PhotoDemon 是一个Windows平台上的免费、免安装、开源的图像编辑软件。

    官方版本支持且只有免安装版，大小只有12.5mb。看了看常见的图片处理功能都支持，完美解决我的多层需求，而且支持中文版。体积小、支持多层、免安装这些亮点很不错。

    Its design is guided by three principles:

    Portability Portability

    PhotoDemon does not require installation, administrator rights, or Internet access. Its tiny footprint allows it to run directly from USB devices.

    Power Power

    The current build provides more than 200 professional-grade tools, including digital darkroom essentials like shadow/highlight recovery, multi-channel curves, content-aware resizing, and full support for Adobe Photoshop (PSD) files.

    Usability Usability

    An elegant interface built by designers - not engineers - gets out of the way and lets you work. Usability testing drives our design decisions.
