Convert a SVG image to PNG with alpha channel
You can use GraphicsMagick functions in MBS FileMaker Plugin to convert a SVG to a PNG image with transparency.
To assist there we add a new GMImage.ReadFromContainer function to our plugin. This allows you to create the picture, configure it and then load the picture into the image. When you set background to transparent in a picture with alpha channel, you can preserve the transparency from the SVG. And as you specify a size for the picture and reading it, you can scale the SVG to the size you need:
# Load image from container
Set Variable [ $image ; Value: MBS( "GMImage.New"; "500x500"; "transparent" ) ]
# turn on alpha channel and set background to transparent
Set Variable [ $r ; Value: MBS( "GMImage.SetType"; $image; 7 ) ]
Set Variable [ $r ; Value: MBS( "GMImage.SetBackgroundColor"; $Image; "transparent" ) ]
# Read SVG
Set Variable [ $r ; Value: MBS( "GMImage.ReadFromContainer"; $image; SVG to PNG::InputFile; "500x500"; 0; "SVG" ) ]
# Output to container and release image
Set Field [ SVG to PNG::OutputFile ; MBS( "GMImage.WriteToPNGContainer"; $image; "test.png") ]
Set Variable [ $r ; Value: MBS("GMImage.Free"; $image) ]
