ENHANCEMENT TOOLS
The following image enhancement tools are available:
Sharpen tool
Smooth tool
Invert tool
Speckle Correct tool
The Sharpen tool applies a sharpening filter to the selected image. The sharpening filter should
make the edges of bands more pronounced. However, there may also be an increase in
graininess.
The Smooth tool applies a smoothing filter to the selected image. This can be useful if the
image has specks of dust or bubbles present. However, there may also be a reduction in band
sharpness.
The Invert tool reverses the image, i.e. white appears black, black appears white. This can be
useful when trying to view very faint bands on an image.
The Speckle Correct tool can be used to remove white speckles or 'hot pixels' from an image.
The Flip Vertical tool mirrors the selected image in the vertical plane. This can be useful if the
sample has been placed in the Darkroom the wrong way round.
The Flip Horizontal tool mirrors the selected image in the horizontal plane. This can be useful
if the sample has been placed in the Darkroom the wrong way round.
The Define area to be cropped tool enables you to select an area of the selected image so
that you can isolate the chosen portion of the image from the rest of the image in order to view
that portion more closely. Select the Define area to be cropped icon and draw a rectangle that
covers the area you want to examine. The rectangle is outlined in pink and filled with a
transparent pink fill. Select the fill area and the selection rectangle can be accurately positioned
by dragging and resized using the visible 'handles'. This enables you to finely control the
selected area of interest. Selecting the Define area to be cropped tool once more cancels the
selection rectangle just made, but leaves the cursor in selection mode, allowing you to restart
the selection process. Selecting the Define area to be cropped tool twice more cancels the
selection rectangle just made and also cancels the selection function.
