboard pattern with contrast c. |
ShowAlphaChannel will show partial transparency with a transparent checkerboard:
| In[1]:= | ![]() |
| Out[1]= | ![]() |
| In[2]:= |
| Out[2]= | ![]() |
ShowAlphaChannel can be applied directly to AnimatedImage expressions:
| In[3]:= | ![]() |
| In[4]:= |
| Out[4]= | ![]() |
The level of transparency of the checkerboard can be controlled:
| In[5]:= | ![]() |
| In[6]:= |
| Out[6]= | ![]() |
| In[7]:= |
| Out[7]= | ![]() |
In a typical image, it is impossible to see the difference between white and alpha channel transparency:
| In[8]:= | ![]() |
ShowAlphaChannel distinguishes the two:
| In[9]:= |
| Out[9]= | ![]() |
An image with no alpha channel will not be changed by ShowAlphaChannel:
| In[10]:= | ![]() |
| Out[10]= | ![]() |
