This PR fixes an issue where the Sharp `.resize()` function would round
down an auto-scaled dimension when `fastShrinkOnLoad` was enabled
(enabled by default).
This caused slight discrepancies in height calculations in certain edge
cases.
Be default (`fastShrinkOnLoad: true`), Sharp:
- Uses the built-in shrink-on-load feature for JPEG and WebP
- It is an optimization that prioritizes speed over precision when
resizing images
By setting `fastShrinkOnLoad: false`, we force Sharp to:
- Perform a more accurate resize operation instead of relying on quick
pre-shrink methods.
### Before / Context:
- Upload an image with original dimensions of 1500 × 735
- Define an `imageSize` of the following:
```
{
name: 'thumbnail',
width: 300,
},
```
#### Calculation:
`originalAspectRatio = 1500 / 735 ≈ 2.04081632653`
`resizeHeight = 300 / 2.04081632653`
`resizeHeight = 147`
However, Sharp's `.resize()` calculation would output:
`resizeHeight = 146`
This lead to an error of:
```
[17:05:13] ERROR: extract_area: bad extract area
err: {
"type": "Error",
"message": "extract_area: bad extract area",
"stack":
Error: extract_area: bad extract area
}
```
### After:
Sharp's `.resize()` calculation now correctly outputs:
`resizeHeight = 147`
