BMP Image Editor

BMP Image Editor is a small and portable application that enables you to view, edit and analyze BMP images. Although it comes packed with just a few options, most of them are advanced, primarily catering to experienced users.

Since installation is not a requirement, you can drop the program files to any location on the hard disk and just click the executable file to run (found in Bin -> Debug directory).

It is also possible to save BMP Image Editor to a USB flash disk or similar storage unit, to be able to run it on any machine effortlessly, without previous installers.

What's more, the app does not create new registry entries or additional files on the HDD without the user's approval.

The interface is made from a standard window with a clean aspect, where you can open a BMP file using the file browser only, since drag-and-drop is not supported. It is possible to tweak the image using an average or median filter, equalize the histogram, convert the picture to binary mode, as well as to invert colors.

You can view the histogram and file properties (e.g. size, offset to bitmap data, total colors, horizontal and vertical resolution), along with detected lines and extra information (mean, variance, moment, central moment). Although it is not possible to undo actions one step at a time, you can revert the picture to its original state. Changes can be overwritten to file or saved to a new one.

BMP Image Editor uses low-to-moderate RAM and low CPU, so it does not hog system resources. However, the app popped up several errors and crashed during our evaluation. It seems to have compatibility issues with Windows 7 64-bit.
