### `showRenderError` [#showrendererror]

<ApiSignature>

@property (nonatomic, assign) BOOL showRenderError;

</ApiSignature>

```text
是否显示 Slide 中的错误提示

 - `YES`：显示。
 - `NO`：不显示 (默认)。
```

Declared in SDK/WhiteSlideAppParams.h

<a id="//api/name/debug"></a>

### `debug` [#debug]

<ApiSignature>

@property (nonatomic, assign) BOOL debug;

</ApiSignature>

```text
是否开启 Debug 模式 (默认 NO)。
```

Declared in SDK/WhiteSlideAppParams.h

<a id="//api/name/enableGlobalClick"></a>

### `enableGlobalClick` [#enableglobalclick]

<ApiSignature>

@property (nonatomic, assign) BOOL enableGlobalClick;

</ApiSignature>

```text
是否可以通过点击 ppt 画面执行下一步功能 (默认 YES)。
```

Declared in SDK/WhiteSlideAppParams.h

<a id="//api/name/minFPS"></a>

### `minFPS` [#minfps]

<ApiSignature>

@property (nonatomic, strong, nullable) NSNumber *minFPS;

</ApiSignature>

```text
设置最小 fps, 应用会尽量保证实际 fps 高于此值, 此值越小, cpu 开销越小。未设置时由内嵌 Bridge 根据 WebView UA 决定。
```

Declared in SDK/WhiteSlideAppParams.h

<a id="//api/name/maxFPS"></a>

### `maxFPS` [#maxfps]

<ApiSignature>

@property (nonatomic, strong, nullable) NSNumber *maxFPS;

</ApiSignature>

```text
设置最大 fps, 应用会保证实际 fps 低于此值, 此值越小, cpu 开销越小。未设置时由内嵌 Bridge 根据 WebView UA 决定。
```

Declared in SDK/WhiteSlideAppParams.h

<a id="//api/name/resolution"></a>

### `resolution` [#resolution]

<ApiSignature>

@property (nonatomic, strong, nullable) NSNumber *resolution;

</ApiSignature>

```text
渲染分辨倍率, 原始 ppt 有自己的像素尺寸，当在 2k 或者 4k 屏幕下，如果按原始 ppt 分辨率显示，画面会比较模糊。可以调整此值，使画面更清晰，同时性能开销也变高。
 未设置时由内嵌 Bridge 根据 WebView UA 决定。
```

Declared in SDK/WhiteSlideAppParams.h

<a id="//api/name/maxResolutionLevel"></a>

### `maxResolutionLevel` [#maxresolutionlevel]

<ApiSignature>

@property (nonatomic, strong, nullable) NSNumber *maxResolutionLevel;

</ApiSignature>

```text
Used to set the maximum display resolution. This value not only affects the canvas rendering resolution, but also affects the texture quality.
 On low-end devices, reducing this value can greatly improve memory usage and image black screen phenomenon.

 [0] 640 * 360

 [1] 960 * 540;

 [2] Normal 1280 * 720; --- default setting for mobile devices.

 [3] HD 1920 * 1080;

 [4] 3K 3200 × 1800, greater than 4 is calculated as 4; --- default setting for PC devices.

 If unset, the embedded Bridge chooses a value based on the WebView user agent.
```

Declared in SDK/WhiteSlideAppParams.h

<a id="//api/name/forceCanvas"></a>

### `forceCanvas` [#forcecanvas]

<ApiSignature>

@property (nonatomic, assign) BOOL forceCanvas;

</ApiSignature>

Whether to force the use of 2D rendering, forcing the use of 2D rendering will lose some 3D, filters, and effects. (默认 NO)。
```

Declared in SDK/WhiteSlideAppParams.h

<a id="//api/name/bgColor"></a>

### `bgColor` [#bgcolor]

<ApiSignature>

@property (nonatomic, copy, nullable) NSString *bgColor;

### `invisibleBehavior` [#invisiblebehavior]

<ApiSignature>

@property (nonatomic, copy, nullable) PPTInvisibleBehaviorKey invisibleBehavior;

</ApiSignature>

```text
Specify the behavior after hiding the slide; Freeze will destroy the slide and replace it with a snapshot, while Pause simply pauses the slide @default: 'frozen'
```

Declared in SDK/WhiteSlideAppParams.h

<a id="//api/name/resourceMaxRetries"></a>

### `resourceMaxRetries` [#resourcemaxretries]

<ApiSignature>

@property (nonatomic, strong) NSNumber *resourceMaxRetries;

</ApiSignature>

```text
设置 Slide 资源加载最大重试次数 (默认 3)。
```

Declared in SDK/WhiteSlideAppParams.h

</ApiSignature>

fifo（默认）或 latest-pending-render；后者仅合并待执行的渲染页，不中断正在执行的任务。

```text
Slide 同步事件队列策略。`fifo` 按顺序处理全部事件；`latest-pending-render` 允许交互模式跳过积压的中间页面渲染。未设置时由 Slide 使用 `fifo`。
```
