Manual Cropping in Images via Free Python API

Using Thumbor API you can the functionality of cropping images manually in your own applications. In order to perform manual cropping, you need to pass two points as arguments separated by a colon. where the first point is the left-top point of the cropping rectangle and the second point is the right-bottom point. This crop is performed before the rest of the operations, so it can be used as a preparation step before resizing and smart-cropping

Smart Cropping via Python API


$thumbor
    ->url($url)
    ->smartCrop(true)
    ->resize(150,400);

Horizontal and Vertical Image Alignment - Python

The Open Source image library thumbor allows aligning images horizontally and vertically. The horizontally align image controls where the crop of the image will occur. You can use three parameters for the horizontal align feature. Left only the left side, the center will trim equally from both sides, and the right will only trim from the right. Similarly, while using verticle alignment, the top only trims the bottom, the center will trim from both top and bottom, and the bottom align will trim the image from the top.

Add Filters in Images via Free Python API

Thumbor allows python developers to add filters in images programmatically. The API runs the filters in a pipeline and each filter is applied to the image in a specified order. The API provides a wide range of filters including, AutoJPG, Background Color, Blur, Brightness, Contrast, Convolution, Equalize, Extract focal points, Filling, Focal, Format, greyscale, Maxbytes, No upscale, Noise, Proportion, Quality, Red eye, RGB, Rotate, Round Corners, Sharpen, Stretch, Strip EXIF, Strip ICC, and watermark.

Apply Stretch Filters via Python

from preggy import expect

from tests.base import FilterTestCase


class StretchFilterTestCase(FilterTestCase):
    def test_stretch_filter(self):
        self.get_filtered('source.jpg', 'thumbor.filters.stretch', 'stretch()')
        expect(self.context.request.stretch).to_be_true()
