Image Device Information Settings
The following table lists the device information settings for rendering in IMAGE, IMAGEPrintPreview and IMAGEPrint formats.
Image Device Information Settings
| Name | Type | Description |
|---|---|---|
| OutputFormat | String | Defines the output format of the produced image. Supported formats are: BMP, EMF, EMFPLUS, GIF, JPEG, PNG, or TIFF. The default value for IMAGE rendering extension is TIFF. The default value for IMAGEPrint and IMAGEPrintPreview rendering extensions is EMF. |
| StartPage | Integer | The first page of the report to render. A value of 0 indicates that all pages are rendered. |
| EndPage | Integer | The last page of the report to render. |
| DpiX | Integer | The resolution of the output image in x-direction. The default value is 96. |
| DpiY | Integer | The resolution of the output image in y-direction. The default value is 96. |
| TiffCompression | String | Specifies the compression scheme of the output TIFF file. Respected only when OutputFormat is set to TIFF. Supported compression kinds are: LZW, CCITT3, CCITT4, RLE, or NONE. The default value is LZW. |
| TextRenderingHint | string | Sets the rendering mode for text using a TextRenderingHint enumeration member. The default value depends on the machine settings - if it has ClearType enabled, then ClearTypeGridFit will be used. Otherwise the rendering algorithm will use AntiAliasGridFit hinting. If text rendering hinting is not supported, the SystemDefault value will be used. |
