Hello,
i am a new user of imageen, sorry for my questions.
I'm rotate some face images with imageEn (layers).
How can i make the quality of the rotation result better.
See attached file. On the left side is the imageEn Rotation (Layers Demo). The edge of face looks not good enough for me.
Is there any anti-aliasing setting like in Proc.Rotate ?
The right example is rotated wiht corel photopaint.
Kind Regards
Markus

Hi
Yes, all the demos are recompiled with each release. Please download the "Layers" demo.
At the bottom right you will see the "Rotation Preview," which illustrates the new property. It is recommended to use the "Delayed" option as otherwise rotation of large images can be slow

Hi,
Could you please let me know if someone of the compiles Demos were compiled and updated with the latest ImageEn? I would like to test the rotation without having to install a TRIAL version as I have an older version installed.
I tested Layers.exe and RotateLayers.exe but the result is not much different from before.
Thank you |

Is there a way to rotate the image and have the same quality as I would have after calling ImageEnView1.LayersFixRotations()?
Even using ImageEnView1.LayersRotationAntialias := true; and different LayersRotationFilter I don't get the same result. Not sure if this is a limitation of ImageEn.
For example I managed to rotate and resize layers and have excellent results using graphics32 (http://andrefm.com/graphics32/index.html ; if it appears not to be that good, it's because the video was resized), but the issue with graphics32 is that it requires lot of work and coding. I need implementing many other features that are available in ImageEn and would have to spend long time to do with graphics32.
I saw one suggestion (http://www.imageen.com/ieforum/topic.asp?TOPIC_ID=1096&SearchTerms=rotate) where I would call LayersFixRotation at ImageEnView1LayerNotify, but after rotating many times the image quality is bad. Another problem is the layer boundaries/dimension (not sure how to describe better) would change. |

Hi Markus
Also, call TImageEnView.LayersFixRotations when the rotations are completed.

Hello Bill,
thanks for your reply.
I'm trying your tip, but with no change of the result.
So i consult the helpfile again, an I'm playing around with
LayersRotationAntialias and LayersRotationFilter but i never saw any effect.
Many thanks for spending your time.
Markus

You could try
ImageEnView1.UseResampleFilter := True;
ImageEnView1.LayersRotationAntialias := True;
ImageEnView1.CurrentLayer.ResampleFilter := rfBicubic;
// or
ImageEnView1.CurrentLayer.ResampleFilter := TResampleFilter(ResampleFilter1.ItemIndex);
If you need the best quality try: rfHermite, rfBell, rfBSpline, rfLanczos3, rfMitchell, rfNearest, rfBilinear, rfBicubic
If you need speed try: rfTriangle, rfLinear, rfFastLinear... Add these items to a TComboBox named ResampleFilter1.
