Monkeybread Xojo plugin - Picture methods

Picture.ThreadedTransformMBS(Threaded as Integer, Map() as color, dest as picture = nil) as picture

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
method	Graphics & Pictures	MBS Picture Plugin	10.0	✅ Yes	✅ Yes	✅ Yes	✅ Yes	All

Performs a transformation to the picture.

Example

dim p as Picture = LogoMBS(500)

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)

Threaded parameter 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.

You can pass destination picture. If dest is not nil and size matches, the plugin reuses the picture object which increases performance as no new picture is created.

Picture.ThreadedTransformMBS(Threaded as Integer, RedMap as memoryblock, GreenMap as memoryblock, BlueMap as memoryblock, dest as picture = nil) as picture

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
method	Graphics & Pictures	MBS Picture Plugin	10.0	✅ Yes	✅ Yes	✅ Yes	✅ Yes	All

Performs a transformation to the picture.

Example

dim p as Picture = LogoMBS(500)

dim red   as MemoryBlock = NewMemoryBlock(256)
dim green as MemoryBlock = NewMemoryBlock(256)
dim blue  as MemoryBlock = NewMemoryBlock(256)

for i as Integer=0 to 255
  red.Byte(i)=i/2
  green.Byte(i)=i/2
  blue.Byte(i)=i/2
next

Backdrop=p.ThreadedTransformMBS(0, red, green, blue)

Threaded parameter 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 in the memoryblocks to get the new color value.

The memoryblocks must have a size of 256 Bytes.
