TImageEnView.TransitionParams
Declaration
TransitionParams: TIETransitionParams;
Description
Specify extra properties to customize
transition effects which are available when loading or changing images.
Properties// Set properties for Word transition
ImageEnView1.TransitionParams.WordTransWord := 'BLAM';
ImageEnView1.TransitionParams.WordTransFontName := 'Arial';
ImageEnView1.TransitionParams.WordTransFontStyle := [fsBold];
// Prepare ImageEnView1 for a transition (e.g. so loading the image will not immediately update the display)
ImageEnView1.PrepareTransition();
// Load the next image
ImageEnView1.IO.LoadFromFile( GetNextImage() );
// Run the transition
ImageEnView1.RunTransition( iettRandomBoxesWithWord, 1000 );
// Display an alternative transition with a pentagonal shape
ImageEnView1.TransitionParams.TransitionShape := iesPentagon;
ImageEnView1.TransitionParams.AlternativeStyle := True;
ImageEnView1.PrepareTransition();
ImageEnView1.IO.LoadFromFile( NextImage );
ImageEnView1.RunTransition( iettExpandingStar6 , 3000 );
// Display snowflakes in random positions
ImageEnView1.TransitionParams.WordTransWord := 'T'; // Snowflake in the Wingdings font
ImageEnView1.TransitionParams.WordTransFontName := 'Wingdings';
ImageEnView1.TransitionParams.WordTransFontStyle := [fsBold];
ImageEnView1.PrepareTransition();
ImageEnView1.IO.LoadFromFile( GetNextImage() );
ImageEnView1.RunTransition( iettRandomWord, 2000 );
// Transition, showing each letter of the word "ImageEn" in turn
ImageEnView1.TransitionParams.WordTransWord := 'ImageEn';
ImageEnView1.PrepareTransition();
ImageEnView1.IO.LoadFromFile( GetNextImage() );
ImageEnView1.RunTransition( iettWordWipeInAndOut, 5000 );
// Transition wiping the screen with the word "GO!"
ImageEnView1.TransitionParams.WordTransWord := '"GO!"'; // Enclose in quotes to avoid cyling. Small words are best
ImageEnView1.PrepareTransition();
ImageEnView1.IO.LoadFromFile( GetNextImage() );
ImageEnView1.RunTransition( iettWordWipeInAndOut, 5000 );
Compatibility Information
From v12.0.0, all extra transition properties were centralized in the
TIETransitionParams class.
Code changes are as follows:
Old Property | New Property |
IEGlobalSettings().TransitionsDrawAlternative | ImageEnView1.TransitionParams.AlternativeStyle |
IEGlobalSettings().TransitionsDrawShape | ImageEnView1.TransitionParams.TransitionShape |
IEGlobalSettings().PanZoomQualityFilter | ImageEnView1.TransitionParams.PanZoomFilter |
ImageEnView1.TransitionTiming | ImageEnView1.TransitionParams.Timing |
IEGlobalSettings().WordTransitionParams.Word | ImageEnView1.TransitionParams.WordTransWord |
IEGlobalSettings().WordTransitionParams.FontName | ImageEnView1.TransitionParams.WordTransFontName |
IEGlobalSettings().WordTransitionParams.Style | ImageEnView1.TransitionParams.WordTransFontStyle |
IEGlobalSettings().WordTransitionParams.Quality | ImageEnView1.TransitionParams.WordTransQuality |
