The curve font, color and thickness is given by the HatchLineAppearance , the angle by the HatchLineAngle and the distance to the next hatch line by StartOfNextHatchLine , being either an offset distance or a vector. .extDef NOTE Definition according to ISO 10303 46 The fill area style hatching defines a styled pattern of curves for hatching an annotation fill area or a surface. NOTE If the hatch pattern involves two potentially crossing rows of hatch lines, then two instances of [[IfcFillAreaStyleHatching]] should be assigned to the [[IfcFillAreaStyle]] . Both share the same virtual point of origin of the hatching that is used by the reference hatch line or the PointOfReferenceHatchLine if there is an offset . For better control of the hatching appearance, when using hatch lines with other fonts then continuous, the PatternStart allows to offset the start of the curve font pattern along the reference hatch line if not given, the PatternStart is at zero distance from the virtual point of origin . If the reference hatch line does not go through the origin of the virtual hatching coordinate system , it can be offset by using the PatternStart . NOTE The coordinates of the PatternStart are given relative to the origin of the object coordinate of [[IfcAnnotationFillArea]] , or if present, the FillAreaTarget attribute of [[IfcAnnotationFillArea]] . The measure values are given in global drawing length units, representing a model hatching, and can be translated into drawing units by the TargetScale for a scale depended IfcGeometricRepresentationSubcontext , if provided. .deprecated DEPRECATION The use of PointOfReferenceHatchLine is deprecated. Figure 1 illustrates hatch attributes. Example 1 This example shows simple hatching given by using a curve font continuous at HatchLineAppearance. The distance of hatch lines is given by a positive length measure. The angle here 45 if measures in degree is provided by HatchLineAngle. The PatternStart is set to NIL in this example. Example 2 This shows hatching from example 1 with using a different curve font at HatchLineAppearance. The distance of hatch lines is given by a positive length measure, therefore the font pattern start is at a point at the next hatch line given by a vector being perpendicular to the point of origin at the reference hatch line. The PatternStart is set to NIL in this example. Example 3 This example uses hatching from example 2 with a vector to determine the pattern start of the next hatch lines. The pattern start is the beginning of the first visual curve font pattern segment at IfcCurveFont.CurveFont. The PatternStart is set to NIL in this example. Example 4 This example uses hatching from example 3 where the pattern start is offset from the point of origin at the reference hatch line. That is, the first visible curve font pattern segment now does not start at the point of origin at the reference hatch line. Example 5 This example uses hatching from example 4 where the hatch pattern is shifted against the underlying coordinate system. The point that is mapped to the insertion point of the IfcAnnotationFillAreaOccurrence now has an X and Y offset from the start of the reference hatch line. That is, the reference hatch line now does not go through the insertion point of the hatching. Example 6 This example shows use of [[IfcFillAreaStyleHatching]] attributes for two [[IfcFillAreaStyleHatching]] s within one [[IfcFillAreaStyle]]. Note that the PatternStart now displaces both the reference hatch line from the point of origin and the start of the curve pattern. This can be used in cases when more than one [[IfcFillAreaStyleHatching]] is used in an [[IfcFillAreaStyle]] in order to place rows of hatch lines with an offset from each other.

In contrary to the [[IfcImageTexture]] the [[IfcPixelTexture]] holds a 2 dimensional list of pixel color and opacity directly, instead of referencing to an URL. The following definitions from ISO IEC 19775 1 X3D Architecture and base components X3D Specification http www.web3d.org x3d specifications apply The PixelTexture node defines a 2D image based texture map as an explicit array of pixel values image field and parameters controlling tiling repetition of the texture onto geometry. Texture maps are defined in a 2D coordinate system s, t that ranges from 0.0 to 1.0 in both directions. The bottom edge of the pixel image corresponds to the S axis of the texture map, and left edge of the pixel image corresponds to the T axis of the texture map. The lower left pixel of the pixel image corresponds to s 0.0, t 0.0, and the top right pixel of the image corresponds to s 1.0, t 1.0. The Image field specifies a single uncompressed 2 dimensional pixel image. Image fields contain three integers representing the width, height and number of components in the image, followed by width height hexadecimal values representing the pixels in the image. Pixel values are limited to 256 levels of intensity that is, 0x00 0xFF hexadecimal . 1. A one component image specifies one byte hexadecimal value representing the intensity of the image. For example, 0xFF is full intensity in hexadecimal 255 in decimal , 0x00 is no intensity 0 in decimal . 2. A two component image specifies the intensity in the first high byte and the alpha opacity in the second low byte. 3. Pixels in a three component image specify the red component in the first high byte, followed by the green and blue components for example, 0xFF0000 is red, 0x00FF00 is green, 0x0000FF is blue . 4. Four component images specify the alpha opacity byte after red green blue e.g., 0x0000FF80 is semi transparent blue . A value of 00 is completely transparent, FF is completely opaque, 80 is semi transparent. Note that alpha equals 1.0 transparency , if alpha and transparency each range from 0.0 to 1.0.

