Filters

Attention After changing any of the these settings you need to rebuild the gallery with the "All" checked (JAlbum 7) or "Build all" button (Jalbum 6.x) for the changes to take effect!

Convert to grayscale

Makes thumbnails or closeup images Black and White.

Em-square

Makes thumbnails or closeup images square-shaped — as I though in the beginning. But recent scientific research has proved that this filter rather makes the result the same size as the dimensions given in the "thumbnails" or "images" box (Settings / Images / Image bounds) respectively. I.e. it makes square-shaped thumbnails really if you leave 120x120 in the thumbnails box, but makes all thumbnails 120x60 if you put this value in the box. Works the same way for slidepage images (closeup images).

Zoom

Enlarge thumbnails / closeup images by this percent before applying the filters. Combinig with Em-square filter makes an interesting close-up detail effect.

Color Map

Assigns new blackpoint, medium and whitepoint colors (left to right) to images — this way makes a colorization effect. Combined with Grayscale filter makes a color gradient between the three defined colors. If you set the blackpoint to white, and whitepoint to black, this filter makes a negative image. Solarization effect can be achieved by defining the black and white points as black, and the medium as white.

Watermark

Writes a watermarked text on each image. The strength is controlled by the opacity setting. The color setting is not working at the moment because of some JAlbum bug. You can put dynamic variables on the images, like $comment, $originalDate of $fileName. The "$" sign tells the program, that this is a variable. (Take care of the upper/lowercase letters!)

Logo

Adds a logo/image to slide page images at the specified position. The filter does not resize the logo, so you first have to make it in the final size, and save it e.g. into the JAlbum's res folder (C:\Program Files\JAlbum\res on PC) as JPG or GIF or PNG. Using PNG format you will also be able to control the logo's transparency. You can put the file in any other folder too, or just have a direct link from the web, but in this case you need to specify the full URL path, e.g. file:///C:/adir/anotherdir/animage.jpg or http://jalbum.net/images/cup.png
