![]() ![]() Plus, you can apply various filters like Gaussian blur, unsharp mask and variance, use batch tools for measurements, conversion, macro or virtual stack, subtract the background, analyze particles, view a histogram, capture the screen, and many others. Plus, you can fill or draw within a selection, create a mask, as well as rotate or enlarge the image.įurthermore, you can configure options when it comes to the line width, fonts, arrow, hand or point tool, colors, appearance, and others.Īdditionally, you can adjust the brightness, contrast and color balance, merge or split channels, add a slice, create a new hyperstack, zoom in and out, as well as crop, duplicate, rename or scale the image. So, you can open samples and import image sequences, animated GIFs and others. You can import images by using the file browser or the "drag and drop" method. It supports several formats, including JPEG, BMP, GIF and TIFF. ImageJ is a Java-based program that allows you to edit image files.
