# fsMapViewCreate<no value>
This function can be used to create an initial MapView for later user. Note that there is a limit to how many MapView objects you can create, and you can only have up to **nine** at any one time. Trying to create more than that will cause issues.

 

 

##### Syntax

``` wasm
FsTextureId fsMapViewCreate(
    FsContext ctx,
    unsigned uSizeX,
    unsigned uSizeY,
    FsRenderImageFlags iRenderImageFlags
    )
```

|---------------------|------------------------------------------------------------------------------------------------------------------------------|
| `ctx`               | A value of type `FsContext` provided as an argument of the gauge callback.                                                   |
| `uSizeX`            | Sets the default width. See fsMapViewSetSize for more information.                                                           |
| `uSizeY`            | Sets the default height. See fsMapViewSetSize for more information.                                                          |
| `iRenderImageFlags` | Permits you to use specific render flags to change how the image is rendered. See the [Remarks](#remarks) below for details. |

##### Return Values

Returns the MapView ID which must be used to identify a MapView if further function calls. If the MapView creation fails, the function will return a value &lt;0.

 

##### Remarks

When using this function you can set 1 or more render flags for the `iRenderImageFlags` parameter. These can be bitwise OR'd together to create a bitmask that will be used when rendering, for example:

``` wasm
FS_RENDER_IMAGE_REPEATX | FS_RENDER_IMAGE_FLIPY
```

The available flags are as follows:

| Flags                           | Description                                                                                                                                               |
|---------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------|
| `FS_RENDER_IMAGE_REPEATX`       | The image should be repeated along the X axis.                                                                                                            |
| `FS_RENDER_IMAGE_REPEATY`       | The image should be repeated along the Y axis.                                                                                                            |
| `FS_RENDER_IMAGE_FLIPY`         | The image should be flipped along the Y axis.                                                                                                             |
| `FS_RENDER_IMAGE_PREMULTIPLIED` | The image should be considered as having pre-multiplied alpha.                                                                                            |
| `FS_RENDER_IMAGE_NEAREST`       | The image should be rendered using "nearest neighbour" interpolation instead of the default bilinear interpolation (thus giving a more pixelated effect). |
