📌 In other circumstances, the .PEF basement may concern files generated and opened up in the Portable Embosser Format (PEF) view, an .XML-shaped technique applied to hold, open and maintain braille books in digital electronic layout. At most, the current .PEF logic involves unambiguous embossing clauses and terms. Thus, the following .PEF mechanics permits to store and share digital braille books encoded into an unambiguous exchange representation. Initially, the .PEF specification has been invented and intended to resolve some issues of ambiguity from other braille reading forms, such as ASCII braille. At the actual moment of time, the .PEF extension can be revealed and comprehended by Braille Utile, a specific third-party Java library for certain manipulations with .PEF schema. Besides, the .PEF resources can be generated on the basis of .ODT documents with the assistance of odt2braille, a specific, perfectly tested and adapted plugin for OpenOffice suite of revision 3.0 and subsequent builds.

📌 The primary assignment of the .PEF file schema is a raw camera graphical image generated by Pentax digital cameras. Precisely, the .PEF layout stores all of visual content precisely in the form it was formerly captured by the CCD sensor of the camera, without any color adjustment or outcome compression. Top-level and skillful photographers are used to referencing the .PEF resources as long as they manage to exploit and utilize the higher-quality images in a raw representation. .PEF entry hierarchy is employed by various distinguished Pentax camera models. However, Pentax cameras are able to store specific images in a bit different variations of the source .PEF data shape. For instance, the images stored in the Pentax Electronic layout may also be processed, covered and sustained alongside with .PTX extension instead. The .PEF constitution serves as one of the primary raw image representations exploited by various camera manufacturers and brands.
📌 Generally, the .PEF hierarchy and composition can be opened up and explored by any typical graphical editor, such as Microsoft Photos, Canvas X Pro, Adobe Photoshop, Corel PaintShop Pro, ACDSee Photo Studio, Adobe Photoshop Elements, UFRaw. As long as the peculiar file layout is identified and recognized by macOS system as well, it is reasonable to attempt using Apple Preview, GIMP (with complementary UFRaw add-in preinstalled) or ColorStrokes package, adapted and compatible with all the newest and latest Mac monoblocks and laptops. Linux computers are also able to uncover and extract the .PEF entry schema with the introduction of the GIMP toolset. Additionally, it may be handy to try reviewing the .PEF compound constitution on Android or iOS devices by involving the Adobe Photoshop Express mobile applet, available in Google Play and App Store markets appropriately. In the alternate case, taking into account that the source file record may contain braille books, the Braille Utils package may appear suitable.
