JP2 What is JP2 File Format
JPEG 2000 (JP2) is an image coding system and state-of-the-art image compression standard. Designed, using wavelet technology JPEG 2000 can code lossless content in any quality at once. Moreover, without any substantial penalty in coding efficiency, JPEG 2000 have the capability to access and decode the same content efficaciously into a variety of other resolutions and qualities. The code streams in JPEG 2000 is significantly scalable having regions of interest that provide the facility for spatial random access. Possessing Up to 16384 diverse components with the dimensions in terapixels, and precision that can be high as 38 bits/sample.Read More
Searchable PDF What is Searchable PDF File Format
Searchable PDF files retain the original scanned image for viewing, as well as OCR text in a hidden layer that can be used for full-text searches within a document or highlighting text for copy and paste operations. Full OCR conversion to PDF, not including the original image, will never retain 100% of the original formatting, especially if the document has many images or a complex layout.Read More
