Efficiently read a PNG file from disk and return the image
ResourceFunction["ReadPNG"][file] reads file as a PNG image and returns the image. |
Export a random image as a PNG file:
In[1]:= |
Out[1]= |
Import the file with ReadPNG one hundred times, noting the elapsed time:
In[2]:= |
Out[3]= |
Repeat the same experiment with Import:
In[4]:= |
Out[4]= |
Note how ReadPNG is significantly faster than Import:
In[5]:= |
Out[5]= |
ReadPNG only imports a file as an Image. Import provides many more options:
In[6]:= |
Out[6]= |
PNG importing can be made even faster by using the underlying symbol directly to avoid ResourceFunction overhead:
In[7]:= |
Out[7]= |
In[8]:= |
Out[8]= |
