|---|---|
| CompareDocumentsToImages(const System::SharedPtr<Document>&, const System::SharedPtr<Document>&, const System::String&, const System::String&, const System::SharedPtr<System::Drawing::Imaging::ImageFormat>&) | Compares documents graphically. The comparison result is placed in images. |
| CompareDocumentsToPdf(const System::SharedPtr<Document>&, const System::SharedPtr<Document>&, const System::String&) | Compares documents graphically. The comparison result is placed in a PDF document. |
| ComparePagesToImage(const System::SharedPtr<Page>&, const System::SharedPtr<Page>&, const System::String&) | Compares pages graphically. The comparison result is placed in a image. |
| ComparePagesToPdf(const System::SharedPtr<Page>&, const System::SharedPtr<Page>&, const System::String&) | Compares pages graphically. The comparison result is placed in a PDF document. |
| ComparePagesToPdf(const System::SharedPtr<Page>&, const System::SharedPtr<Page>&, const System::SharedPtr<Document>&) | Compares pages graphically. The comparison result is placed in a PDF document. |
| get_Color() const | Gets and sets the change flag color. The default color is red. |
| get_Resolution() const | Gets and sets the resolution of the resulting images. The default value is 150dpi. |
| get_Threshold() const | Gets and sets the threshold value in percentage. This value allows you to ignore small changes if they are not significant to you. The default value is 0%. |
| GetDifference(const System::SharedPtr<Page>&, const System::SharedPtr<Page>&) | Gets differences between pages images. The result contains an image of the first page compared and an array of differences. |
| GraphicalPdfComparer() | Creates an instance of GraphicalPdfComparer class. |
| set_Color(const System::SharedPtr<Aspose::Pdf::Color>&) | Gets and sets the change flag color. The default color is red. |
| set_Resolution(const System::SharedPtr<Aspose::Pdf::Devices::Resolution>&) | Gets and sets the resolution of the resulting images. The default value is 150dpi. |
| set_Threshold(double) | Gets and sets the threshold value in percentage. This value allows you to ignore small changes if they are not significant to you. The default value is 0%. |
