Major New Features in PWP 7.0

Multi-core support for significantly higher performance

Nearly all transformations are now multi-tasked, so that they use all the cores your system provides. Generally this increases performance by a factor equal to the number of cores available.

Related changes: A new Number of Threads setting has been added to File/Preferences. It allows you set the maximum number of threads that will be launched for multi-tasked operations. You can set this number to the number of cores on the system, twice the number of cores, or to one. The latter setting disables multi-tasking. Also workflows now defaults a single background process. Since nearly all transformations are multi-tasked, there is rarely an advantage to launching multiple processes.

Frame and Mat Transformation

This new transformation lets you explore many framing and mat options and arrive at a design which displays your image to its best advantage. You can experiment with single and double mat designs and with different colors and textures and different framing options. For example, you can choose among a variety of frame profiles, varying width and color to suit your image. More intricate frames, like the one in the example at right, are also available. These are automatically constructed by the transformation from images of frame sections.

Once you have come up with the best design, you can use it in a variety of ways:

  • You can use your design to cut the mats and make the frame. The transformation can print out the dimensions and other parameters of your design.

  • You can print our your image together with the textured mats in your chosen colors and place them into a frame.

  • You can output the matted and framed image, save it as an image file, post it on a web site, etc. See Mat Notes for details.

The transformation is under Transformation/Special Effects.

Wave Transformation for Making Patterns

The Wave transformation lets you create patterns composed of interlocking shapes and color transitions. The transformation creates a single repeat of the pattern. The pattern can then be tiled to produce as large an image as required, like the example shown at right. These patterns can be used to create interesting borders, mats and backgrounds.

The transformation is located under the new category Pattern, Texture, Tile in the Transformation menu. See Wave Notes for details.

Watercolor Transformation

water color effect

The Watercolor transformation gives images the look of a watercolor painting by simulating brush strokes and darkening edges to simulate the way watercolors pool near brush boundaries. You can control the look by controlling the amount of blurring within the 'brush stroke' and the sharpening and darkening of stroke boundaries. See Watercolor Notes for details.

The transformation can be found under Transformation/Special Effects.

Defringe Transformation

Defringe before and after images

The Defringe transformation removes or reduces purple fringe artifacts which can be frequently seen near over-exposed pixels. Fringing can often be seen around backlit detail such as tree branches against a bright sky or when the image has specular highlights like the railroad tracks in the before and after images shown above. Cleaning up fringing, even when it is not particularly noticeable, produces a cleaner, crisper image.

Purple fringing is sometimes confused with chromatic aberration. However it has a different cause and structure and so requires a customized tool. See Defringe Notes for details on how to recognize the difference between these types of fringing and select the right correction tool.

The transformation can be found under Transformation/Color.

Calibrating Cameras and Scanners

The Build Camera/Scanner profle function creates ICC color profiles of cameras and scanners. This is essentially the same function as Profile Mechanic - Scanner, previously available as a separate application. The function creates profiles from images of calibration targets created by the camera or scanner to be calibrated. The profile can then be used within Picture Window to accurately display the image. See Create Camera-Scanner Profile Notes for details.

The function can be found under File/Build Scanner-Camera Profile.

Bad Pixels Transformation

This transformation detects bad pixels in a camera sensor and constructs a bad pixel file that you can use in the Raw dialog to fill in the damaged pixels. To use the transformation, you make two test exposures and then use the transformation to analyze them and create the bad pixel file.

The transformation is located under Transformation/Special Effects.

Contour Transformation

The Contour transformation analyzes an image and creates contour lines along brightness boundaries. You can control the the number of brightness contours created and the color of the contour lines. The lines can be superimposed over the image or the image itself can be supressed as in the example at right.

The transformation is located under Transformation/Special Effects.

Monocolor Transformation

The Monocolor transformation creates an image which uses black plus a single other color. The second color may be red, green, or blue. The transformation can be used through a mask. The background may be deemphasized, for instance by running the transformation through a mask of the background.

The transformation is located under Transformation/Special Effeects

Transformation Enhancements

Blur Transformation
Two new methods have been added to blur -- Precision Gaussian and a chroma-only Precision Gaussian. The full precision gaussian method reduces halo effects when masks are used. It gives a cleaner look and is now the recommended method for selectively blurring backgounds. An added bonus is that precision gaussian creates what many feel is an ideal bokeh.

