The STM file type is primarily associated with PhotoStudio, a photo editing software developed by ArcSoft. It specifically refers to the PhotoStudio Stamp file, which is used to store stamp data or templates that can be applied to images within the software. These stamp files allow users to easily add pre-designed graphical elements, such as symbols, icons, or decorative motifs, to their photographs or projects. The STM format facilitates the customization and enhancement of images by providing a library of creative assets directly within the PhotoStudio environment.
It is an icon image file used to show application icons in the macOS Finder and macOS dock. It contains one or several .PNG images and it supports 1bit and 8-bit alpha channels.
