1. Pen Window


1.1 Pen of Fingertip/Burn/Dodge

The pen displayed on pen window would be 5 kinds with the increase in the kind of pen.
The key corresponding to pen position is in order of A/S/D/F/G.
* Gradient tool shortcut would change into from "G" to "J."

1.2 Tone effective button (only on PLUS)

It is the button of the left-hand side on gamma revising.
This should be effective in order to use "tone function" with pen.

Since this specification is set as the object of "save" of pen setup, please be careful it is easy to be turned off automatically when other pen setup is loaded.

1.3 Gradient effective button

It is the button of the right-hand side on gamma revising.
This should be effective in order to use "gradient function" with pen.

Since this specification is set as the object of "save" of pen setup, please be careful it is easy to be turned off automatically when other pen setup is loaded.

When it makes effective, the color of pen would come to be acquired from gradient.
Gradient pattern becomes the gradient performed at the end.
In order to specify gradient coordinates without drawing gradient, please press +SHIFT by gradient tool after starting drug.

1.4 Density slider

It is the slider which located at the bottom.B
The density of a pen is expressed.

The density of each tool and the density of pen which are displayed on a control window have been independent.
In oC2, density was common to all tools.

2. Function of Layer


2.1 18 kinds of new layer modes

18 kinds of layer modes in below were added.
These modes do not guarantee compatibility with other applications.

Subtraction(Nega), Screen, Overlay,
Soft Light, Hard Light, Linear Light, Vivit Light, Pin Light,
Difference, Exclusion, Darken, Lighten, Burn, Dodge,
Hue, Saturation, Color, Luminosity

2.2 Dither composition mode

This is specified at layer setting option window.
When it makes as effective, dither concentration will be determined according to layer alpha and blend.
This could be specified not only to standard layer but also to all layer modes.

2.3 Layer addition dialog

When adding layer as new, initial layer mode, initial color, transparent opaque, and name could be specified.
(only on PLUS) The larger opaque portion of layer would be, the lighter operation would be.

The command "Create SUB layer (create new subtraction layer)" was deleted. Please use the addition of layer.

2.4 The improvement of combination with lower layer

It corresponded to the layer combination with other kinds or the same kind to some extent.

However, since layer mode increased, there are some which cannot be combined not much well, depending on combination.
When combining with lower layer, please make sure "Undo" to be effective for safety.

3. Function of Tone (only on PLUS)


3.1 How to use

In Tone window, the tone (texture) used currently would be created, or specified and selected.
In order to use tone with pen actually, it is necessary to make tone be effective in Pen window.

Please refer to 1.2 about specification in Pen window. >>1.2

3.2 Inclusion tone pattern

It could be created with the menu "Create new tone" of Tone window.

Although DPI can be specified, actually important one becomes line interval for every image since DPI is not fixed.
If "Blur" is enlarged, 2 value boundaries would become smooth. When it is specified as 0, it would be the same as 2 value in fact.
The number of lines and the angle of the pattern created are not necessarily strictly in agreement with the specified value. Please be careful about this.

3.3 Taking in Tone

After opening picture to take in, "Create by luminosity of image" should be done.
The picture in this case is the best of the pattern in which a smaller repetition is possible.

As for a taking-in tone picture, the whole is taken in by the event!
An event becomes huge shortly after using a huge taking-in picture tone.

In the present system, when the collection of tones is opened, it is not good for registering many taken-in huge pictures in order to read all patterns.

3.4 Saving and reading the collection of tones

The created tone could be saved and read as "the collection of tones".

Since taking-in tone presses memory, please create it as not much data is included.

4. Function of Gradient


4.1 How to use

In Gradient window, the gradient to be used is created and selected.
The first gradient is fixed to the foreground and background color gradient as "2 Color fixation".

In order to use Gradient, there are two methods. One is the method of drawing direct gradient with Gradient tool, and another one is the method of using it as color of pen.

4.2 Inclusion pattern

In addition to alignment, circular and spokewise type could be chosen.

A repetition unit could be the distance dragged on alignment and circular.
An angle could be limited per 15 degrees by dragging + CTRL.