The chroma-only methods is useful for reducing noise in shadow areas. It selectively smooths color 'speckling' which is otherwise the most apparent form of noise in areas of low light.

The two precision gaussian methods require considerably more calculation and are thus slower than other blur methods. You should continue to use the other blur methods when the special advantages of the new methods are not applicable. See Precision Gaussian Notes for details.

Levels and Color Transformation:

A slider to control Contrast has been added to the transformation's existing midtone brightness, dynamic range, color balance and saturation controls. Thus the transformation offers a quick way to make the most commonly used image adjustments.

Special Effects/Conformal Mapping Transformation
The Joukowsky and Inverse Joukowsky transformations have been added to Conformal Mapping. The Joukowsky transformation creates fluid distortions of an image. Since it behaves differently in each of the four quadrants of the x-y plane, applying it to a 2x2 tile of an image will quickly give you four different distortions to choose from for each setting of the controls. An example is shown below.

Examples of Joukowsky transform.

Extract Jpeg from Raw Widget

A new widget allow you to extract the jpeg image encoded into most raw files. This image is adjusted according to the camera manufacturer's specifications. It provides the simplest and fastest way to extract an image from a raw file. The Extract widget must be the first widget in a workflow. It is bypassed for non-raw images.

Other Changes

Color Management Settings:

Color Management now includes a new option for monitor profile. PWP can now set the monitor profile from the official system monitor profile setting (as shown in the Windows Display control panel - Advanced settings - Color Management tab). This is useful in cases where, for example, monitor calibration software updates the windows profile setting and thus update PWP at the same time. The previous option of specifying monitor color profile explicitly is available as before and is the default. Thus PWP operation remains the same unless you specifically change it.

Font Size Control

The size of the font used in most of the displays can now be set in File/Preferences. This allows you to set it according to the size and resolution of your monitor and your preferences.


When files are converted from 8 bit to 16 bit formats, the new lower eight bits are now assigned random values instead of being set to zero. This will result in smoother-looking images and and gradients.


Texture can now create color textures in addition to b+w ones.

Change Log

PWP 7.0.9 (29 May 2013)

New Documentation

  • This release updates the Picture Window manual with all the new PWP 7 features. Documentation, which changes less frequently than Picture Window itself, will continue to be available as a separate download. The download also includes white papers (including new ones introduced in PWP 7) and sample images. It can be installed using the documentation link above.

Bug Fixes. Most of the reported bugs have been fixed. In particular these include:

  • Create Profile bug.
  • Mat and Frame dialog display bug.
  • Drop Shadow dialog display bug.
  • Mask Paint tool operation.
  • Advanced Sharpen Cancel bug.
  • Ruler display problem in Layout.
  • Refinement in preview display for Crop/Add Border.
  • Removal of File/Associations dialog because the underlying API is no longer supported by Windows.
  • File Comments bug in History.

PWP 7.0.8 (25 April 2013)

New features this release

  • Mat and Frame Transformation: The image panel now shows two sets of width and height dimensions. Target width and height refer to the dimensions of the item on which size is based. This can be outside or inside frame size, mat opening size or image sizes. Image width and height refers to the size of the image and is the same or different from the target width/height depending on what the size is based on.

  • BrowseInfo File: The thumbnail browser now uses universal time rather than local time to determine if cached thumbnails need to be refreshed. This should eliminate unnecessary refreshing of the caches twice a year when the clock is reset between standard and daylight savings time. This change required changing the file format and renaming the browse info file to pwp.browseinfo. (The older pw60.browseinfo file is currently left in place to accomodate those using both the PWP v6 and PWP v7 beta. Once the beta version is officially released, older browseinfo files will be automatically deleted.)

  • Extract Channel: The history diplay now lists the channel extracted by Extract Channel in the image caption. To display the window with a particular channel, simply double click the item in the history display.

Bug Fixes

  • Most of the reported bugs have been fixed. In particular these include, a bug in Advanced Sharpen widget, the Levels and Color transformation, font problems in the suub-dialogs of the Calendar transformation and others. Please see the PWP 7 Beta forum on the message board for details. Thanks to the beta testers who brought these to our attention.

PWP 7.0.7 (03 April 2013)

New features this release

  • Advanced Sharpen Widget: The Advanced Sharpen transformation is now available within workflow.

  • Window List: A list of all open windows now allows you to close windows and to display image properties by right-clicking on items in the list.

