PictureMBS.TransferFilter(dest as PictureMBS, gray() as Integer, alpha() as Integer) as PictureMBS

if dest is nil, the picture factory is used to create a new picture.
On success dest or the new picture is returned.
If dest is not nil, it must match the size of the original picture.

The arrays for gray and alpha must have 256 entries starting with index 0.
For RGB pictures the gray array is used for all three channels.
If the picture has no alpha channel, the alpha parameter is ignored.

Returns nil on any error.

PictureMBS.TransferFilter(dest as PictureMBS, red() as Integer, green() as Integer, blue() as Integer) as PictureMBS

dim l as Picture = LogoMBS(500)
dim p as new PictureMBS(l)

dim red(256) as Integer

for i as Integer = 0 to 255
  red(i)=i

PictureMBS.Unmultiply

Pictures with alpha channel must be multiplied, while pictures with mask have the alpha unmultiplied and inverse in the mask.

• Unmultiply(x as integer, y as integer, width as integer, height as integer)

Some examples using this method:

• /Images/LargePicture/Picture Multiply

PictureMBS.Unmultiply(x as integer, y as integer, width as integer, height as integer)

Pictures with alpha channel must be multiplied, while pictures with mask have the alpha unmultiplied and inverse in the mask.

PictureMBS.UnsharpFilter(origpixels as PictureMBS, Amount as Double, Threshold as Integer) as boolean

You may want to run the BoxBlur filter first before using the unsharp filter.

if dest is nil, the picture factory is used to create a new picture.
On success dest or the new picture is returned.
If dest is not nil, it must match the size of the original picture.

Returns nil on any error.

Works with Gray, RGB and CMYK pictures and supports alpha channel.

PictureMBS.VMirror

// get some picture
dim l as Picture = LogoMBS(500)
// create new image
dim p as new PictureMBS(l)
// mirror
p.VMirror
// show in window
window1.Backdrop = p.CopyPicture

Works with Gray, RGB and CMYK pictures and supports alpha channel.

Some examples using this method:

• /Images/LargePicture/PictureMBS mirror and rotate
• /Images/LargePicture/Tiff Load and Save

PictureMBS.YellowChannel as PictureMBS

Returns nil if this channel does not exist.
No copy is made of the actual pixel data. Modifying the channel picture will modify the original picture.
Use this function to access the pixels of the channel directly.
The resulting PictureMBS object is a grayscale picture.
