Convert TIFF to GEM

Understanding TIFF and GEM file formats

TIFF (Tagged Image File Format) is a widely used raster image format known for its high quality and support for lossless compression. It is commonly used in photography, publishing, and scanning due to its ability to store detailed image data and multiple layers.

GEM (Graphics Environment Manager) file format is a vector graphics format developed for the GEM desktop environment, popular in the 1980s on Atari ST computers. GEM files are primarily used for storing vector-based images, such as diagrams and illustrations, rather than raster images.

Why convert TIFF to GEM?

Converting a TIFF image to a GEM file is useful when you need to use raster images in legacy GEM-based applications or on Atari ST systems. Since GEM is a vector format, the conversion process typically involves raster-to-vector conversion, which may not preserve all image details.

How to convert TIFF to GEM

Direct conversion from TIFF to GEM is not commonly supported by mainstream image editors. The process usually involves two steps:

1. Convert the TIFF image to a common vector format (such as SVG or WMF) using a raster-to-vector converter.
2. Convert the vector file to GEM format using specialized software.

Recommended software for TIFF to GEM conversion

• Inkscape: Open-source vector graphics editor that can import TIFF files and export to SVG or WMF. Use File → Open to import TIFF, then File → Save As to export as SVG or WMF.
• GEM-View: A legacy tool for Atari ST emulators that can open and save GEM files. After converting your image to a compatible vector format, use GEM-View to import and save as GEM.
• Online Convertors: Some online tools may offer raster-to-vector conversion, but GEM support is rare. You may need to use a two-step process as described above.

Conversion steps summary

1. Open your TIFF file in Inkscape.
2. Trace the bitmap to convert it to vector (use Path → Trace Bitmap).
3. Save the traced image as SVG or WMF.
4. Open the SVG or WMF file in GEM-View or a compatible Atari ST emulator tool.
5. Export or save the file as GEM format.

Tips for best results

• Since GEM is a vector format, simple images with clear lines convert better than complex photographs.
• Manual editing after tracing may be required to optimize the vector image before saving as GEM.
• Always keep a backup of your original TIFF file in case you need to adjust conversion settings.
