IC Imaging Control ActiveX

ImageBuffer

ImageBuffer

An ImageBuffer object contains the image data of one frame. IC Imaging Control's internal ring buffer consists of ImageBuffers.

All image buffers of the ring buffer can be retrieved from the ImageBuffers collection.

Example

This example illustrates how to obtain the first available image buffer:

Dim Buffer As ImageBuffer
Set Buffer = ICImagingControl1.ImageBuffers.Item(1)

Information

Introduced in IC Imaging Control 1.x

Properties

Property Description
FrameType

Returns a FrameType object describing the image format of this ImageBuffer.

ImageDataPtr

Returns the address of the first byte of the image data.

Lines

Returns the number of lines in this ImageBuffer.

Locked

Returns True if the ImageBuffer is locked.

Picture

Returns a Picture object created from the data in the buffer.

PixelPerLine

Methods

Method Description
ForceUnlock

Reduces the lock count immediately to 0. Therefore, an image buffer is unlocked, enabling IC Imaging Control to copy an image to it.

GetDib

Returns a handle to a DIB for further imaging toolkits. This property is only available in the COM interface (Visual Basic 6).

GetImageData

Provides direct access to the data in the image buffer. This property is only available in the COM interface (Visual Basic 6).

Lock

Locks the buffer

ReleaseImageData

Releases a SAFEARRAY that was acquired by a call to ImageBuffer.GetImageData. This property is only available in the COM interface (Visual Basic 6).

SaveAsBitmap

Saves the contents of the buffer to a bitmap file on disk.

SaveAsJpeg

Saves the contents of the buffer to a JPEG compressed file to disk.
