Module specific_channels

How to read arbitrary but specific selection of arbitrary channels. This is not a zero-cost abstraction.

Structs

• CollectPixels
  Specifies how to collect all the specified channels into a number of individual pixels.
• OptionalSampleReader
  Reader for a single channel. Generic over the concrete sample type (f16, f32, u32). Can also skip reading a channel if it could not be found in the image.
• ReadOptionalChannel
  Used to read another specific channel from an image. Contains the previous ReadChannels objects.
• ReadRequiredChannel
  Used to read another specific channel from an image. Contains the previous ReadChannels objects.
• SampleReader
  Reader for a single channel. Generic over the concrete sample type (f16, f32, u32).
• SpecificChannelsReader
  The reader that holds the temporary data that is required to read some specified channels.

Traits

• ReadSpecificChannel
  Can be attached one more channel reader. Call required or optional on this object to declare another channel to be read from the file. Call collect_pixels at last to define how the previously declared pixels should be stored.
• RecursivePixelReader
  A reader containing sub-readers for reading the pixel content of an image.

Type Aliases

• ReadZeroChannels
  Read zero channels from an image. Call with_named_channel on this object to read as many channels as desired.
