The main purpose of seam carving is to reduce the width (or height) of an image without scaling (squishing) the image. This effect calculates the line through your photograph with the least amount of changes and deletes that line shifting all pixels over to fill the gap. This is often called "content aware resizing". Use This effect is designed to be used with natural photographs. It is not designed to be used with an active selection. So, before running the effect, press Ctrl-D to remove any active selection. Run the effect and click the OK button. One line of your image will be removed. Note: Version 1.5 allows more than one line to be cut at a time. However, there is a limitation on how many lines can be safely cut at one time. You may find that only a few lines may be cut before you need to run the effect again so that more lines can be safely cut. Version 2.0 removes this limitation. Please be patient when carving more than a few lines at a time. Due to the nature of the algorithm, the entire effect is run in a single thread. So, it may take a few seconds for the effect to show up after you move the slider. If you wish to shrink your photograph even further, press Ctrl-F to redo the effect. Continue pressing Ctrl-F until your photograph is the desired size. Protecting Elements This effect will only carve out areas with full alpha. That is, it will ignore areas of your image where the alpha is set below 255. You can use this to your advantage by selecting any area you wish to protect then use the Adjustments > Transparency plugin to lower the transparency slightly. Once you've finished with all of your carving, use the Adjustments > Transparency plugin to restore your image to full opacity. Download (For paint.net 4.0.6+): http://forums.getpaint.net/index.php?/topic/32048-v You'll find it in your Effects > Photo > Seam Carving menu. NOTE: This is slow on camera sized images. Sliding the slider up to 200 could take a couple of minutes to see anything. This is all due to the fact that it is running the algorithm in a single thread. Updates v2.2 - Improved messaging.
