(o_0 ): Powershell SVG Maker

I was going to sit around ill at hone and make an SVG one little square at a time in Inkscape of this image I use...

However, after 4 dots I got bored.

I know that an SVG file is an XML based descriptor of images and shapes and know that I can use minimal information to make a test file that is similar to the following 2x2 block...

So... by grabbing the image, and looping through the pixels we can create all the rects we need. we can even keep the original color of the pixels. This routine also has a scaling factor in it.

$FilePath = 'LesleyatHonda.12.Dither.Part.White.png'
$Image =  [System.Drawing.Image]::FromFile($filePath)

# Simple dirty UTF-8 outfile << THIS IS MPORTANT!!
$OutFilePath = 'LesleyatHonda.svg'
$SVGScale = 10

'<?xml version="1.0" encoding="UTF-8"?>' | Out-File $OutFilePath -Encoding utf8
'<svg version="1.1" baseProfile="full" width="'+($Image.Width*$SVGScale)+'" height="'+($Image.Width*$SVGScale)+'" xmlns="http://www.w3.org/2000/svg">' | Out-File $OutFilePath -Append -Encoding utf8

For($ypos=0;$ypos -lt $Image.Height;$ypos++){
    For($xpos=0;$xpos -lt $Image.Width;$xpos++){
        $Pixel = $Image.GetPixel($xpos,$ypos)
        '<rect fill="#'+($Pixel.Name.substring(2,6))+'" x="'+($xpos*$SVGScale)+'" y="'+($ypos*$SVGScale)+'" width="'+$SVGScale+'" height="'+$SVGScale+'"/>' | Out-File $OutFilePath -Append -Encoding utf8
    }
};

'</svg>' | Out-File $OutFilePath -Append -Encoding utf8
