These are basic operations which generally don't depend on the content of the image. Simple examples and pointers to Python tools. Use libraries even for simple operations.

common problems and operations

readers
RGB values
geometric clipping
transparency and backgrounds
colour scaling and conversions
file formats (esp. JPEG, TIFF)
grayscale
thresholds
colour2gray or colour2monochrome

preferred formats

We convert into these wherever possible.

RGB
PNG
white background / black

image readers

example code to read images

geometric bitmap operations

Tools (or native Python) to:

section clipping,
rotate

90/180 rotation (might be required for text)
non-orthogonal values (interpolation)
