GUI Usage


Running vrimg2exr without any parameters, or from the Start menu, will open the GUI version of the tool as seen above. The GUI allows you to convert one or a number of .vrimg files to OpenEXR files. You can also get information about the data stored in a .vrimg file.


Pixel type – Specifies whether the data in the .exr file is saved as 16-bit or 32-bit floating point numbers.

Compression type – Sets the compression type, choosing between the several available methods. If not specified, the ZIP method is used.

  • None
  • RLE - run length encoding
  • ZIPS - one scanline at a time
  • ZIP - in blocks of 16 scanlines
  • PIZ - piz-bazed wavelet compression
  • PXR24 - lossy 24-bit float compression
  • B44 - lossy 4x4 pixel compression, fixed rate
  • B44A - lossy 4x4 pixel compression
  • DWAA - lossy DCT based, blocks of 32 scanlines    
  • DWAB - lossy DCT based, blocs of 256 scanlines       

DWA compression level A floating-point value that controls the compression level when using the lossy DWA compression methods.

Buffer size (in MB) Sets the maximum allocated buffer size. By default, this value is set to 500 MB. If the image does not fit into the max buffer size, it is converted in several passes.

Data window Tries to find the valid data window from the .vrimg file. This requires that the file can be read in one pass. The non-zero pixels in the alpha channel are used to determine the data window.

Available channels Specifies which channels of the .vrimg file are written into the .exr file. Provides a list of all available channels found in the .vrimg file(s) once an input file or directory is selected.

Channels in separate files – When this option is enabled, each channel is written into a separate .exr file.

Multipart output – When this option is enabled, each channel is written into a separate OpenEXR2 'part'.

Input file mode – Selects the input file mode.

  • Single input file – Only a single file is converted. 
  • Multiple input files – Multiple files are converted at once. 

Input file – Specifies the .vrimg file when Single input file is selected as the Input file mode.

Input directory – Specifies the input files' directory when Multiple input files is selected as the Input file mode.

Output directory – Specifies the output directory for the .exr files when Multiple input files is selected as the Input file mode.

Filename – Specifies a search pattern for the input file names. Wildcards (*) are can be used to define the pattern.

Subdirectories – When this option is enabled, all .vrimg files contained in subdirectories of the specified input directory are also converted.

Info – Provides information about the .vrimg file(s) once an input file or directory is selected.

Convert – Starts the conversion.
