# ClassifierTypeEnum

ClassifierTypeEnum enumeration constants are used to specify the type of the classifier. The type depends on the document features that the classifier considers when assigning it a category.

```
typedef enum {
  CT_Image    = 0x00000001,
  CT_Text     = 0x00000002,
  CT_Combined = 0x00000004
} ClassifierTypeEnum;
```

| Name           | Description                                                                                                                                                                                                                                                                                     |
| -------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| CT\\\_Combined | The classifier takes into account the characteristics of both the image and the recognized text. The text features can be used only for languages with full dictionary support. See [Predefined Languages in ABBYY FineReader Engine](/fine-reader/engine/specifications/predefined-languages). |
| CT\\\_Image    | The classifier uses only the image features.                                                                                                                                                                                                                                                    |
| CT\\\_Text     | The classifier works with the recognized text. This classifier type can be used only for languages with full dictionary support. See [Predefined Languages in ABBYY FineReader Engine](/fine-reader/engine/specifications/predefined-languages).                                                |
