2. PDF/A - Wikipedia

   en.wikipedia.org/wiki/PDF/A

   PDF is a standard for encoding documents in an "as printed" form that is portable between systems. However, the suitability of a PDF file for archival preservation depends on options chosen when the PDF is created: most notably, whether to embed the necessary fonts for rendering the document; whether to use encryption; and whether to preserve additional information from the original document ...

3. List of monochrome and RGB color formats - Wikipedia

   ColorCode 3-D, [21] [22] a anaglyph stereoscopic color scheme, uses the RG color space to simulate a broad spectrum of color in one eye, while the blue portion of the spectrum transmits a black-and-white (black-and-blue) image to the other eye to give depth perception.

   Interactive Forms is a mechanism to add forms to the PDF file format. PDF currently supports two different methods for integrating data and PDF forms. Both formats today coexist in the PDF specification: [38] [53] [54] [55] AcroForms (also known as Acrobat forms), introduced in the PDF 1.2 format specification and included in all later PDF ...

5. Chroma subsampling - Wikipedia

   en.wikipedia.org/wiki/Chroma_subsampling

   This is achieved by encoding RGB image data into a composite black and white image, with separated color difference data . For example with Y ′ C b C r {\displaystyle Y'C_{b}C_{r}} , gamma encoded R ′ G ′ B ′ {\displaystyle R'G'B'} components are weighted and then summed together to create the luma Y ′ {\displaystyle Y'} component.

7. Grayscale - Wikipedia

   en.wikipedia.org/wiki/Grayscale

   To convert a color from a colorspace based on a typical gamma-compressed (nonlinear) RGB color model to a grayscale representation of its luminance, the gamma compression function must first be removed via gamma expansion (linearization) to transform the image to a linear RGB colorspace, so that the appropriate weighted sum can be applied to ...
