Patrik 9d6583d9de fix: incorrect height rounding when resizing images with sharp (#11634)
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`

  • Build faster, never hit a roadblock

Quickstart

Before beginning to work with Payload, make sure you have all of the required software.

pnpx create-payload-app@latest

If you're new to Payload, you should start with the website template (pnpx create-payload-app@latest -t website). It shows how to do everything - including custom Rich Text blocks, on-demand revalidation, live preview, and more. It comes with a frontend built with Tailwind all in one /app folder.

One-click templates

Jumpstart your next project by starting with a pre-made template. These are production-ready, end-to-end solutions designed to get you to market as fast as possible.

🌐 Website

Build any kind of website, blog, or portfolio from small to enterprise. Comes with a fully functional front-end built with RSCs and Tailwind.

We're constantly adding more templates to our Templates Directory. If you maintain your own template, consider adding the payload-template topic to your GitHub repository for others to find.

🔌 Plugins

Payload is highly extensible and allows you to install or distribute plugins that add or remove functionality. There are both officially-supported and community-supported plugins available. If you maintain your own plugin, consider adding the payload-plugin topic to your GitHub repository for others to find.
