dim g as new GMImageMBS( new GMGeometryMBS(p.Width, p.Height), new GMColorGrayMBS(1.0))

g.type = g.TrueColorMatteType
g.matte = True
g.magick = "BMP"

g.SetPictureMask(p.mask.invertMBS, 0, 0)

f = SpecialFolder.Desktop.Child("test.bmp")
g.write(f)

GMImageMBS.setPixels(x as Integer, y as Integer, columns as Integer, rows as Integer) as Ptr

Type Topic Plugin Version macOS Windows Linux iOS Targets
method GraphicsMagick MBS GraphicsMagick Plugin 16.4 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All
Allocates a pixel cache region to store image pixels as defined by the region rectangle.
Example
dim f as FolderItem = SpecialFolder.Desktop.Child("test.jpg")
dim g as new GMImageMBS(f)

// get pointer to some pixels to write
dim x as ptr = g.setPixels(0, 0, 100, 100)

// draw a red line to the pixel buffer
dim o as Integer
for i as Integer = 0 to 99
o = 100 * i + i
x.UInt32(o * 4) = &hFFFF0000
next

// write back
g.syncPixels

// show
me.Backdrop = g.CopyPicture

This area is subsequently transferred from the pixel cache to the image via syncPixels.

GMImageMBS.shear(xShearAngle as Double, yShearAngle as Double)

Type Topic Plugin Version macOS Windows Linux iOS Targets
method GraphicsMagick MBS GraphicsMagick Plugin 9.3 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All

Example
dim p as Picture = LogoMBS(500)
dim image as new GMImageMBS(p)

image.shear(10,20)

Backdrop=image.CopyPicture

Shearing slides one edge of an image along the X or Y axis, creating a parallelogram. An X direction shear slides an edge along the X axis, while a Y direction shear slides an edge along the Y axis. The amount of the shear is controlled by a shear angle. For X direction shears, x degrees is measured relative to the Y axis, and similarly, for Y direction shears y degrees is measured relative to the X axis. Empty triangles left over from shearing the image are filled with the color defined as borderColor.
