In AKVIS Sketch, different tools become visible depending on the active tab, Before or After.
|Toolbar, Before tab||Toolbar, After tab|
You can use the buttons and to undo/redo the operations made with the tools: , , , , , , .
Pre-Processing Tools (on the Before tab):
You can drag the preview square to any position with the left mouse button or with the double click. This lets you quickly preview the effect in different areas of the image. To compare the result of automatic conversion with the original picture, click and keep mouse pressed within the preview area.
You can adjust the preview window size in the program's preferences .
Note: This feature is only available for the advanced licenses (Home Deluxe, Business) in the Classic style.
Add the guiding lines with this tool, and the program will re-make the drawing following the new direction. The changes will be shown in the preview window. To re-start the image processing, click on the button .
You can adjust the parameters that influence on the effect in a pop-up box that appears when right-clicking in the image:
Zone of Influence. The parameter changes the width of the area affected by guiding lines. The higher the value, the more hatching will follow the direction of the lines.
Preserve Edges check-box. When this check-box is enabled, the effect does not extend to the outlines.
Hint: You can save guiding lines to a .direction file with the button, and load them with for further processing. Loaded lines automatically adapt to the image size.
In the Classic style, when Sketch & Photo / Sketch & Blur is active, the Eraser can operate in one of these modes and erase:
- all lines (both guiding lines and zone lines of the background effects);
- only area outlines (background effects);
- only guiding lines (direction of the strokes).
You can also adjust the Size of the pencils and eraser in a pop-up box appearing with a right click of the mouse.
Post-Processing Tools (on the After tab, for Deluxe/Business):
Attention! The post-processing tools , , are only available under the Home Deluxe/Business licenses, on the After tab. Use them at the final step. If you re-run the image processing , the changes made with the post-processing tools will be lost!
The tools' options are shown in a pop-up box which appears after right-clicking in the image.
Size (1-50). The line width which can be drawn with the tool.
Hardness (0-100) defines the blurriness of the tool's edges. The less the value the more blurry the tool's edges become.
Opacity (1-100). The opacity of the strokes drawn with the pencil. The lower the value, the more transparent the lines will be.
Smoothing. The check-box eliminates the irregularity of the line. The strokes drawn with the tool get smoothed out.
Refined Lines. The check-box changes the appearance of the pencil strokes. When this option is enabled, the ends of the lines become thinner, the drawing looks more refined and elegant.
Size (1-1000). The width of the transparent line which the eraser leaves behind.
Hardness (0-100). The amount of blurriness of the brush's edge. As the value of this parameter increases the edge of the brush becomes harder. Near 100% the border between erased and unerased areas will be more distinct; at lower values the boundary between these areas will be smoother.
Strength (1-100). The amount of influence on an image. As this parameter's value is increased, the degree of transparency left by the brush increases.
The tool's parameters:
Restore to Original. If the check-box is enabled, the tool edits all changes, weakening the drawing effect, as well as the result of the post-processing tools. If the check-box is disabled, the brush changes only strokes drawn with the pencil but does not affect the result of the photo to sketch conversion.
Size (1-1000). The width of a line made by the brush.
Hardness (0-100). The blurriness of the tool's edges. The less the value the more blurry the tool's edges become. At value 100% the border between the brush's edges and the background is very distinct; at lower values the transition between these areas is smoother.
Strength (1-100). The degree of restoration to the original state. At lower values there will be less restoration and more blending with the effect; at value 100% the original image will be restored more completely.
You can change the crop area by dragging the sides and the angles of the bounding frame.
To apply the result and remove the areas outside the frame, press OK or use Enter. To cancel the operation and exit the tool, press Cancel or use the Esc-key. To restore the original area keeping the tool active, press Reset button.
Adjust the crop options:
You can choose the size of the crop rectangle from the Ratio drop-down list or enter your custom aspect ratio.
If the External Area check-box is enabled, you can change the color and opacity of the outer parts.
Additional Tools (available on both tabs, for all licenses):
Double-clicking on the tool's icon on the Toolbar makes the image fit the window.
Double-clicking on the tool's icon makes the image scale to 100% (actual size).
