The JPH format is a wrapping file format that extends the JP2 file format.
Understanding the JPH Format
Here's a breakdown of what the JPH format entails:
-
Extension of JP2: JPH builds upon the existing JP2 structure.
-
Defined by HTJ2K: The HTJ2K standard defines JPH.
-
Purpose: It's designed to provide enhanced capabilities related to color space handling and raw sensor compression.
Key Features of the JPH Format
The JPH format introduces several improvements and additions compared to the standard JP2 format. These include:
- Modern Parameterizable Color Spaces: Supports advanced color spaces that can be customized with parameters.
- Images Without Color Space: Allows for images that do not have any defined color space. This is useful in specific applications where color interpretation is handled separately.
- Custom Color Mappings: Facilitates the use of custom color mappings. This is particularly beneficial for raw sensor compression, where specific color transformations are needed.
In essence, JPH provides a more flexible and powerful file format for handling a wider range of image data and color representations than standard JP2.
