GM16ImageMBS.texture(texture as GM16ImageMBS)

Type Topic Plugin Version macOS Windows Linux iOS Targets
method GraphicsMagick MBS GraphicsMagick Plugin 14.1 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All
Channel a texture on pixels matching image background color.

GM16ImageMBS.threshold(degree as Double)

Type Topic Plugin Version macOS Windows Linux iOS Targets
method GraphicsMagick MBS GraphicsMagick Plugin 14.1 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All
Threshold image channels (below threshold becomes black, above threshold becomes white).
Example 
Var p as Picture = LogoMBS(500)
Var image as new GM16ImageMBS(p)

image.threshold 127

// convert to RGB so CopyPicture works
image.type = image.TrueColorType
Backdrop=image.CopyPicture

The range of the threshold parameter is 0 to MaxRGB.

GM16ImageMBS.thumbnail(geometry as GM16GeometryMBS)

Type Topic Plugin Version macOS Windows Linux iOS Targets
method GraphicsMagick MBS GraphicsMagick Plugin 16.4 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All
Resize image using several algorithms to make smaller images very quickly.
Example 
Var f as FolderItem = SpecialFolder.Desktop.Child("test.jpg")
Var g as new GM16ImageMBS(f)

// make thumbnail
Var geo as new GM16GeometryMBS(100, 100)
g.thumbnail(geo)

// show
me.Backdrop = g.CopyPicture

GM16ImageMBS.transform(imageGeometry as GM16GeometryMBS)

Type Topic Plugin Version macOS Windows Linux iOS Targets
method GraphicsMagick MBS GraphicsMagick Plugin 14.1 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All
Transform image based on image and crop geometries.

Crop geometry is optional.

Rotation to use when annotating with text or drawing.

GM16ImageMBS.transformScale(tx as Double, ty as Double)

Type Topic Plugin Version macOS Windows Linux iOS Targets
method GraphicsMagick MBS GraphicsMagick Plugin 14.1 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All
Scale to use when annotating with text or drawing.

GM16ImageMBS.transformSkewX(x as Double)

Type Topic Plugin Version macOS Windows Linux iOS Targets
method GraphicsMagick MBS GraphicsMagick Plugin 14.1 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All
Skew to use in X axis when annotating with text or drawing.

GM16ImageMBS.transformSkewY(y as Double)

Type Topic Plugin Version macOS Windows Linux iOS Targets
method GraphicsMagick MBS GraphicsMagick Plugin 14.1 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All
Skew to use in Y axis when annotating with text or drawing.

method GraphicsMagick MBS GraphicsMagick Plugin 14.1 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All
Add matte channel to image, setting pixels matching color to transparent.
Example 
Var p as Picture = LogoMBS(500)
Var image as new GM16ImageMBS(p)

Var c as new GM16ColorMBS("white")
image.transparent(c)

Backdrop=image.CombinePictureWithMask

GM16ImageMBS.trim

Type Topic Plugin Version macOS Windows Linux iOS Targets
method GraphicsMagick MBS GraphicsMagick Plugin 14.1 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All
Trim edges that are the background color from the image.
Example 
Var p as Picture = LogoMBS(500)
// make the logo picture bigger
Var q as Picture = New Picture(700,700,32)

q.Graphics.DrawPicture p,100,100

Var image as new GM16ImageMBS(q)

// now trim the white border away
image.trim

Backdrop=image.CopyPicture

See ColorFuzz property for how far the pixel value can differentiate.
