About Picture Effects...

Picture effects are effects that can be used on, or with, selected Pictures objects inside PageStream or pictures loaded in BME.

SectionBrightness
This effect brightens and darkens pixels. You can set the brightness adjustment from -100 to 100%.

This effect cannot be used on black & white or palette pictures.

SectionContrast
This effect increases and decreases the differences between colors. You can set the contrast adjustment from -100 to 100%.

This effect cannot be used on black & white or palette pictures.

SectionEmboss
This effect creates a three dimensional effect by emphasizing edges. There are no options.

This effect cannot be used on black & white or palette pictures.

SectionNegative
This effect inverts the colors of pixels to create a negative. This is most useful for grayscale and black & white pictures.

This effect cannot be used on palette pictures.

SectionPixelize
This effect breaks a picture into blocks of pixels to make the picture jaggier. You can set the size of the blocks (cells) and how the color for each is chosen.

Average uses the average of all colors in the cell. Center uses the center pixel's color. Minimum and maximum uses the min and max color values in the cell. Random selects a color from any pixel in the cell and Upper Left uses the top left pixel's color.

SectionReduce Noise
This effect removes isolated clusters of pixels below a certain size. This is useful when cleaning up scanned images and when preparing a picture for tracing. You can set the noise size below which pixels should be replaced with the background color. Be careful not to set the noise value too high, or you will eliminate important parts of your picture.

This effect cannot be used on black & white or palette pictures.

SectionSharpen
This effect improves the "focus" of a picture. Use it to correct blurry pictures.

This effect cannot be used on Black & White or palette pictures.

SectionTiles
This effect tiles thumnails of the picture or selection in the picture or selection. You can set the number of horizontal and vertical tiles.

SectionTrace
This effect traces the edges of a picture and creates a drawing that matches the picture. Drawings are made up of points connecting line and curve segments. They usually lack the realism of a photograph, but can be scaled without loss of detail and are smaller and faster.

This effect is a basic autotracer. The resulting drawing is saved in IFF DR2D format: a structured drawing format that can be imported into PageStream.

In the Pro version of PageStream, this is found in the Edit Palette when a picture object is selected. Select the FX at the right side of the Edit Palette, which brings up a "Select Module ..." requester with a drop down menu of options.
I'm not sure which formats are palette based, but I would guess .png is. Possibly .jpg is not palette based.
Be aware that there seems to be no "undo" presently.
