Picture.RotateMemoryMBS(angle as double) as Int64

Picture.ScaleImageAndMaskMBS(width as integer, height as integer, AntiAlias as boolean=false, YieldTicks as integer=0) as picture
method, Graphics & Pictures, MBS REALbasic Picture Plugin (PictureScale), class Picture, Not console safe, Plugin version: 7.0, Mac OS X: Works, Windows: Works, Linux x86: Works, Feedback.

Function: Scales the picture to the new size including mask (in case one exists).
Notes:
This is a self made algorithm which produces nice pictures on all platforms.
It is slower than QuickDraw on Mac OS, but nicer than drawpicture on Windows.
Returns nil on low memory or invalid width and height values.

AntiAlias is set to false if width<=self.width or height<=self.height.

If YieldTicks is 0, no time is given to other threads in your application. If it is a value > 0, this time is waited before a thread switch is done. Setting it to 1 will give away control to another thread after 1/60th of a second. We recommend a value of 3 to 5 for a good reponsibility of your application.

Function: Scales the picture to the given size.
Example: 
dim p as Picture

p=LogoMBS(1000)

p=p.ScalingMBS(2, 4000, 4000)

backdrop=p
Notes:
On low memory this function can return nil or the image may look bad. (e.g. all black)

The memory used for the temporary storage is original height * new width * 12 bytes plus some extra.

For scaling with the same size as the picture already has, the scaling is still performed.

Returns nil ony error. (e.g. destwidth=0)

Notes:
Returns true on success and false on failure.
Works only on Mac OS and Windows with 32bit bitmap images.
scrollmask defines whether a mask (if one exists) is also scrolled.

method, Graphics & Pictures, MBS REALbasic Picture Plugin (Picture), class Picture, Plugin version: 6.5, Mac OS X: Works, Windows: Works, Linux x86: Does nothing, Feedback.

Function: Combines calls to ScrollHorizontalMBS and ScrollVerticalMBS.
Notes:
Returns true on success and false on failure.

dim map(-1) as color

for r as integer = 0 to 255
  for g as integer = 0 to 255
    for b as integer = 0 to 255
      // index is r*65536+g*256+b
      
      // we swap colors: r gives g, g gives b, b gives r
      map.Append rgb(g,b,r)
    next
  next
next

Backdrop=p.ThreadedTransformMBS(0, map)
Notes:
Threaded specifies how many threads you want to use:
A negative value disables threading, zero will use one thread for each CPU core and a positive number specifies the thread count.

For each color in the source picture the red, blue and green values are used as index (blue+green*256+blue*65536) in the arrays to get the new color value.

The arrays should have 2^24 entries.
