Description

Examples

Compose a picture on second:

# load images...
Set Variable [ $Image1 ; Value: MBS( "GMImage.NewFromFile"; "/Users/cs/Pictures/IMG_3625.jpg") ]
Set Variable [ $Image2 ; Value: MBS( "GMImage.NewFromFile"; "/Users/cs/Pictures/mond.jpg") ]
# put first on second
Set Variable [ $r ; Value: MBS( "GMImage.CompositeXY"; $Image2; $Image1; 500; 200) ]
# and save to file
Set Variable [ $r ; Value: MBS( "GMImage.WriteToFile"; $Image2; "/Users/cs/Pictures/output.jpg") ]
# free memory
Set Variable [ $r ; Value: MBS( "GMImage.Release"; $Image1) ]
Set Variable [ $r ; Value: MBS( "GMImage.Release"; $Image2) ]

Compose transparent picture on top of white background:

# Load from container
Set Variable [ $BigImageRef ; Value: MBS("GMImage.NewFromContainer"; Test::BigImage) ]
# make new picture
Set Variable [ $NewImageRef ; Value: MBS("GMImage.New"; MBS("GMImage.GetWidth"; $BigImageRef) & "x" & MBS("GMImage.GetHeight"; $BigImageRef); "white") ]
# and compose
Set Variable [ $r ; Value: MBS( "GMImage.CompositeXY"; $NewImageRef; $BigImageRef; 0; 0; 1 /* over */) ]
# Store output and release the image
Set Field [ Test::Result ; MBS( "GMImage.WriteToJPEGContainer"; $NewImageRef ) ]
Set Variable [ $Error ; Value: MBS("GMImage.Free";$BigImageRef) ]
Set Variable [ $Error ; Value: MBS("GMImage.Free";$NewImageRef) ]
