Watermarkd 0.7.2.1

Watermarkd
Friendly Watermarking Software with GUI option.

Watermarkd User Manual
You can find a couple of simple examples below. You are also welcome to visit this tutorial on holypython.com: How to Use Watermarkd: A Batch Watermarking Library with GUI
Installation
Watermarkd can be installed using this command:
pip install watermarkd

or
pip3 install watermarkd

Dependencies
Watermarkd is built on two Python libraries in addition to several default Python libraries. These are:

PIL
PySimpleGui

Please make sure these libraries are installed before using Watermarkd. You can also refer to our requirements.txt.
The Python Imaging Library (PIL) is

Examples
Single File Example
With GUI Enabled
import Watermarkd as wmd

#Enable GUI & Enjoy
wmd.Spread.single(gui=True)


Working Without GUI
import Watermarkd as wmd

#Or work without GUI
wmd.Spread.single(img_path=r"c://Users/ABC/Desktop/Anniversary.jpg")


File will be saved to Desktop under name Watermarkd.png by default.

Batch Example
import Watermarkd as wmd

#Or work without GUI
wmd.Spread.batch(folder_path=r"c://Users/ABC/Desktop/New_Photos")



Files will be saved to Desktop/watermarkd_/ folder by default.

Functions
There are currently two functions in Watermarkd module and they both belong to Spread class. They both aim to do a good job spreading out watermark texts nicely on image file(s).
Spread.single()
single is one of the two current functions, the other being batch. It can be used to watermark a single image file.
It shares most of the same parameters with batch function with the exception of:
-img_path
which is replaced with:
-folder_path
in the batch case.
Default output file name and path are as following:
r"c:/Users/"+user_path+"/Desktop/watermarkd.png"
Spread.batch()
batch the other function can be used to watermark a folder of images at once. This option can be useful for people who has to deal with watermarking images in large amounts and in high frequency.
Currently batch function is missing the GUI component which should be ready soon.
Default output file name and path are as following:
Output Path: r"c:/Users/"+user_path+"/Desktop/watermarkd_/"
Output File: 1.png, 2.png, 3.png, 4.png and so on.
Parameters

gui, (default=False) : Opens graphical user interface when True
img_path: Image's Path and Name for Watermarking
folder_path : For Batch Operation, Folder's Path for Watermarking
wm_text, (default= Watermarkd) : Watermark Text
wm_trans, (default= 85) : Watermark Transparency
font_size, (default= 55) : Watermark Font Size
font_name, (default= "arial.ttf") : Font Type
filename, (default="Watermarkd") : Saving File Name
save_to_path, (default="Desktop/watermarkd_"): Saving Folder Path
save_to_suffix, (default=".png") : Saving File Type
output_filename, (default= r"c:/Users/"+user_path+"/Desktop/watermarkd.png") : Watermarked File Name When Saving Single File

Use Cases
Although watermarking technology existed long before digital technologies (on money, stamps and special documents), its use cases reached astronomical levels with the revolution of digital imaging brought about in the last couple of decades.
Watermarkd aims to help users do watermarking in the most practical sense, without having to open resource heavy Photo Editors. You can probably be done with Watermarking all together via Watermarkd in the time that it takes for a traditional Image Editing Software to load up in most computers.
Through photos, watermarking can be used to:

Communicate contact information
Advertise
Share artist info
Share owner info
Imply Confidentiality
Imply Sensitivity
Post instructions
Notify of copyright
etc.

It's expected to be dominantly used by:

Professional photographers
Illustrators
Visual Artists
Newspapers and Magazines
Bloggers
Media agencies
Businesses in general
Educational institutions
Non-profit organizations
Military & Law Enforcement
Entrepreneurs

Known Issues


Sometimes, current algorithm doesn't spread out the watermark as nicely. This happens in approximately 10-20% of different size and shapes of photos. It can be fixed by improving the algorithm.


In batch function font size is not calculated dynamically. When a folder has images with very different image resolutions this can cause a problem of very different watermark font sizes.

Release Notes
0.7.0.1 - Initial release is out.
0.7.0.2 - Added functionality to add folder for batch operations when saving folder doesn't already exist.
0.7.0.3 - Fixed init.py files for correct installation.
0.7.1.0 - Added Batch GUI, fixed Cancel button, fixed path conflicts
0.7.2.0 - When GUI is closed without picking any image or folder, instead of giving an error, function is terminated by returning None. This should allow repeat operations in a single session and make usage more convenient and smooth for users.

Add color options for watermarking white color dominant images (soon)
Add Dynamic font_size calculation to batch function. (soon)
Improved algorithm For spreading out watermark text (soon)
A sibling class to the only current class: Spread, potentially named Place that can be used to places a single watermark text on the image. (maybe soon)
