You can adjust the density and color of each stop individually, as well as add and delete stops. For inspiration on color choices for your heatmap, try Color Brewer. opacity: Controls the global opacity of the heatmap layer. radius: Sets the radius for each point in pixels. As the ...
对opts.inTargetDensity进行了赋值,该值为当前设备的densityDpi值,所以说在decodeResourceStream方法中主要做了两件事: 1.对opts.inDensity赋值,没有则赋默认值160 2.对opts.inTargetDensity赋值,没有则赋当前设备的densityDpi值 之后参数将传入decodeStream方法,该方法中在调用native方法进行解析Bitmap后会调用这个方法...

• 「inTargetDensity」代表的是「Bitmap将绘制到的目标的像素密度」,通常就是指屏幕的像素密度。 这两个参数起什么作用呢,让我们继续往下看: publicstaticBitmapdecodeStream(InputStreamis, Rect outPadding, Options opts){ ··· if(isinstanceof AssetManager.AssetInputStream) { ...
powerOfTwoWidth, powerOfTwoHeight, targetWidth, targetHeight); 最后一步比较难理解,其实这样做实际就相当于把缩放因子小数化分数,比如0.5=1/2,随后把1和2分别设置到inTargetDensity和inDensity。 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { ...
Selecting this option for maps or layouts that contain vector layers with a high density of vertices can reduce the output file size. When exporting to PDF and this option is set to True, you cannot view PDF layers in the output. (默认值为 False) Boolean SVG 格式是一种基于 XML 的文件...

All places other than large cities will have a scalerank of null. Localrank The localrank field can be used to adjust the label density by showing fewer labels. It is a whole number greater than 0 calculated by grouping places into a 128 pixel grid at each zoom level, then assigning...
