|
|
+### getDefaultConfig
|
|
|
+
|
|
|
+When you use the `ComPDFKit.openDocument` method to present a PDF file, you need to pass configuration parameters to customize the UI features and PDF view properties. `ComPDFKit` provides default configuration parameters through `ComPDFKit.getDefaultConfig`. You can retrieve them using the following example:
|
|
|
+
|
|
|
+```tsx
|
|
|
+ComPDFKit.getDefaultConfig({})
|
|
|
+```
|
|
|
+
|
|
|
+You can modify certain parameters to meet your requirements. Here are some usage examples:
|
|
|
+
|
|
|
+1. Setting the initial display mode and available mode list. The following code is an example that enables only the viewer mode and annotation mode:
|
|
|
+
|
|
|
+```tsx
|
|
|
+ComPDFKit.getDefaultConfig({
|
|
|
+ modeConfig: {
|
|
|
+ initialViewMode: CPDFViewMode.VIEWER,
|
|
|
+ availableViewModes: [
|
|
|
+ CPDFViewMode.VIEWER,
|
|
|
+ CPDFViewMode.ANNOTATIONS
|
|
|
+ ]
|
|
|
+ }
|
|
|
+})
|
|
|
+```
|
|
|
+
|
|
|
+2. Setting the enabled annotation types and the default annotation attribute values list. For example, enabling only note annotations and setting the color and transparency of note annotations:
|
|
|
+
|
|
|
+```tsx
|
|
|
+ComPDFKit.getDefaultConfig({
|
|
|
+ annotationsConfig:{
|
|
|
+ availableType:[
|
|
|
+ CPDFAnnotationType.NOTE
|
|
|
+ ],
|
|
|
+ availableTools:[
|
|
|
+ CPDFConfigTool.SETTING,
|
|
|
+ CPDFConfigTool.UNDO,
|
|
|
+ CPDFConfigTool.REDO
|
|
|
+ ],
|
|
|
+ initAttribute:{
|
|
|
+ note:{
|
|
|
+ color: '#1460F3',
|
|
|
+ alpha: 255
|
|
|
+ }
|
|
|
+ }
|
|
|
+ }
|
|
|
+})
|
|
|
+```
|
|
|
+
|
|
|
+3.Setting the display mode and page turning direction:
|
|
|
+
|
|
|
+```tsx
|
|
|
+ComPDFKit.getDefaultConfig({
|
|
|
+ readerViewConfig:{
|
|
|
+ displayMode: CPDFDisplayMode.DOUBLE_PAGE,
|
|
|
+ verticalMode: false
|
|
|
+ }
|
|
|
+})
|
|
|
+```
|
|
|
+
