Can my AI agent convert CUR to CALS?
Yes. Install the Filestar CLI with npm install -g filestar and your agent can run filestarcli -i file.cur -c "convert to cals" on your computer, so your files stay on it.
A CUR file is a cursor image or animation used for the Windows mouse pointer. It may be an arrow (for general use), a spinning hourglass (for waiting periods), or an I-bar (for text editing).
The CALS Raster Graphic File, having the extension .cals, is a type of image file format primarily used for the storage and exchange of digital images, especially in the context of technical and engineering documents. Developed in the mid-1980s by the United States Department of Defense, the CALS format was part of an initiative to standardize electronic document management and interchange, particularly for military and government applications.
