| virtual bool16 IImageWriteFormatInfo::CanWriteAll | ( | IImageAttributes * | iImageAttributes | ) | |
| pure virtual |
Returns kTrue if the filter can write every attribute in the image, else kFalse.
Note: If a filter returns kFalse but the caller still uses it to create an image, then those tags that are not supported will be dropped by the filter.
- Parameters
| iImageAttributes | IN The attributes to use for the write |
- Returns
- kTrue if every attribute in the image can be written, else kFalse
| virtual OSType IImageWriteFormatInfo::GetCreator | ( | | ) | |
| pure virtual |
Returns the creator that should be used when creating a new file to contain the image data.
- Returns
- The file creator type for the new file
| virtual void IImageWriteFormatInfo::GetExtension | ( | PMString * | extension | ) | |
| pure virtual |
Returns the extension that should be used when creating a new file to contain the image data.
- Parameters
| extension | OUT Pointer to the PMString to fill with the file extension for the new file |
| virtual OSType IImageWriteFormatInfo::GetFileType | ( | | ) | |
| pure virtual |
Returns the file type that should be used when creating a new file to contain the image data.
- Returns
- The file type for the new file
| virtual void IImageWriteFormatInfo::GetFormatName | ( | PMString * | formatName | ) | |
| pure virtual |
Returns the format name for this filter.
- Parameters
| formatName | OUT Pointer to the PMString to fill with the format name |
| virtual bool16 IImageWriteFormatInfo::GetImageColorSpaceSupportInfo | ( | uint32 | colorSpace, | | | ImageColorSpaceSupportInfo * | supportInfo | | ) | | |
| pure virtual |
Returns kTrue if the requested colorspace is supported, else kFalse. If kTrue is returned, then the supportInfo structure contains valid information regarding the requested colorspace.
- Parameters
| colorSpace | IN The colorspace for which support information is requested |
| supportInfo | OUT On successful calls, filled with information about the nature of support |
- Returns
- kTrue if the colorspace is supported by the filter, else kFalse
| virtual uint32 IImageWriteFormatInfo::GetMaxHeight | ( | | ) | |
| pure virtual |
Returns the maximum image height supported by the filter
- Returns
- The maximum supported height
| virtual uint32 IImageWriteFormatInfo::GetMaxWidth | ( | | ) | |
| pure virtual |
Returns the maximum image width supported by the filter
- Returns
- The maximum supported width
| virtual WidgetID IImageWriteFormatInfo::GetPreferencesPanel | ( | | ) | |
| pure virtual |
Returns the WidgetID of the panel to add to the Export Preferences dialog, if any.
The filter is responsible for setting the panel's parent to 'ImageExportUI' via the IDListPair resource definition of the panel and the 'Visible' field of the panel's resource definition to kFalse.
At export time, the export provider will ask the filter for its WidgetID. If the WidgetID is valid, the provider will use the WidgetID to query for the panel's IID_IUIDDATA and use it to set the source UID to be used to initialize the panel. Afterwards, the provider will show the panel, allowing the IntializeFields() method of the IDialogController for the panel to be called.
- Returns
- The WidgetID of the filter's preferences panel, or kInvalidWidgetID if it doesn't have one
