+# datedStampGenertaor
+A python tool using PIL to generate PNGs of scanned stamps, for multiple dates.
+# Purpose
+This tool's objective is to solve a problem by automating a manual task.
+
+In the context of signing digital documents, a stamp must be applied. This can be done digitally from an image from software such as ABBYY finereader.
+To make this image (PNG with transparency) this is the workflow :
+- Apply the stamp to a piece of paper
+- Scan the paper in high resolution
+- Open the resulting image in Photoshop
+- Mask the background to make it transparent
+- Crop the image to only have the stamp
+- Save as PNG
+
+When then is a dated stamp, whith a changeable date within the stamp impression, it means every date must be converted to a digital PNG individually. This is time consuming.
+
+# What this tool does
+Using PIL, this tool picks from a previously scanned collection of images to combine them into a realistic looking stamp.
+The stamp is separated in parts:
+
+- Outside ring
+- Day
+- Month
+- Year
+
+The tool iterates through every date and generates, then saves the corresponding stamp.
+It picks from different variations of every eement to make a unique stamp each time.
+
+# Weaknesses
+
+This tool generates impossible dates (such as 31 february)
+This tool needs to be supplied with a lot of input data (approx 2h work in photoshop)
+This tool does not use OOP
