Extract text from LaVision DaVis images (IM7)
To convert IM7 images to another format, you need DaVis or other Raster Image software.
To convert other file formats to the "LaVision Scientific Image File" file type, you need software like DaVis or a similar tool.
The .IM7 file is a proprietary scientific image format created by LaVision for its DaVis (Data Acquisition and Visualization) software. These files store raw, high-resolution sensor arrays captured by specialized cameras during complex optical measurements, such as Particle Image Velocimetry (PIV) or Digital Image Correlation (DIC). They natively hold 16-bit integer data, timing information, and multi-frame structures.
To view or analyze these files natively, you need a costly license for LaVision DaVis. In engineering and research environments, users often bypass this requirement by using the ReadIMX add-on for MATLAB or the ReadIM wrapper in Python to load the images directly into code as numerical arrays.
The main disadvantage of the .IM7 format is its highly specialized, closed ecosystem. You cannot open these files in standard web browsers, default operating system viewers, or typical graphic editors. Sharing raw PIV data with clients or non-engineers is a major workflow bottleneck. To make this data usable outside of the laboratory, you must convert .IM7 files to standard image formats.
The best target format is TIFF, which preserves the critical 16-bit intensity depth without data loss. You can also convert them to PNG or JPG for quick viewing or presentations. However, compressing 16-bit scientific data into an 8-bit JPG often causes massive data clipping. If the contrast values are not properly mapped during conversion, the resulting image will look completely black.
Because .IM7 is a closed, proprietary format with non-standard internal headers, generic online converters fail to parse the embedded camera arrays. Often, only the original software or specialized C++ libraries can accurately read the raw matrices. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your IM7 file, detects the exact format, and lets you read the text inside.
Users also converted IM6, IM9, IM1, IMO, IM5, IM4, IM3, IM0, IM2, DICOMDIR and BIN files.
If you want to convert IM7 file to JPG, PDF, PNG, GIF, BMP, TIFF, TIF, WEBP, ICO, CUR, PSD or PSB, you can use DaVis or similar software from the "Scientific Image Storage" category. In the File menu, look for Save As… or Export….
To convert RAW, PNG, AI, NEF, PSB, DNG, SVG, GIF, EPS, JPG, ARW or PDF files to IM7, try DaVis or another comparable tool in the "Scientific Image Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our IM7 converter.
