Image Processing
| Product: | SnagIt |
| Platform: | Win 98 and above |
| Version: | 7 and above |
SnagIt's professional Image Processing options can be used to modify your captures in many different ways. Use one alone, or combine them to get exactly the right look. Place your cursor over the Image Processing option and a fly-out menu shows your choices. Click to select the one you wish to use.
With most of the effects, upon selection an additional preview window will appear. You can adjust the sliding bar on this window to choose the intensity level of the effect. After adjusting the sliding bar, you can choose OK to change the image or Cancel to reject the change.
These effects can also be applied to just a region of the image. Use the cursor to select a region of the image, and then apply the effect. Here are just a few ways that the image processing features can enhance your captures:
Applying Image Processing Effects from within the Preview Window
Note: These effects can be applied to a region of the image. Use the cursor to select a region of the image, and then apply the effect.
Select an image in the Preview Window. Select Effects > Image Processing. A fly-out menu shows additional choices. Click to select the effect you want to use. Adjust the sliding bar if needed. (Edge Enhance works automatically, Underlay asks you to select an image to underlay, and Emboss asks you to select a direction.) Click OK. Choose Finish to direct the image to the desired output.
Image Processing Options
To access Image Processing options, from within the Preview Window choose Effects > Image Processing. A fly-out menu appears, from which you can choose the desired effect.
The following table describes each of the Image Processing menu options.
|
Option
|
Description & Use
|
|
Posterize
|
Applies a poster effect on the image.
|
|
Mosaic
|
Imposes a mosaic effect on a bitmap by dividing the bitmap into tiles of a specified size and changing the color of all pixels in each tile to the average color of pixels in the tile.
|
|
Average
|
Changes the color of each pixel in a bitmap to the average color of pixels in its neighborhood. This causes a blur effect.
|
|
Median
|
Changes the color of each pixel in a bitmap to the median color of pixels in its neighborhood. This is equivalent to the Average filter, but it is used to decrease noise, rather than add a blur effect.
|
|
Sharpen
|
Increases or decreases the sharpness of the image in the bitmap.
|
|
Add Noise
|
Adds pixels to a bitmap at any location, letting you give the percentage of coverage and the color plane.
|
|
Emboss
|
Applies an emboss effect to a bitmap, letting you give the depth and direction of the effect.
|
|
Oilify
|
Applies an oil-painting effect to the bitmap.
|
|
Underlay
|
Combines two bitmaps so that one looks to be an underlying texture for the other. This is good when the underlying image is a filtered one, such as an embossed image.
|
|
Solarize
|
Applies an effect that mimics the accidental exposure of photographic film to light. It does so by inverting all color data with an intensity value greater than or the same as the threshold that you give.
|
|
Edge Enhance
|
Enhances the edges in the image.
