The HDP file extension is a raster image format associated with the Microsoft HD Photo image codec. It is a lossless image compression format specifically designed to work with high-definition digital photos. The quality of images within an HDP file is retained more accurately than comparably sized JPEG image files, making it an ideal format for archiving photographic images. HDP files are often used in .TIFF type applications, allowing more detailed images to be stored at reasonable file sizes.
Functionality and Technical Details
Technically, the HDP file format uses a combination of wavelet-based compression algorithm called HomePortable Network Format (HNF) and the bit equalizing algorithm named HUFF (HNF Universal Function Form). Together, these two algorithms provide high-effectiveness in compression of photographic images. An HDP file supports up to three channels – red, green and blue – and is capable of handling 16-bits-per-channel color depth. By comparison with other lossless compression formats like .PNG, .GIF, and .TIFF, HDP is able to provide superior compression and color accuracy while producing significantly smaller files.
Applications and Software
HDP files can be opened in a variety of image programs, including photo editing applications such as Adobe Photoshop, Corel PHOTO-PAINT, as well as document viewers such as Microsoft Office Visio, Adobe Acrobat Reader, and other applications like ACDSee Picture Viewer. It is also supported by many web browsers, so it can be used for displaying images on webpages. The conversion from HDP to other compressed formats or vice versa can be done with the majority of image processing software that supports the mentioned file types, such as PNG, GIF, TGA, BMP, JPG, etc.
Programs for WINDOWS system
Programs for MAC system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .HDP) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .HDP extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .HDP file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .HDP extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .HDP extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .HDP file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .HDP file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .HDP file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .HDP file) will be extended to the maximum.
It is also good to check
- if the .HDP file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
