and there is a picture of test.jpg in the root directory of the nginx website
via access
http://127.0.0.1/test.jpg!c300x200.jpg will generate/output a 300×200 thumbnail of test.jpg
where c is the parameter for generating image thumbnails and 300 is The width 200 of the generated thumbnail is the height of the generated thumbnail
A total of four different types of thumbnails can be generated.
Support jpeg / png / gif (Gif is turned into a static picture after it is generated)
The C parameter starts at 10% of the height of the picture according to the requested aspect ratio to intercept the picture, and then zoom/zoom in To the specified size (the size of the image thumbnail is equal to the requested width and height)
The M parameter centers the screenshot image according to the requested aspect ratio, and then zooms/enlarges to the specified size (the size of the image thumbnail is equal to the requested width and height)
The T parameter is scaled/zoomed in proportion to the specified size according to the requested aspect ratio (the size of the image thumbnail may be smaller than the requested width and height)
The W parameter is scaled according to the requested aspect ratio/ Zoom in to the specified size, fill the blank with a white background color (the size of the image thumbnail is equal to the requested width and height)
