I have an imageenmview component in a panel. when i re size the panel, imageenmview re sizes too but the thumbnail does not stay center as it was originally setup. Anyway, the thumbnail could stay center?
If i can ask more, could the thumbnail be also re sized too as the imageenmview get re sized? like that, if i get a bigger imageebnmview, i would also get bigger centered thumbnail.
Thanks.

Hi
Do you mean that you are displaying a single thumbnail/image and always want it to remain in the center despite resizing the control?

Not a single one. Every thumbnail represent a layer. Right now if i stretch my imgeenmview to the right, the gray (Photolike) background stretches but all the thumbnails do not move. They are still at the same location (That was the center of the imageenmview originally).
I have attached a screenshot.
Thanks.

In the developing version you can set ThumbnailsCentered to true.
Email me if you want a pre-release.

That is fine Nigel, I can just wait for the full release. I do not like to play with betas :)
Thanks for the update.. |

Bill, I found a way to handle that by using the imageenmview.width and the thumbnail width. It works fine but when the thumbnail becomes too big, the image is pixelated. I guess that makes sense.

Can you post your code?

This is assuming that my imageenmview original sise is 269 and the original thumb size is 100.
LayerView.ThumbWidth := RoundEx((LayerView.Width * 100) / 269);
LayerView.ThumbHeight := LayerView.ThumbWidth;
LayerView.HorizBorder :=
RoundEx((LayerView.Width - LayerView.ThumbWidth) / 2);
That centers and fits...

How do you eliminate the huge borders on the left and right sides of the thumbnail? SideGap is set to 0.

I really do not. I kind of like the photolike borders. If I had to, I would set my thumbnail width the same or close to the imageenmview width.
For example, you could set your imageenmview width at 120 ad your thumbnail width at 100. That would leave you 10 pixels on each side.
If you always want 10 pixels on each side when you resize, you would just have to modify the code to reflect that.
thumbnail width + 20 = imageenmview width.
Do you see what I mean?

Hi
No, the new version won't automatically resize the thumbnails to the window.
That could potentially be quite slow while drag resizing the window, so you should delay the resize using either a TTimer or by posting to the window.
Also it will be slightly faster if you put LockUpdate/UnlockUpdate around your code.
There is no reason the view should become pixelated with quality images, so ensure you are not using EnableLoadEXIFThumbnails.

This proportionally resizes the thumbnail reasonably well, without large side margins. Set StoreType to ietNormal, GridWidth to 1, SideGap to 8, HorzBorder to 0, UpperGap to 0, VerBorder to 4, Width to 169 in Object Inspector. It is assumed it could be improved; however. It is quite fast with a I7 processor and mid-range graphics card on Windows7- speed does not seem to be a problem and with photographic images it is not pixelated.
procedure TForm1.ImageEnMView1Resize(Sender: TObject);
{ Proportionally resize the thumbnail }
var
iAspectRatio: Extended;
begin
ImageEnMView1.LockUpdate;
try
ImageEnMView1.ThumbWidth := ImageEnMView1.Width - 28;
iAspectRatio := 0.77;
ImageEnMView1.ThumbHeight := Round(iAspectRatio * ImageEnMView1.ThumbWidth);
finally
ImageEnMView1.UnLockUpdate;
end;
end;

I like your pictures..Very soothing...I added the lockupdate to my code. I really does not know what it does. Maybe I should check the help file :)
Thanks. |

@Bill
Yes, you're right. If you are using the store type of ietThumb then the images will be lower quality if resized.
In the new beta though, you can use ietFastThumb, which automatically reloads the image from file when needed (without the memory overhead of using ietNormal).
