IMImageQ16MBS.Close

There is no need to call this method except you want to free all resources used by this object now without waiting for Xojo to do it for you.

IMImageQ16MBS.ClutImage(clutImage as IMImageQ16MBS) as Boolean

The values are extracted along a diagonal of the CLUT image so either a horizontal or vertial gradient image can be used.

Typically this is used to either re-color a gray-scale image according to a color gradient in the CLUT image, or to perform a freeform histogram (level) adjustment according to the (typically gray-scale) gradient in the CLUT image.

When the 'channel' mask includes the matte/alpha transparency channel but one image has no such channel it is assumed that that image is a simple gray-scale image that will effect the alpha channel values, either for gray-scale coloring (with transparent or semi-transparent colors), or a histogram adjustment of existing alpha channel values. If both images have matte channels, direct and normal indexing is applied, which is rarely used.

ClutImage: the color lookup table image for replacement color values.

Returns true on success or false on failure.

IMImageQ16MBS.ClutImageChannel(ChannelType as Integer, clutImage as IMImageQ16MBS) as Boolean

IMImageQ16MBS.CoalesceImages as IMImageQ16MBS

GIF, MIFF, and MNG animation sequences typically start with an image background and each subsequent image varies in size and offset. CoalesceImages() returns a new sequence where each image in the sequence is the same size as the first and composited with the next image in the sequence.

Returns nil on any error.
Sets the last exception property.

IMImageQ16MBS.Colorize(opacity as string, PenColorRed as Integer, PenColorGreen as Integer, PenColorBlue as Integer, PenColorOpacity as Integer) as IMImageQ16MBS

The colorization is controlled with the pen color and the opacity levels.

opacity: A character string indicating the level of opacity as a percentage (0-100).
PenColorRed, PenColorGreen, PenColorBlue and PenColorOpacity define the pen color used.

Returns nil on any error.
Sets the last exception property.

IMImageQ16MBS.Combine(channel as Integer) as IMImageQ16MBS

The grayscale value of the pixels of each image in the sequence is assigned in order to the specified channels of the combined image. The typical ordering would be image 1 => Red, 2 => Green, 3 => Blue, etc.

The lastexception property is set.

IMImageQ16MBS.CompareImageLayers(ImageLayerMethod as Integer) as IMImageQ16MBS

Images do NOT have to be the same size, though it is best that all the images are 'coalesced' (images are all the same size, on a flattened canvas, so as to represent exactly how an specific frame should look).

No GIF dispose methods are applied, so GIF animations must be coalesced before applying this image operator to find differences to them.

ImageLayerMethod:
the layers type to compare images with. Must be one of... CompareAnyLayer, CompareClearLayer, CompareOverlayLayer.

Can raise an exception.

IMImageQ16MBS.Composite(ComposeOperator as Integer, Image as IMImageQ16MBS, x as Integer, y as Integer)

compose: Specifies an image composite operator.
Image: The second image.
x: An integer that specifies the column offset of the composited image.
y: An integer that specifies the row offset of the composited image.

No error code and exception!

IMImageQ16MBS.ContrastImage(sharpen as boolean) as Boolean

Returns true on success or false on failure.
Set sharpen to true to increase the image contrast otherwise the contrast is reduced.
