TPRPreviewsParams

Declaration

TPRPreviewsParams = set of (prppDefaultLockPreview, prppShowResetButton, prppHardReset, prppResetSelectedTab, prppSingleEffectOnly);

Description

Configure features of the Image Processing Dialog (displayed by calling DoPreviews).

Value	Description
prppDefaultLockPreview	Enable the "Live Preview" checkbox when the dialog is shown (i.e. preview is automatically updated by default)
prppShowResetButton	Show a "Reset" button, which resets parameters to previous values
prppHardReset	Allow Reset button to reset to default values instead of previous values
prppResetSelectedTab	The Reset button will reset only the selected tab instead of all tabs
prppSingleEffectOnly	Does not allow the user to apply effects from multiple tabs. Only the effect of the active tab is applied. This should be enabled if you are using ApplyPreviews

Example

// Show preview by default
ImageEnView1.Proc.PreviewsParams := ImageEnView1.Proc.PreviewsParams + [ prppDefaultLockPreview ];

// Only allow application of a single effect (only the effect on the active tab)
ImageEnView1.Proc.PreviewsParams := ImageEnView1.Proc.PreviewsParams + [ prppSingleEffectOnly ];