The bottom edge of the image corresponds to the S axis of the texture map, and left edge of the image corresponds to the T axis of the texture map. The lower left pixel of the image corresponds to s 0, t 0, and the top right pixel of the image corresponds to s 1, t 1. Texture maps may be viewed as two dimensional colour functions that, given an s, t coordinate, return a colour value colour s, t . If multiple surface textures are included in the [[IfcSurfaceStyleWithTextures]] applying them to a geometric item, a mode and optional parameters can be included that blending operations. The RepeatS and RepeatT Boolean flags control whether the texture map is repeated outside the 0.0, 1.0 texture coordinate range, when applied to a geometric surface, or clamped to lie within the 0.0, 1.0 range. The TextureTransform applies a 2D non uniform transformation to the texture before it is applied to a geometric surface. The following definitions from ISO IEC 19775 1 X3D Architecture and base components X3D Specification http www.web3d.org x3d specifications apply These parameters support changes to the size, orientation, and position of textures on shapes. Note that these operations appear reversed when viewed on the surface of geometry. For example, a scale value of 2 2 will scale the texture coordinates and have the net effect of shrinking the texture size by a factor of 2 texture coordinates are twice as large and thus cause the texture to repeat . A translation of 0.5 0.0 translates the texture coordinates .5 units along the S axis and has the net effect of translating the texture 0.5 along the S axis on the geometry s surface. A rotation of π 2 of the texture coordinates results in a π 2 rotation of the texture on the geometry. The center field specifies a translation offset in texture coordinate space about which the rotation and scale fields are applied. The scale field specifies a scaling factor in S and T of the texture coordinates about the center point. scale values shall be in the range , . The rotation field specifies a rotation in radians of the texture coordinates about the center point after the scale has been applied. A positive rotation value makes the texture coordinates rotate counterclockwise about the centre, thereby rotating the appearance of the texture itself clockwise. The translation field specifies a translation of the texture coordinates. The following conventions apply center TextureTransform.LocalOrigin rotation TextureTransform.Axis1 scale S TextureTransform.Scale scale T TextureTransform.Scale2 NOTE The definitions of texturing within this standard have been developed in dependence on the texture component of X3D.

msgid "IfcTextStyleFontModel_DEFINITION"
msgstr ".extDef Definition according to W3C for Cascading Style Sheets Setting font properties will be among the most common uses of style sheets. Unfortunately, there exists no well defined and universally accepted taxonomy for classifying fonts, and terms that apply to one font family may not be appropriate for others. For example, italic is commonly used to label slanted text, but slanted text may also be labeled as being Oblique , Slanted , Incline , Cursive or Kursiv . Therefore it is not a simple problem to map typical font selection properties to a specific font. .extDef Font matching Because there is no accepted, universal taxonomy of font properties, matching of properties to font faces must be done carefully. The properties are matched in a well defined order to ensure that the results of this matching process are as consistent as possible across user agents assuming that the same library of font faces is presented to each of them . 1. The user agent makes or accesses a database of relevant CSS1 properties of all the fonts of which the UA is aware. The UA may be aware of a font because it has been installed locally or it has been previously downloaded over the web. If there are two fonts with exactly the same properties, one of them is ignored. 2. At a given element and for each character in that element, the UA assembles the font properties applicable to that element. Using the complete set of properties, the UA uses the font family property to choose a tentative font family. The remaining properties are tested against the family according to the matching criteria described with each property. If there are matches for all the remaining properties, then that is the matching font face for the given element. 3. If there is no matching font face within the font family being processed by step 2, and if there is a next alternative font family in the font set, then repeat step 2 with the next alternative font family . 4. If there is a matching font face, but it doesn t contain a glyph for the current character, and if there is a next alternative font family in the font sets, then repeat step 2 with the next alternative font family . 5. If there is no font within the family selected in 2, then use a UA dependent default font family and repeat step 2, using the best match that can be obtained within the default font. The above algorithm can be optimized to avoid having to revisit the CSS1 properties for each character. The per property matching rules from 2 above are as follows 1. font style is tried first. italic will be satisfied if there is either a face in the UA s font database labeled with the CSS keyword italic preferred or oblique . Otherwise the values must be matched exactly or font style will fail. 2. font variant is tried next. normal matches a font not labeled as small caps small caps matches 1 a font labeled as small caps , 2 a font in which the small caps are synthesized, or 3 a font where all lowercase letters are replaced by upper case letters. A small caps font may be synthesized by electronically scaling uppercase letters from a normal font. 3. font weight is matched next, it will never fail. See font weight below. 4. font size must be matched within a UA dependent margin of tolerance. Typically, sizes for scalable fonts are rounded to the nearest whole pixel, while the tolerance for bitmapped fonts could be as large as 20 . Further computations, are based on the font size value that is used, not the one that is specified. The inherited Name attribute is used to define the font name, particularly in cases, where no list of font families are provided.
