Topic: Quality loss with portrait images

Hi all,
I'm testing the free version of Simpleviewer before I purchase the full version.
I'm using svBuilder to create my galleries (images are resized/rotated beforehand, not in svBuilder) . When done, I review the gallery (offline or online) and notice strange quality loss with all portrait images, while landscape pics are ok. When I look into /images folder created by svBuilder, they are fine. They only look corrupted when viewed in browser. (The issue is most apparent when looking at the watermark.)
Any suggestions?

Gallery URL: http://svadobnyfotograf.peterazor.com/g … 1_galeria/

Changing the SimpleViewer-Pro option imageSmoothing from its default value of TRUE to FALSE may help: http://simpleviewer.net/simpleviewer/pr … #mainimage
However, with SimpleViewer-Standard (with the imageSmoothing option not available), you may need to try different size and quality settings when resizing your images before feeding them to svBuilder.
Also, make sure that the maxImageWidth and maxImageHeight settings have been set to the width of the widest image in your gallery and the height of the tallest image in your gallery respectively: http://simpleviewer.net/simpleviewer/pr … l#standard

Portrait Image quality looks fine here at this URL: http://svadobnyfotograf.peterazor.com/g … 1_galeria/ when compared to the original JPGs.

Can you post a screen grab of the issue?

Felix, here: http://peterazor.com/na-stiahnutie/simp … -issue.zip (watch the belt around the dress - it loses some detail in screengrab)
As I was preparing the files you requested, I noticed something. When I open the image in new tab, it's identical with the original. It only loses tiny bit of detail/sharpness when displayed within gallery. So it seems there's no problem with svBuilder as such because it there was, the file svBuilder exports after creating a gallery would be corrupted too. Am I right? If so, then it only seems to be an issue with actual display of the images.

Thank you for providing the screenshots.

Yes. I believe the problem you experience is caused by SimpleViewer resizing the portrait images on-the-fly to fit the image area in conjunction with the default setting of imageSmoothing="TRUE" (which can be changed only with SimpleViewer-Pro).
Also, with SimpleViewer-Pro, you would be able to change the imageScaleMode in order for images to not be scaled at all: http://simpleviewer.net/simpleviewer/pr … #mainimage

A suitable workaround for SimpleViewer-Standard might be for you to reduce the dimensions of your portrait images so that SimpleViewer does not need to resize the images to fit into the image area.

Re: Quality loss with portrait images

Thanks for your reply Steven,
now that I know this can be solved in Pro version, I'm going ahead with purchase.
P.S.: Just out of interest (off-topic), is there any chance it will be possible to password-protect galleries? That's the only feature I'm missing, everything else works great.

This is not possible with SimpleViewer itself but can be achieved at your web server level through htaccess.
Try a web search with terms such as 'htaccess password protection' for more information.
