Extract text from Pattern files (PATTERN)
To convert PATTERN patterns to another format, you need Systems Tool Kit or other Data software.
To convert other file formats to the "Application Specific Data" file type, you need software like Systems Tool Kit or a similar tool.
The .PATTERN file extension primarily identifies two distinct types of proprietary data: a custom sensor pattern used by Systems Tool Kit (STK) (developed by AGI/Ansys) to model spatial sensor orientations, or a graphic tiling file used by the PhotoLine image editing software. In niche scientific scenarios, it is also used by the Bio-Formats library as a text-based grouping file to stitch together multiple microscopy images into a single dataset.
This format creates a significant bottleneck for users. An STK sensor pattern is loaded with proprietary, STK-specific parameters (like complex AzElMask data) that standard 3D or GIS platforms simply cannot read. Similarly, PhotoLine patterns are closed binary files. If you do not own a license for the exact parent software, these files are completely inaccessible. You cannot open them in a web browser, and standard image viewers or text editors will often just throw a generic error.
To make this data usable, conversion is mandatory. For STK data, converting the raw output to CSV or JSON is highly recommended, as it allows you to analyze the sensor math in Excel or Python, though the native 3D visualization will be lost. For PhotoLine graphics, you should aim to extract the visual data into standard PNG or JPG formats so you can recreate the pattern in mainstream software like Adobe Photoshop.
Unfortunately, generic online converters fail with .pattern files because they lack the specific parsing logic to tell a 3D sensor file apart from a bitmap graphic. The proprietary nature of the encoding means only the original software can natively export the data perfectly. Our analyzer will inspect the file's binary signature, reveal any underlying plain-text STK arrays, or extract the embedded visual content if it matches known graphic protocols.
Convert.Guru analyzes your PATTERN file, detects the exact format, and lets you read the text inside.
Users also converted PAT, PNG, AVIF, JPG, WEBP, PDF and ZIP files.
If you want to convert PATTERN file to JPG, PDF, PNG, GIF, BMP, TIFF, TIF, WEBP, ICO, CUR, PSD or PSB, you can use Systems Tool Kit or similar software from the "Sensor & Graphical Pattern Data" 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 PATTERN, try Systems Tool Kit or another comparable tool in the "Sensor & Graphical Pattern Data" 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 PATTERN converter.
