The Curvemeister 3 Reference

Image Preview Window Options

This section discusses the options that affect the display and behavior of the image preview window, also called the window.

Image window options are accessed by clicking the icon located at the top of both the curve and image window. Most, but not all, of these options may also be changed using commands from the image window's right-click menu. Unlike the Curve options, you must click Apply to see the effects of a new option setting. Click Cancel if you decide to back out of any changes.

Hue Clock controls the options affecting the appearance of the data in new sample panes. No Hue Clock specifies that no hue clock is displayed, only numeric values. Clock and Text specifies that both the hue clock and text values will be displayed. Hue Clock Only specifies that only the hue clock will be visible Mini Hue Clock causes a smaller version of the hue clock to be displayed. Hue Clock Uses Lab specifies that the Hue Clock will base its hue and saturation calculation on the Lab space, instead of the HSB space. The resulting hue angles are slightly different than the standard HSB values, but this option has advantages in situations where stability is required in very dark or light colors. Sample Display controls what values will be displayed in new sample panes, and the number of decimal places that will be displayed. These options also somewhat affect the creation of new pins. Decimal places controls the number of decimal places that will be displayed, Show Before/After causes the display of channel values before and after the curve operation. Show Std. Deviation causes the standard deviation of each channel to be displayed. This option is only in effect if Curvemeister's working space matches the color space of the original image. Show Delta E causes a number related to the color difference between a pin and the image sample value to be displayed. Create New Samples With changes the default settings for new samples, as well as the initial settings of the "roving" sample display in the upper right corner of the curve window. Note: to change existing samples, select the sample points you want to change, then use the right click menu in the preview window. Sample Size specifies the default sample size in pixels of the square area that is averaged to calculate the sample value. You may use this popup list to specify any of several sizes, or set the size to an unlimited custom value. This sample size has no effect on the custom sample size, although it is very similar in function. Color Space specifies the default color space used for new samples, and for the initial value of the roving sample display. Color Value Display is a global setting that controls the display format of the data in the sample pane. Advanced options are seldom used options that are provided for special situations. Use Offscreen Buffer specifies that an offscreen memory buffer should be used for flicker free display of the image. Since the amount of memory is relatively small, this option should be unchecked only for systems that are low on memory. Update During Drag specifies that dragging a constrained sample, such as a shadow, highlight, neutral, or pin, will update the preview image in real time. This option is a carry-over from the days of slower computers. Support Soft Proof specifies that curvemeister perform an extra color conversion during preview. to support with Photoshop's Soft Proof feature. HiBit Sample conv specifies that Curvemeister use 16 bit color conversions in its internal calculations for Hue clock and Pinning, even for 8 bit images. Since 8 bit his may give a more accurate result than the corresponding 8 bit color conversion. Shadow and Highlight Targets are the shadow and highlight values that are used, by default, in the image window for setting shadow and highlight values via the right click menu. Note: alternatively, you may define shadow and highlight pins, and drag them onto the image to set shadow and highlight values. . Shadow designates a default shadow value. It may be specified in RGB, CMYK, wgCMYK, Lab, of HSB. Use % to denote ink percentages. This shadow value is used for calculating the threshold image in threshold mode, and when a shadow point is being dragged. Highlight is similar to the shadow point, except that it denotes the default highlight value.
