Convert to lines and tones (EX only)

In Clip Studio Paint EX, you can convert images or 3D models into separate layers with lines and screentone shading.

Extracting lines from images

You can convert a selected layer into a folder containing separate layers for the lines and tones.

Select the layer you want to convert, then use the Layer menu > Convert to lines and tones to open the dialog.Adjust the settings to get the desired result, then tap OK to convert the layer.You can use the Preview setting to check the result first.

(1)Posterize first

If turned on, the original layer is posterized before outline extraction.The levels can be adjusted with the levels slider.

(2)Levels slider

Adjust the grayscale gradient to extract as an outline.The stripes show the proportion of each level of shading.Use the nodes to adjust the grayscale gradient by dragging the nodes horizontally to adjust the levels.You can tap an empty space on the bar to add a new node, or drag nodes out of the slider to remove them.

(3)Black fill

Set the areas to be filled in black.You can set the threshold by entering a value or adjusting the slider.

(4)Line width

You can set the width of the outline by entering a value or adjusting the slider.

(5)Method of edge detection

Defines how edges are detected in order to extract the outline.The settings shown depend on the method selected.

Process 1

The outline is extracted based on Threshold of edge and Direction of detection.

·Edge threshold: Set the gray density threshold to extract as outline.The smaller the value, the more lines will be detected, making the outline wider.

·Direction of detection: Specify the direction in which to detect the outline.If turned off, outline detection is weaker.

Process 2

The outline is extracted based on Threshold of edge height and Threshold of gradient variation. This method is suitable when a more delicate expression is required.

·Edge height: Adjust the height of the edge to detect as an outline.The smaller the value, the weaker the edge, making even small changes detected as a line.

·Line curvature: Adjusts the continuity of the detected outline based on variation in thickness.The larger the value, the more likely it is to have short segments.

(6)Tone work

Turn this on to adjust the tones.If Tone on the Layer Property palette is on, you can carry over the settings for Tone.

(7)Posterization

When turned on, you to adjust the density of the tone using Posterization control.

(8)Levels slider (tones)

Adjusts the density of the tones.Drag the nodes horizontally to adjust the levels of each density.Tap an empty space on the bar to add a new node, or drag nodes out of the slider to remove them.

(9)Type

Select the pattern for the screentone.(The Type setting cannot be previewed on the canvas.)

(10)Frequency/Angle

Specify the frequency and angle of the pattern.When Type is set to Noise, the Size and Factor settings appear instead.

Extracting lines from 3D models

You can convert a 3D model into a folder containing separate layers for the outlines and tones.

Select the layer you want to convert, then use the Layer menu > Convert to lines and tones to open the dialog.Adjust the settings to get the desired result, then tap OK to convert the layer.You can use the Preview setting to check the result first.

(1)Raster layer/Vector layer

Choose whether to extract the lines to a raster layer or a vector layer.

(2)Line width

You can set the width of the outline by entering a value or adjusting the slider.

(3)Accuracy of detection

Adjust the accuracy with which to detect the lines.You can turn on Adjust accuracy according to scale to adjust the precision depending on the size of the 3D material.

(4)Emphasize outline

Set how much the outline will be emphasized.

(5)Depth

Turn this on to give depth to the lines, and use the graph to adjust the results.Turn on Apply only to outer line to make the setting only affect the outlines of the material.
You cannot use this setting when the Method of edge detection is set to Process 2.

(6)Smooth

Turn this on to smooth the outlines of 3D layers.A larger level value makes the outline smoother.

(7)Extract line of texture

When turned on, the texture of the 3D layer will also be converted.

(8)Posterize first

When turned on, the original layer is posterized before extracting the lines.The gradient can be adjusted using the levels slider.

(9)Levels slider

Adjust the grayscale gradient to extract as an outline.The stripes show the proportion of each level of shading.Use the nodes to adjust the grayscale gradient by dragging the nodes horizontally to adjust the levels.You can tap an empty space on the bar to add a new node, or drag nodes out of the slider to remove them.

(10)Black fill

Set the areas to be filled in black.You can set the threshold by entering a value or adjusting the slider.

(11)Line width

You can set the width of the texture lines by entering a value or adjusting the slider.

(12)Method of edge detection

Defines how edges are detected in order to extract the outline.The settings shown depend on the method selected.

Process 1

The outline is extracted based on Threshold of edge and Direction of detection.

·Edge threshold: Set the gray density threshold to extract as outline.The smaller the value, the more lines will be detected making the outline wider.

·Direction of detection: Specify the direction in which to detect the outline.If turned off, outline detection is weaker.

Process 2

The outline is extracted based on Threshold of edge height and Threshold of gradient variation. This method is suitable when a more delicate expression is required.

·Edge height: Allows you to adjust the height of the edge and detect it as an outline.The smaller the value, the weaker the edge, making even small changes detected as a line.

·Line curvature: Adjusts the continuity of the detected outline based on variation in thickness.The larger the value, the more likely it is to have short segments.

(13)Tone work

When turned on, you can set the tone.If Tone on the Layer Property palette is turned on, you can carry over the same settings for Tone.

(14)Posterization

When turned on, you to adjust the density of the tone using the levels slider.

(15)Levels slider (tones)

Adjusts the density of the tones.The stripes show the proportion of each level of shading.Use the nodes to adjust the grayscale gradient by dragging the nodes horizontally to adjust the levels.You can tap an empty space on the bar to add a new node, or drag nodes out of the slider to remove them.

(16)Type

Select the pattern for the screentone.The Type setting cannot be previewed on the canvas.

(17)Frequency/Angle

Specify the number of screentone lines per inch, and the angle of the screentone pattern.When the Type is set to Noise, the Size and Factor settings appear instead.

(18)Preview

Shows a preview of the results on the canvas.
