## Class: QPixmap
|
|
|
|
> The QPixmap class helps hold an image in the form of off-screen image representation.
|
|
|
|
**This class is a JS wrapper around Qt's [QPixmap class](https://doc.qt.io/qt-5/qpixmap.html)**
|
|
|
|
A `QPixmap` provides ability to store an image in the memory.
|
|
|
|
**QPixmap inherits from [Component](api/Component.md)**
|
|
|
|
### Example
|
|
|
|
```javascript
|
|
const { QPixmap } = require("@nodegui/nodegui");
|
|
|
|
const imageUrl = "path/to/png";
|
|
const pixMap = new QPixmap(imageUrl);
|
|
```
|
|
|
|
### `new QPixmap(imageUrl?)`
|
|
|
|
- `imageUrl` string (_optional_). Absolute path of the image that needs to be loaded in the memory.
|
|
|
|
### Static Methods
|
|
|
|
QPixmap can access all the static methods defined in [Component](api/Component.md)
|
|
|
|
### Instance Properties
|
|
|
|
QPixmap can access all the instance properties defined in [Component](api/Component.md)
|
|
|
|
### Instance Methods
|
|
|
|
QPixmap can access all the instance methods defined in [Component](api/Component.md)
|
|
|
|
Additionally it also has the following instance methods:
|
|
|
|
#### `pixMap.load(imageUrl)`
|
|
|
|
loads an image from the url into memory as a Pixmap.
|
|
returns true if load was successful otherwise returns false.
|
|
|
|
- `imageUrl` string (_optional_). Absolute path of the image that needs to be loaded in the memory.
|
|
|
|
#### `pixMap.scaled(width, height, aspectRatioMode?)`
|
|
|
|
Scales the pixmap to provided height and width with respect to aspectRatioMode.
|
|
This method doesnt mutate this pixmap and rather returns a new pixmap with new height and width.
|
|
|
|
- `width` number. Width in pixels for new pixmap.
|
|
- `height` number. Height in pixels for new pixmap.
|
|
- `aspectRatioMode` AspectRatioMode (_optional_). Specifies how scaling should happen. [AspectRatio is an enum from Qt](api/QtEnums.md)
