特征表示

MIF点功能指定单个Xandy除任何关联的用户定义属性外，坐标。也可以读取或写入点特征的聚合 - 这对应于MIFMULTI_POINTprimitive type.

MIF点还指定符号。符号由符号编号，颜色和大小定义。如果没有为点实体定义符号，则使用先前的符号。

下表列出了用于控制MIF符号设置的特殊FME属性名称。1MapInfo符号无法旋转。但是，某些第三方附件到MapInfo基于用户定义的rotation属性旋转符号。

MIF font point are very similar to MIF points, but allow a symbol based on a TrueType font to be specified. In addition to the font, may specify rotation, color, shape number, size, and style.

MIF自定义点与MIF点非常相似，但允许将位图图像指定为要绘制的符号。除了图像，颜色，大小和样式之外，还可以指定。

下表列出了用于控制MIF自定点设置的特殊FME属性名称：

MIF MultiPoint功能指定每个由一个定义的多组点数Xandycoordinate. All the points share the same attributes and geometry. This is supported as a homogeneous aggregate feature composed of points, font points or custom points.

The MIF multipoint uses the same attribute names control settings as the points, font points and custom point.

MIF折线特征指定由X和Y坐标序列定义的线性特征。每个折线都有一个与它相关的笔式，指定线的颜色，宽度和笔图案。折线也可以指定它是平滑线，在这种情况下，MapInfo在渲染线时使用曲线拟合算法2MapInfo renders smoothed polylines substantially slower than unsmoothed polylines.。If no pen style is defined, the previous style is used.

笔记：提示：MapInfo MIF supports a special type for two point lines. The FME transparently converts such MIF线进入折线，既读取MIF文件，也​​可以写它。

The table below lists the special FME attribute names used to control the MIF polyline settings.

MIF region features specify area (polygonal) features. The areas that make up a single feature may or may not be disjoint, and may contain polygons that have holes. Each region has a pen style associated with it to control the color, width, and pen pattern used when its boundary is drawn. In addition, a region may set its brush pattern, foreground, and background color to control how its enclosed area will be filled. If no pen or brush style is defined for a region entity, the previous style is used. The following table lists the special FME attribute names used to control the MIF region settings.

MIF text features are used to specify annotation information. Each text feature can have its font, color, spacing, justification, and rotation angle set independently. The following table lists the special FME attribute names used to control the MIF text settings.

提示：提示：除非指定字体名称，否则不会使用字体颜色和样式设置。

MIF椭圆特征是点特征，只有单个坐标。这一点用作椭圆的中心。附加属性指定椭圆的主轴和次轴。MIF椭圆目前不支持旋转。为了与其他系统的兼容性，MIF读取器始终返回0的旋转0.如果向编写器指定旋转，则椭圆将变为区域，矢量化，并按指定的量旋转。

提示：提示：The primary ellipse axis is不是necessarily the longest axis, but rather the one on the x axis.

In addition to the attributes below, ellipses also make use of the brush and pen attributes as defined bymif_region.。

MIF弧功能是用于指定椭圆弧的线性功能。因此，特征定义mif_arc.类似于具有两个额外角度的椭圆定义来控制绘制椭圆边界的一部分。MIF弧当前不支持旋转。为了与其他系统的兼容性，MIF读取器始终返回0的旋转。另外，如果将旋转指定给写入器，则电弧变成折线，矢量化，并按指定的量旋转。

提示：ArcStroker变压器可用于将弧形转换为Linestring。这对于在不直接支持它们的系统中存储弧。

除了下面的属性外，弧还会使用定义的笔属性mif_polyline.。

MIF rectangle objects are represented in the FME as closed polygons. When a MIF rectangle is read, it is turned into a closed polygon feature. When a MIF rectangle is written, the minimum bounding rectangle of the feature is taken and used as the four corners of the rectangle. MIF rectangles take the same additional attributes as MIF regions to specify their brush and pen.

MIF圆角矩形对象在FME中表示为封闭的多边形。当读取MIF圆角矩形时，它变成了封闭的多边形特征，并且拐角矢量化以保持矩形的预期形状。舍入半径也作为属性存储。

MIF圆角矩形时,二分音符um bounding rectangle of the feature is taken and used as the four corners of the rectangle, and the rounding diameter is taken from an attribute of the feature. MIF rounded rectangles take the same additional attributes as MIF regions to specify their brush and pen.

MIF集合被定义为其他特征类型的组合。这表示为由其他特征类型组成的非均匀聚集体。

To create MapInfo collections using FME, set themif_type.归因于mif_collection.on the feature destined for the MIF dataset. It is important that the feature to be saved as a collection is an aggregate feature.
