SVG Shapes


SVG has some predefined shape elements that can be used by developers:



  • Rectangle <rect>

  • Circle <circle>

  • Ellipse <ellipse>

  • Line <line>

  • Polyline <polyline>

  • Polygon <polygon>

  • Path <path>


The following chapters will explain each element, starting with the rect element.



SVG Rectangle - <rect>


Example 1


The <rect> element is used to create a rectangle and variations of a rectangle shape:



Sorry, your browser does not support inline SVG.

Here is the SVG code:



Example



<svg width="400" height="110">
 
<rect width="300" height="100"
style="fill:rgb(0,0,255);stroke-width:3;stroke:rgb(0,0,0)" />
</svg>

Try it Yourself »

Code explanation:



  • The width and height attributes of the <rect> element define the height and
    the width of the rectangle

  • The style attribute is used to define CSS properties for the rectangle

  • The CSS fill property defines the fill color of the rectangle

  • The CSS stroke-width property defines the width of the border of the rectangle

  • The CSS stroke property defines the color of the border of the rectangle








googletag.cmd.push(function() { googletag.display('div-gpt-ad-1493883843099-0'); });





Example 2


Let's look at another example that contains some new attributes:



Sorry, your browser does not support inline SVG.

Here is the SVG code:



Example



<svg width="400" height="180">
 
<rect x="50" y="20" width="150" height="150"
 
style="fill:blue;stroke:pink;stroke-width:5;fill-opacity:0.1;stroke-opacity:0.9" />
</svg>

Try it Yourself »

Code explanation:



  • The x attribute defines the left position of the rectangle (e.g. x="50"
    places the rectangle 50 px from the left margin)

  • The y attribute defines the top position of the rectangle (e.g. y="20"
    places the rectangle 20 px from the top margin)

  • The CSS fill-opacity property defines the opacity of the fill color (legal range: 0 to 1)

  • The CSS stroke-opacity property defines the opacity of the stroke color (legal range: 0 to 1)



Example 3


Define the opacity for the whole element:



Sorry, your browser does not support inline SVG.

Here is the SVG code:



Example



<svg width="400" height="180">
 
<rect x="50" y="20" width="150" height="150"
 
style="fill:blue;stroke:pink;stroke-width:5;opacity:0.5" />
</svg>

Try it Yourself »

Code explanation:



  • The CSS opacity property defines the opacity value for the whole element (legal range: 0 to 1)



Example 4


Last example, create a rectangle with rounded corners:



Sorry, your browser does not support inline SVG.

Here is the SVG code:



Example



<svg width="400" height="180">
 
<rect x="50" y="20" rx="20" ry="20" width="150"
height="150"
  style="fill:red;stroke:black;stroke-width:5;opacity:0.5" />
</svg>

Try it Yourself »

Code explanation:



  • The rx and the ry attributes rounds the corners of the rectangle

Clash Royale CLAN TAG #URR8PPP 1 How can I extract a single band from multi-band raster in QGIS? I have an remote sensed image which has 6 bands (including NDVI band), I want to display each band separately, but have no idea how to do. I have seen some questions similar here but none worked for me. The original image (has 6 bands) is: I want to display the band 6 which should be like this: But I tried gdal_translate, and couldn't get the correct result.

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
