The images below illustrate the three possible molecule display layouts depending on the position of the title. These layouts can be controlled by the following parameters:

The width and the height can be set either by the constructor of the OE2DMolDisplayOptions class, by calling the OE2DMolDisplayOptions.SetDimensions method or by the SetWidth and SetHeight methods, respectively.
The location of the title area (blue box) can be set by the SetTitleLocation method. The height of the title area (blue arrows) can be modified by invoking the SetTitleHeight method.
The padding around the molecule (red arrows) can be changed by calling either the SetMargin or the SetMargins methods.

**Example of molecule display layouts depending on position of the title**¶
title hidden	title at the top	title at the bottom

Hint

Even though OEDepict TK provides access to manipulate the properties of the atom and bond displays after the OE2DMolDisplay object is constructed, it is highly recommended to determine the style of the depiction by using the OE2DMolDisplayOptions class. Only by knowing all properties (such as labels, font styles and sizes etc.) in advance can ensure the best depiction layout i.e. that the molecule diagram is rendered without any label clippings and the labels are displayed with the minimum number of overlaps.

../../_images/OE2DMolDisplayOptions_SetAtomColor.png

Example of using the SetAtomColor method¶

See also

OE2DMolDisplayOptions.GetAtomColor method
OEColor class
Appendix: Element coloring (CPK) section

Note

The color of the atom also depends on the atom color style (OE2DMolDisplayOptions.GetAtomColorStyle).
Setting atom color style (OE2DMolDisplayOptions.SetAtomColorStyle) to WhiteMonochrome sets white background and black color for all atoms. Likewise, setting atom color style to BlackMonochrome sets black background and white color for all atoms. But, user can choose to have another color for all atoms (in monochrome atom color style) by setting another atom color (OE2DMolDisplayOptions.SetAtomColor) for Carbon atoms. The example in Listing 4 demonstrates setting non-default atom colors in monochrome mode. Setting atom color for other than Carbon atoms sets color of only specified atom types, not for all atoms.

SetAtomColorStyle¶

Sets the style that is used to define the color of the background and the default color of atom labels.

double scale = OEScale.AutoScale;
OE2DMolDisplayOptions opts = new OE2DMolDisplayOptions(width, height, scale);
OEFont font = new OEFont();
font.SetStyle(OEFontStyle.Bold);
opts.SetAtomLabelFont(font);

../../_images/OE2DMolDisplayOptions_SetAtomLabelFont.png

Example of using the SetAtomLabelFont method¶

Note

The color of the atom label fonts also depends on the atom color style (OE2DMolDisplayOptions.GetAtomColorStyle).

It is recommended to use the OE2DMolDisplayOptions.SetAtomPropertyFunctor method to define the atom property labels when the OE2DMolDisplay object is constructed.
