Convert CMP to ANX

Understanding CMP and ANX file formats

CMP files are typically associated with compressed image formats, most notably the LEAD Technologies Compressed Bitmap format. These files are used to store bitmap images in a compressed form, often for use in specialized imaging applications.

ANX files, on the other hand, are most commonly known as Analysis Exchange Files used by ArcGIS software, or as HotDocs Answer Files. However, in the context of image or multimedia conversion, ANX can also refer to Annodex files, which are used for time-continuous data such as audio and video streams, based on the Ogg container format.

How to convert CMP to ANX

Direct conversion from CMP (compressed bitmap) to ANX (Annodex multimedia) is not commonly supported by mainstream converters, as these formats serve different purposes. To achieve this conversion, you typically need to:

1. First, decompress the CMP file to a standard image format such as BMP or PNG.
2. Then, encode the image into a video or multimedia stream and save it as an ANX (Annodex) file.

Recommended software for conversion

For the CMP to standard image step, use LEADTOOLS or XnView:

• Open the CMP file in XnView.
• Go to File → Save As and choose BMP or PNG.

For the image to ANX step, use ffmpeg2theora with Annodex support or the Annodex tools:

• Convert the image to a video stream using ffmpeg: ffmpeg -loop 1 -i image.png -c:v theora -t 10 output.ogv
• Use Annodex tools to wrap the Ogg video into an ANX file: oggz-merge --anx output.ogv > output.anx

Summary

While there is no direct one-step converter from CMP to ANX, the process involves decompressing the CMP image and then encoding it into an Annodex multimedia file. XnView and Annodex tools are the best software choices for this workflow.
