NPS Image Editor and Color Picker. Now with layers.
NPS Image Editor is a free multi-layer image editing program for Windows that is perfect for pixel art, drawing, and photo editing. It is lightweight, customizable, and intuitive, yet surprisingly powerful.
NPS Image Editor aims to preserve the simplicity and ease of use of Microsoft Paint for pixel art and screenshot editing while providing an improved set of features, such as the ability to work with transparency, use multiple layers, and apply filters to your image.
NPS Color Picker can be used on its own as a powerful tool for working with colors while designing web pages. It supports multiple color spaces, copying and pasting common color formats, and grabbing a color from any point on your screen (even in other applications).
