ImageConverter¶
ImageConverter is the BaseConverter subclass selected by ConverterFactory for .gif/.jpg/.jpeg/.png source files. It produces exactly one output page per source image and stretches the image to fill the entire page frame, with no cropping or aspect-ratio preservation logic.
Purpose¶
- Convert a single raster image to a single-page PDF (BR-SFC-003, BR-SFC-016).
- Stretch the source image to fill the full output page frame (BR-SFC-017).
- Identify itself to
ConverterFactoryand downstream consumers as theImageconversion type.
Context¶
- Namespace:
PdfAPI.SyncFusionCore - Assembly/package:
PdfAPI.SyncFusionCore(Pdf.Local.ClientNuGet package)
Public members¶
| Member | Signature | Purpose |
|---|---|---|
| ImageConverter | ImageConverter() |
Creates a ready-to-use ImageConverter instance for ConverterFactory to invoke against raster image source documents (.gif/.jpg/.jpeg/.png); the constructor body is empty*, so no state is established beyond the base type's fields. |
| ConversionType | override SourceConversionType ConversionType { get; } |
Returns SourceConversionType.Image, identifying this converter's source format to ConverterFactory and to the assembled PdfResult. |
Inherited public members¶
Members in this section are inherited from BaseConverter in PdfAPI.SyncFusionCore. They are available on this type through inheritance.
| Member | Signature | Purpose | Origin |
|---|---|---|---|
| Convert | PdfResult Convert(Stream stream, ConvertRequest request) |
Executes the full conversion: times the operation, invokes ConfigureConverter and ConvertItem, and assembles a PdfResult with Status, Elapsed, and PdfProcessorType = Syncfusion; captures rather than propagates conversion exceptions (BR-SFC-006, BR-SFC-010). |

Behavioral notes¶
- Because the image is stretched to the full page frame rather than fit with letterboxing, an image whose aspect ratio differs from the target page will appear distorted in the output PDF (BR-SFC-017).
- A conversion failure is captured by the inherited
Convertmethod and reported through the result rather than thrown (BR-SFC-010).
Constraints and usage notes¶
- Not intended to be constructed directly by application code;
ConverterFactoryconstructs and invokes it based on the source file extension. - Only single-frame images are supported by this converter; multi-frame TIFF images are handled by
TiffConverterinstead.
