Area Calculator

Area Calculator is an application that you can use to calculate the area of a leaf in graphic files, which must be previously processed with a flatbed scanner and photo processing tool.
It offers support for BMP format only. The tool doesn't feature complicated options or configuration parameters, so it can be handled with ease by all types of users. However, you must have .NET Framework installed before using this app.

Simple GUI for calculating BMP leaf areas

After a simple setup operation which requires minimal user assistance, you can check out the main window with a plain appearance, yet user-friendly structure, inviting you to open a BMP image with the help of a file browser.
The photo can be previewed in this panel. The program makes all the necessary calculations automatically, revealing the image width, height and total pixels, non-white and total pixels, along with the width and height resolution (px/inch), size (mm) and total area.
When it comes to the leaf area, you can check out the subject percentage and calculated subject percentage (sq mm and cm). As far as other options are concerned, you can find out the actual default path, set the current image's folder as the default path, as well as run the bitmap with the click of a button. There are no other notable settings provided by this piece of software.