  • File Comment Editing: Editing of Exif image create dates and IPTC name and caption fields has been added to the the Edit Comments dialog. This allows adding create dates to images, like scanned images, which otherwise lack them. The dialog accepts partial dates such as only year or only year and month, when that is all that is known. Also, the Edit Comments dialog can now be accessd from File Save As, making it easier to add comments when saving an image.

Bug Fixes

  • Most of the reported bugs have been fixed. In particular these include, a bug where jpeg files were improperly saved as tiffs, a crash bug in the mask dialog and a bug in the display of the main toolbar. Please see the PWP 7 Beta forum on the message board for details. Thanks to the beta testers who brought these to our attention.

PWP 7.0.6 (18 Mar 2013)

New features this release

  • New Defringe Transformation: This new transformation effectively neutralizes purple fringing. The purple fringes are frequently confused with chromatic aberration. However they are actually artifacts produced near over-exposed highlights. See Defringe%20Transformation%20Notes for tips on how to recognize and neutralize this artifact. (This white paper is included in the PWP7 New Features Doc.zip donload above.) The transformation is invoked from the Transformation/Color menu. A toolbar button

  • Window List: A list of all open windows is now availalble from the Windo menu. The list includes thumbnails for image and raw dialog windows and can be used to bring any window to the top.

  • Setting PWP font size: The font size used in many PWP dialogs and displays can now be adjusted. The adjustment is relative to the current Windows font size as selected in the Appearance and Personalization/Display section of the Control Panel. The adjustment is made under File/Preferences. (Note that some PWP displays use the Windows fonts directly and so are not affected by this control.)

  • Menu rearrangement: The transformtaion menu and its sub-menus are now alphabetized, for easier access to functions. Other small changes include the renaming of the Change Color Profile item to Profile, Add Noise to White Noise. Filter has been moved under Color; Tile and Kaliedoscope are now under Special Effects; Mat and Frame are now in the top-level Transformation menu, appearing after Layout.

Other Changes

  • Reset, Load and Save As functions have been added to the Posterize and Chromatic Aberration transformations. Chromatic Aberration also gains a new button that toggles the preview to show the image before and after the applicaion of CA, to make exact adjustment easier.

  • Image Properties: The standard image properties display is now available from the Windows menu as well as from the browser and by right-clicking on an image.

  • Watercolor transformation now has a new Median Threshold slider which controls how much fine detail is preserved.

  • Blur transformation's Precise Blur functions now displays an additional mask window for use when a mask, to selectively blur the background for instance. Please see Precision Gaussian Notes for details on using it.

  • Blink has a new cycle control which allows an uninterrupted number of 'blinks' before the control window is redisplayed.

  • Browse now issues an error message when the deletion of an image cannot be completed. This usually happens when an attempt is made to delete an image that is write-protected or on read-only media.

  • Bug Fixes: Most of the reported bugs have been fixed. Please see the PWP 7 Beta forum on the message board for details. Thanks to the beta testers who brought these to our attention.

PWP 7.0.5 (24 Feb 2013)

Changes in this release:

  • Change Color Profile bug related to using the default Windows color engine has been corrected.

  • Find Bad Pixels The zero y coordinate has been changed to the top left corner match that used by the raw converter. Sensitivity for detecting bad pixels has been increased.

  • Dialog Display Problems: Cutting off of some transformation dialogs under certain combinations of display font settings has been fixed.

  • Transformation Cancel Problem: An intermittent problem with the operation of the Progress Indicator Cancel button has been fixed.

PWP 7.0.4 (16 Feb 2013)

Changes in this release:

  • Build Camera/Scanner Profle function has been added. It creates ICC color profiles of cameras and scanners and is essentially the same function as Profile Mechanic - Scanner, previously available as a separate application. Te camera orhe function creates profiles from images of calibration targets created by the camera or scanner to be calibrated. The profile can then be used within Picture Window to accurately display the image. See Create Camera-Scanner Profile Notes for details.

  • Monocolor transformation has been added. It creates an image which uses black plus a single other color. The second color may be red, green, or blue.

  • Picture Window now runs under Windows XP.

  • A bug in displaying the Find Bad Pixels transformation Help page using the F1 key has been fixed.

  • A bug in which cancelling the Mask dialog caused a crash has been fixed.

PWP 7.0.3 (8 Feb 2013)

Original release.
