Members
| Member | Value | Description |
|---|---|---|
| BitsPerSample | 258 | Indicates how big a sample is. Typical values are: 1 = Binary; 4 = four-bit gray scale (16 shades of gray); 8 = eight-bit gray scale (256 shades of gray); 24 = 24-bit color. |
| Brightness | 1282 | The scanner's brightness. If available, -3 will set to auto brightness, -2 will auto darken, and -1 will auto lighten. Values from 0 to the ImGearIsisTagChoices MaxValue property incrementally change the brightness. |
| Contrast | 1281 | The scanner's contrast. A value of 0 means auto contrast or no contrast control is available. |
| ImageLength | 257 | Specifies the number of rows of pixels (height) in an image. |
| ImageWidth | 256 | Specifies the number of columns of pixels (width) in an image. |
| PageSize | 1294 | The total area available to the scanner. |
| ResolutionUnit | 296 | Specifies the unit of measurement for XResolution and YResolution. This setting is not available for all scanners and if it is not available, the units are assumed to be DPI. The tag value can be set to any of the values in the ImGearIsisResolutionUnit enum. |
| SamplesPerPixel | 277 | Indicates how many values each pixel uses to represent the data. Possible values are: 1 sample per pixel = Binary (black/white) and gray scale images; 3 samples per pixel = RGB color images. |
| ScanAhead | 1293 | Specifies if the scanning source has enabled the ability to continuously scan pages ahead of the current page the application is processing on those scanners that support this functionality. The tag value can be set to any of the values in the ImGearIsisScanAhead enum. |
| ScanAheadMaxPages | 1404 | If ScanAhead is enabled, this setting specifies the maximum number of pages to scan ahead. A zero value means to scan until the feeder is empty. |
| ScanAheadPages | 1301 | If ScanAhead is enabled and this setting is supported, it determines how many pages have been scanned in ahead. On some scanners this value is not an accurate measurement for how many pages are scanned in ahead. Therefore, use this setting as a general indicator that there are pages waiting that have been scanned in ahead. |
| ScanType | 1300 | Specifies the scanning source on those scanners that support this functionality. The tag value can be set to any of the values in the ImGearIsisScanType enum. |
| XPosition | 286 | Specifies the distance in pixels from the left edge of the page to the start of the image. |
| XResolution | 282 | The scanner's horizontal resolution in DPI (dots per inch). |
| YPosition | 283 | Specifies the distance in pixels from the top edge of the page to the start of the image. |
| YResolution | 283 | The scanner's vertical resolution in DPI. |
