Open BDF File

The BDF file extension, short for "Bitmap Distribution Format," is a file format that stores bitmap font files. These files contain font information, such as glyph data and character spacing, necessary for displaying text in various applications. The primary purpose of this article is to provide an overview of the different formats and ways to open, use, or convert files with the BDF extension. Additionally, we will explore alternative uses for the BDF extension and provide information on resources and tools relevant to working with these file types.

Possible Formats & Ways to Open and Use BDF Files

BDF files were once heavily used in UNIX and Linux systems and now see occasional use in retro or specialized projects. While less popular in comparison to modern font file formats like TTF and OTF, BDF files can still be opened and utilized in various ways, such as:

Font Editors

With font editing software like FontForge, users can open, edit, and convert BDF font files. FontForge is a free, open-source program compatible with Windows, macOS, and Linux systems. By opening a bitmap font file in FontForge, users can make any desired modifications to the font and export the results as a new BDF or different font format.

Programming

BDF files may be integrated into the source code of various programming projects, with libraries available for usage in languages like C and Python. In C programming, UNIX I/O is particularly relevant, while Python users can utilize the bdfparser library for working with BDF files. These libraries can help streamline the process of incorporating BDF files into programs and automate tasks that involve bitmap fonts.

Direct Conversion Tools

Instead of using a font editor, users may prefer a dedicated converter tool like Tufora that can quickly convert a BDF file to other font formats such as TTF and OTF. Such tools generally allow for batch conversion and simple drag-and-drop functionality to streamline the process.

Alternative Uses for the BDF File Extension

Apart from the Bitmap Distribution Format, there are other, less-common applications for BDF file extensions:

BrainVision Electroencephalography (EEG) Data

Some electroencephalography (EEG) recording systems like BrainVision may use the BDF file extension for storing raw EEG data. This information can then be imported into EEG analysis software such as EGI's Geodesic Software Suite or EmotivPRO.

Configuration Files

In some cases, the BDF file extension may appear in backend control configuration files like Gateworks Newport, where it stands for "Board Definition File." These files are specifically used for customizing board configurations for embedded systems.

BDF File Important Information

In summary, the BDF file extension primarily deals with bitmap font files, but it can have alternative uses in the realms of EEG data and embedded system configurations. For those looking to work with BDF font files, resources like FontForge, UNIX I/O for C programming, and bdfparser for Python are valuable tools. However, the BDF file extension is increasingly considered outdated compared to modern font file formats like TTF and OTF. Regardless, understanding how to work with BDF files remains essential for those interested in retro projects or specialized developments.

How Can I Open BDF File on Windows

We researched and learned that the best way to open BDF file is to find a BDF file in question in Windows OS File Explorer and double click on it to launch the corresponding application.
If a BDF file is not opened in an application and you instead get a "Windows can't open a file" error message you should try looking for an application which can open the file in question.

Install the application you found and check if it can open BDF file

How Can I Open BDF File on Mac OS

We recommend to find a BDF file in question in Mac OS Finder and double click on it to launch the corresponding application.
If a BDF file is not opened in a Mac OS application and you instead get a "There is no application set to open the file" error message you can click on "Search App Store" in the error dialog and Mac OS will show you applications compatible with BDF file.
If you know the Mac OS application which can work as BDF file opener you can choose the "Choose Application..." option in the error box to associate the file extension and open BDF file in it.
If you don't know the application which can open BDF file then try to search for "BDF viewer", "application to open BDF file" or "read BDF file" queries in the online search engine you like.
Install the application you found and check if it can read BDF file

How Can I Open BDF File on Android

If you downloaded a BDF file on Android device you can open it by following steps below:

In the Android apps list on your Android device find "My Files" or "File manager" app and tap to start it.
Tap on "Downloads" folder inside the app.
You should see your downloaded BDF file in that folder.
Tap on the file. If Android device supports opening the file you downloaded it will open in the corresponding app.
If file does not open you can look for the corresponding app that can open the file by searching Android App Store for the "BDF".
If you cannot open the file with the apps from Android App Store it is possible that the file could only be opened on desktop platforms such as Windows or Mac OS. Try searching for "BDF viewer", "BDF file reader" online and see if any desktop applications can open it.
It is also possible that the file you downloaded is outdated and is no longer supported.

How to Open BDF File on iPhone or iPad

To open BDF File on iOS device follow steps below:

We advies to open Files app on your iPhone or iPad device. You can find it by swiping down on the home screen and typing "Files" in the search bar.
Tap on the Downloads folder on the Files app home screen.
You will see all files that you recently downloaded. Tap on the BDF file to view it.
If you have the right app that can open it it will automatically launch and open your file.
If you don't have the app which can open it you need to serch Apple app store for "BDF". This way you can find apps which can open BDF files.
If this doesn't help it is possible that your file could be opened only by the desktop application. To find an app which can open it on desktop look for "BDF viewer" or "BDF file" online in your favorite search engine.
