Namespace: Euresys::Open_eVision_2_5
Methods
This method attaches the ROI to another ROI or image. Only ROIs can be attached. An image can never be attached to another image or ROI. Optionally, the ROI can be moved and resized after attachment by supplying additional parameters.
This method reduces the ROI size so that it is completely contained within its topmost parent image bounds (if such an image exists at the top of the hierarchy). This means that, after calling this method, either the ROI has a zero size, or all of its pixels map to valid pixels of the underlying image buffer. If the ROI is already contained within its parent image bounds, then this method does nothing.
Moves the specified handle to a new position and updates all placement parameters of the ROI.
Draws an ROI/image in a device context.
Draws a rectangular frame around an image or ROI.
Draws a rectangular frame around an image or ROI.
Gets or sets the Author attribute of the ROI/image. This is a convenience property that allows storing some information in the ROI/image. Please note that not all file formats preserve this information.

Gets the number of storage bits per pixel.
Gets or sets the color system used by this image, as defined by the EColorSystem enumeration.
Gets the pitch of a column (number of bytes between two horizontally adjacent pixels). For BW1 (one bit per pixel) images, this value is undefined.
Gets or sets the Comment attribute of the ROI/image. This is a convenience property that allows storing some information in the ROI/image. Please note that not all file formats preserve this information.
Gets or sets the Date attribute of the ROI/image. This is a convenience property that allows storing some information in the ROI/image. Please note that not all file formats preserve this information.
