Creating images
Creating images for testing can be a challenging task. The goal of this library is to help you out with basic tasks. You can easily generate very basic graphic images (no custom shapes).
If you don’t like how image files are generated by this library, you can check the faker-file package, which can produce complex images.
Supported image formats
Currently, 7 image formats are supported:
PNGSVGBMPGIFTIFPPMJPG
Generating images as bytes
See the following fully functional snippet for generating a PNG image.
from fake import FAKER
png_bytes = FAKER.png()
See the full example
here
The generated PNG image will be an image filled with a given colour of a
size 100x100 px.
If you want an image of a different size or colour, provide size
(width, height: Tuple[int, int])
or color (RGB tuple: Tuple[int, int, int]) arguments.
See the example below:
png_bytes = FAKER.png(size=(500, 500), color=(127, 127, 127))
See the full example
here
Generating files
Generate a PNG image.
png_file = FAKER.png_file()
See the full example
here
With size and color tweaks:
png_file = FAKER.png_file(size=(500, 500), color=(127, 127, 127))
See the full example
here
All other image formats (SVG, BMP, GIF, TIF, PPM and
JPG) work in exactly the same way.
The only format that slightly deviates from others is JPG. Produced
JPG images are still rectangles, but unlike all others, instead of being
filled with a single solid colour, they are filled with a mixture of colours,
based on a chosen base colour. Also, colours on the JPG image are not
precise, but a closest match to the colour given.
The following code will generate a 10x10 px square filled with a solid yellow colour.
from fake import FAKER
FAKER.jpg_file(size=(10, 10), color=(182, 232, 90))
While the following code will generate a 640x480 px square filled with yellow and other colours.
from fake import FAKER
FAKER.jpg_file(size=(640, 480), color=(18, 52, 185))
The only colour that always stays solid is the default colour - gray
(128, 128, 128).
from fake import FAKER
FAKER.jpg_file(size=(720, 540))
