There are edge cases where Image::resize() with the aspect ratio constraint generates for the same image and nearly
identical width/height parameters different results although one would expect identical images.
For example, if you downsize (with aspect ratio constraint) a landscape image (width > height) and you pass $width/$height
parameters to Image::resize() where $width < $height is true, you would expect that you always get the same output image
regardless of the value of $height, because in that case the $width is the limiting dimension.
This script generates three output images for the same input image with different $width and $height input parameters.
It is expected that all three images are exactly the same size. As outlined below assets/output3.jpg will have an unexpected
height.
| Filename | Input parameters $w x $h |
Expected output dimension | Actual output Dimension |
|---|---|---|---|
| output1.jpg | 100xNULL | 100x67 px | 100x67 px |
| output2.jpg | 100x130 | 100x67 px | 100x67 px |
| output3.jpg | 100x131 | 100x67 px | 100x66 px |
