Convert FIG to RLA

Understanding FIG and RLA file formats

FIG files are vector graphics files created by the Xfig drawing program, commonly used on Unix systems. They store graphical objects such as lines, shapes, and text in a text-based format, making them ideal for technical diagrams and illustrations.

RLA (Run-Length Encoded Image) files are raster image files developed by Wavefront Technologies. RLA files are primarily used in 3D rendering and visual effects workflows, storing high-quality images with support for multiple channels, including alpha and depth information.

How to convert FIG to RLA

Converting a FIG vector file to a RLA raster image is a two-step process, as there is no direct converter. First, you need to export the FIG file to a common raster format (such as PNG or TIFF), then convert that raster image to RLA.

Step 1: Export FIG to a raster format

Use Xfig or fig2dev to export your FIG file:

• Open your file in Xfig.
• Go to File → Export.
• Select a raster format like PNG or TIFF.
• Save the exported file.

Alternatively, use the command line tool fig2dev:

fig2dev -L png input.fig output.png

Step 2: Convert raster image to RLA

Once you have a PNG or TIFF, use Adobe Photoshop (with the RLA plugin) or FFmpeg (if compiled with RLA support) to convert the raster image to RLA:

• In Photoshop, open the PNG/TIFF file.
• Go to File → Save As and choose RLA as the format.

Alternatively, use FFmpeg:

ffmpeg -i input.png output.rla

Note: RLA support in FFmpeg may require specific builds or plugins.

Recommended software for FIG to RLA conversion

• Xfig and fig2dev for exporting FIG to raster formats.
• Adobe Photoshop (with RLA plugin) for converting raster images to RLA.
• FFmpeg for command-line conversion if RLA support is available.

There are no direct online converters for FIG to RLA, so using these tools is the most reliable method.