4.3 Editing gradient

The complicated gradient which combined two or more colors could be created.
Transparency could also be specified on color.

4.4 Saving and reading the collection of tones

The created gradient could be saved and read as "the collection of gradient".
The inclusion gradient "**2 color fixed **" could not be saved and read.

4.5 Using as pen color

It is possible to color by pen using the present gradient color.

Please refer to 1.3 about specification in pen window. >>1.3

5. User Interface


5.1 Docking of window

Pen window and all tool windows other than tool box could be made to dock freely.

Please drag +CTRL not to dock windows.

5.2 Additional zoom percentage (only on PLUS)

6%, 10%, 15%, 33%, 66%, 75%, 125%, 175%, 250% of zoom percentage are added.
(The value of zoom may still be adjusted.)

5.3 Indication of anti-alias (only on PLUS)

While indicating middle magnifications other than integral multiple display and indicating by rotation, it can indicate by anti-alias.
In order to use Anti-alias display, the 1GHz of the above CPUs is recommended.

It is necessary to be effective anti-alias display at "Preferences".

5.4 Control window and Coordinates display

Coordinates are displayed into the control window.

Moreover, density bar became to be displayed on control window for every tool.
Density became to be memorized independently for every tool.

5.5 Tool of move layer + selection

The tool which moves layer and the selection range simultaneously into layer move tool was added.

6. Function of File


6.1 PSD file support (only on PLUS)

It corresponded to saving and reading of PSD file (Photoshop format).
It is possible to exchange with layer structure maintained. It does not correspond to the function which is not included in oC3 such as adjustment layer, effect layer, and layer set.

6.2 PNG file support

It corresponded to saving and reading of PNG file.
It also corresponds to PNG format with an alpha channel.

6.3 Saving and reading layer

The layer selected currently could be saved at file.
Images cannot be saved with opaque or with attributes such as layer mode and position information.
Format which can be saved is only PNG and BMP.

BMP is saved in Windows Bitmap 32bit form.
Please choose PNG form when passing data to other applications since opaque in this form is not Windows standard.

7. 10 kinds of New Filter


7.1 Gauss blur

This is the Gauss blur filter which specifies numerical value.

7.2 Sharp

This is the Shrp filter which specifies numerical value.

7.3 Clouds

Clouds pattern is created by using foregraund and background color.
It might take longer time to do so.

7.4 Rock

Rock pattern is created by using foregraund and background color.
It might take longer time to do so.

7.5 Wave

It changes the image as wavy.

7.6 Twirl

A center is specified and image would be twisted.

7.7 Lighting

This takes out an effect which has a light (light source) on image.

7.8 Emboss

It gives the embossing (relief) effect to image.

7.9 Floor

This arranges image in on a tile and creates a pattern like floor.
Please be careful about its size since the image taken in here is contained in Event.

7.10 Tiles

This creates patterns that it covered with the square or the triangle.

8. other Functions


8.1 Optimization of operation (only on PLUS)

In oC3 Plus, the data structure is changed in order to treat huge data.
oC3 Plus can create more layers rather than oC2 and oC3.

Especially as for some heavy processings, improvement in the speed is given individually.
In some processings, the more display area is narrow, the more it operates at high speed.
Special high speed processing is done only in PLUS.

8.2 Font preview

With "text" and "text selection range" tool, font preview is displayed not only font window but on the screen.

The preview of "text selection range" tool is not previewed at selection range. It is previewed at the "usual font drawing"

8.3 Modify selection range (Expand and Contract) (numerical specification)

The selection range could be modified by specifing numbers.

8.4 Color range

Color range could be specified on the image of selection range.

8.5 Other changes

  • The angle limited function in +Ctrl on straight line tool and others became per 15 degrees.
  • The quality of image in "resolution (change of image resolution)" was improved.
  • Width and height can be independently specified at the grid.
  • Only selection within the limits could be pasted when pasting to clip board with the selection range.
  • It changed to separate to linear when performing "separate (separating the selection range into another layer.
