# Image

Mit der Image-Component lassen sich Bilder in der Benutzeroberfläche einbinden.

## Overview

# Playground

In `<Image />` wird über die Property `src` die Bildquelle festgelegt. Mithilfe
weiterer Properties wie `width` und `height` lässt sich dessen Größe individuell
anpassen.

```tsx
import { Image } from "@mittwald/flow-react-components";

<Image
  src="https://flow.mittwald.de/assets/mittwald_logo_rgb.jpg"
  alt="mittwald"
  width={200}
/>
```

---

# Responsive Images

Um Bilder in unterschiedlichen Auflösungen für verschiedene Bildschirmgrößen
bereitzustellen, eignet sich das `srcSet`-Attribut. Damit lassen sich mehrere
Varianten einer Bilddatei hinterlegen – sowohl in niedriger als auch in hoher
Auflösung –, die je nach Pixeldichte des Endgeräts automatisch ausgewählt
werden. Weitere Informationen dazu finden sich im folgenden Artikel:
[Responsive Images](https://developer.mozilla.org/en-US/docs/Learn/HTML/Multimedia_and_embedding/Responsive_images#resolution_switching_same_size_different_resolutions:~:text=Resolution%20switching%3A%20Same%20size%2C%20different%20resolutions).

---

# Border

Mit der Property `withBorder` erhält die Image-Component eine Border. Dieser ist
insbesondere bei Bildern mit geringem Kontrast zum Hintergrund von Vorteil, da
er die visuelle Abgrenzung verbessert und die Bildwahrnehmung unterstützt.

```tsx
import { Image } from "@mittwald/flow-react-components";

<Image
  src="https://flow.mittwald.de/assets/mittwald_logo_rgb.jpg"
  alt="mittwald"
  width={200}
  withBorder
/>
```

---

# Fixes Seitenverhältnis

Die Property `aspectRatio` definiert das Seitenverhältnis der Image-Component.
Weicht das Seitenverhältnis des eingebetteten Bildes ab – etwa durch eine
größere Höhe oder Breite –, wird das Bild zentriert, und überstehende Bereiche
außerhalb des festgelegten Verhältnisses werden ausgeblendet.

```tsx
import { Image } from "@mittwald/flow-react-components";

<Image
  src="https://flow.mittwald.de/assets/mittwald_logo_rgb.jpg"
  alt="mittwald"
  width={200}
  aspectRatio={16 / 9}
  withBorder
/>
```

## Best practices

Achte bei der Verwendung der Image-Component darauf, dass ...

- die eingebundenen Bilder die Benutzeroberfläche sinnvoll ergänzen, indem sie
  zum Kontext und der allgemeinen Gestaltung passen.
- Inhalt oder Zweck des Bildes mittels aussagekräftigem `alt`-Text beschrieben
  wird. Rein dekorative Bilder bekommen ein leeres `alt`-Attribut (`alt=""`).
- die Größenverhältnisse optimiert sind, um Ladezeiten und Performance zu
  verbessern.
- Auflösung und Seitenverhältnis der gewählten Bilder angenehm und konsistent
  sind.
- bei mangelndem Kontrast zum Hintergrund die Image-Component eine sichtbare
  Border erhält.
- nach Möglichkeit kein Text im Bild verwendet wird, da dieser von Screenreadern
  nicht erfasst werden kann.

## Verwendung

Verwende die Image-Component, um ...

- dekorative Bilder anzuzeigen, die die Benutzeroberfläche visuell aufwerten und
  positive Emotionen bei den Usern auslösen können.
- hilfreiche Bilder anzuzeigen, die den Kontext so unterstützen, dass Inhalte
  schneller erfasst und besser verstanden werden.
