47 | 47 | For now, let's get on with the implicit approach:

91 | 91 | #
|
92 | 92 | # Each inner list represents a pixel. Here, with an RGB image, there
|
93 | 93 | # are 3 values. Since it's a black and white image, R, G, and B are all
|
94 |
| -# similar. An RGBA (where A is alpha, or transparency), has 4 values |

95 | 95 | # per inner list, and a simple luminance image just has one value (and

96 | 96 | # is thus only a 2-D array, not a 3-D array). For RGB and RGBA images,

97 | 97 | # Matplotlib supports float32 and uint8 data types. For grayscale,

|
127 | 127 | # Pseudocolor is only relevant to single-channel, grayscale, luminosity
