image-merger

`

A small Python library to merge images easily

Installation

pip install image-merger

Usage

Simple use case

from ImageMerger import Merger, ImageToMerge, MERGE_GRID

# Initialize list of images
list_images = [
	ImageToMerge(path='images/samples/1.png'),
	ImageToMerge(path='images/samples/2.png'),
	ImageToMerge(path='images/samples/3.png'),
	ImageToMerge(path='images/samples/4.png')
]

# Load merger with different settings
m = Merger(list_images=list_images)

# Save merged image
m.save_image(filename="images/results/output_4_grid.png")

Parameters

• limit_horizontal: int: Optional int to define the maximum number of images to append horizontally
• limit_vertical: int: Optional int to define the maximum number of images to append vertically
• suffle: bool: Optional boolean to decide if list_images must be shuffled prior to process. Default False
• merge_strategy: int: Optional int to set the merging strategy. Either MERGE_HORIZONTALLY, - MERGE_VERTICALLY or MERGE_GRID(default)
• preserve_aspect_ratio: bool: Optional boolean that defines if proportion of each image should be kept or if image can be squeezed/extended to fit. Default False
  • Setting it to True can lead to images being distored to fit layout but there will be no gaps.
  • Setting it to False will kept each image aspect ratio but can lead to black gaps in output image.

Configuration examples

• ImageToMerge.path can either be a path(local or relative) or HTTP(S) URL
• limit_horizontal and limit_vertical are optional and can also be used at the same time
• If limit_horizontal and limit_vertical are not set, and merge_strategy is set to MERGE_GRID The process will try to fit as best as possible all images in a square grid.
• List of images can be shuffled randomly using shuffle=True parameter
