Some arguments in ART component function calls are pointers to the internal ART component structures and data types such as ART_MARK_ATTRIBUTES structure that determines general attributes used by every ART mark. There are such important data types as ART component named blocks (ART_NAMED_BLOCK) that determine, for instance, mark's coordinates and orientation (ART_BLOCK_ANODAT) or the name of file for image marks (ART_BLOCK_FILNAM). For the full list of structures and data types currently provided by ART component please see i_ART.h file.
- You can see ART_MARK_ATTRIBUTES structure reference below:

|
Members:
| dwType |
The type of mark:
|
| rcBounds |
Rectangle in image units. Can be a rectangle or two points. |
| rgbColor1 |
The main color; for example, the color of all lines, all rectangles, and standalone text. |
| rgbColor2 |
The secondary color; for example, the color of the text of an Attach-a-Note. |
| bHighlighting |
If TRUE the mark is drawn highlighted. Highlighting performs the same function as a highlighting marker on a piece of paper. Valid only for lines, rectangles and freehand. |
| bTransparent |
If TRUE the mark is drawn transparent. A transparent mark does not draw white pixels: transparent replaces white pixels with whatever is behind those pixels. Available only for images. |
| dwLineSize |
The width of the line in pixels.
 |
It is ignored when setting dwPenStyle for a straight line mark.
|
|
| lReserved1[2] |
Reserved; must be set to 0. |
| lfFont |
The font information for the text, consisting of standard font attributes of font size, name, style, effects, and background color. |
| dwReserved2 |
Reserved; must be set to 0x0FF83F. |
| dwTime |
The time that the mark was first saved, in seconds, from 00:00:00 1-1-1970 GMT. Every annotation mark has time as one of its attributes. If you don't set the time before the file is saved, the time is set to date and time that the save was initiated. This time is in the form returned by the "time" C call, which is the number of seconds since midnight 00:00:00 on 1-1-1970 GMT. If necessary, refer to your C manual for a more detailed description. |
| bVisible |
If TRUE the mark is currently set to be visible. Annotation marks can be visible or hidden. |
| Reserved3[11] |
First 9 elements and Reserved[10] are reserved and must be set to 0. Value Reserved[9] is used by ImageGear to store DISABLE_PPM_FOR_FONTS mark attribute. Its interpretation is identical with global control parameter ART_CONTROL_DISABLE_PPM_FOR_FONTS but affects only one annotation. 2 helper macro-functions has been introduced to get and set this attribute.
- AT_BOOL ART_DISABLE_PPM_FOR_FONTS_GET(LPART_MARK_ATTRIBUTES pMa);
- AT_BOOL ART_DISABLE_PPM_FOR_FONTS_SET(LPART_MARK_ATTRIBUTES pMa, AT_BOOL bNewValue);
