- ImageGear.Core.ImGearRasterPage object to import into the Recognition engine.
Return Value
New ImGearRecPage instance.This method imports an image from ImageGear into the Recognition engine. This step is necessary before any recognition tasks can be performed on an image.
There are a few requirements that an image must meet in order to be successfully imported into the Recognition engine:
- The image must be a raster image, hence the ImageGear.Core.ImGearRasterPage type of the input parameter. You can cast from ImGearPage to ImGearRasterPage when calling this method, as long as the image is a raster image.
- The image must have correct resolution information. Allowed range for the resolution is 75 to 2400 DPI. The best resolution for B/W images is 300 or 400 dpi. For grayscale or color images the optimal recogniton resolution is 150 to 300 dpi. Some recognition modules apply additional restrictions on image resolution or physical size. See Specifications for the Recognition Modules section for more information.
- For B/W images, both the image width and height must not exceed 32000 pixels. For other types of images, both the image width and height must be within 16 and 8400 pixels.
- To allow saving recognized data to Microsoft Word formats both the physical width and height of the image (defined by image resolution and pixel dimensions) must be between 0.1 and 22 inches.
