css - Crop and scale an image in SVG -

-

I have a SVG element in my HTML that contains two external files, another SVG and a bitmap. 

  & lt; Svg xmlns = "http://www.w3.org/2000/svg" xmlns: xlink = "http://www.w3.org/1999/xlink" width = "1024" height = "768" & gt; & Lt; Image xlink: href = "bitmap.png" /> & Lt; Image xlink: href = "outline.svg" /> & Lt; / Svg & gt;

My purpose is that I can swap any other (any size) bitmap and get a bitmap:

  1. Scale the width down (
  2. Close the bottom part of the bitmap

I have interpreted the bitmap image using the view box on the clippath, sub-SVG elements, And I can not nail the problem. I try to do it without javascript

Any thoughts?

  & lt; svg xmlns = "http://www.w3.org/2000/svg" xmlns: xlink = "http: // www .w3.org / 1999 / xlink "width =" 200 "height =" 45 "> Image ID =" IMG "x =" 0 "y =" 0 "width =" 100% "height =" 100% "xlink: href =" http://cdn.sstatic.net/stackexchange/img/logos/so/so-logo.png "preserveAspectRatio =" xMinYMin piece "/> & lt; / svg & gt;

How to access user directory in lazarus? -

After I am trying to open file changelog.txt and it does not matter if I open it Need to have the user open it though it is always located in the ~ / directory. Enter the file here.

Any idea how can I get the username that started the program? ! Thanks Edit1: I have tried this, but this also includes a new line: RunCommand ('/ bin / bash', ['- - C ',' Whoami '], users); This is normal. The concept of "~" is an shell level and thus requires a separate shell elev...
