Batch is very clunky, and also it can’t seem to work dynamically with auto perspective correction (e.g. Still, it’s a keeper for the time when a really complex auto-rectification is required. It’s not a quick go-to three-second solution, even though the automatic rectification is impressive and better than ShiftN. Unfortunately, Darktable as a standalone takes way too long to start up, and the interface is non-standard. … but when called from PhotoLine it crashed repeatedly. However, ShiftN led me to DarkTable, which has an auto-correct which knows about corners and which works wonderfully as a standalone… Adjust of its line-length options improves matters greatly, but the results still have skew.

But it it clearly meant for buildings, and there’s no way to drop on a couple of manual control points.
ShiftN is nice, especially the automatic bit and it works fine.

It’s available in a more advanced form in the free Darktable, the open source equivalent of LightRoom. The ShiftN freeware has an interesting automatic correction.

Likewise the Windows freeware Perspective Image Correction could not place reference points outside the frame. Otherwise it could have been called as an External by PhotoLine. But a bit too simply, as it too can’t place guide-points outside the frame. Nor can the Perspective Pilot plugin work, refusing even to launch in PhotoLine.Ī Paint.NET plugin was a possibility, Quadrilateral Correction, and it works very nicely and simply. Possibly Krita or GIMP could be called, but they take ages to load. Which, I find, is the one Nik module that doesn’t work as a plugin with PhotoLine. Or DxO’s £125 Nik Collection 3 which now includes a Perspective tool, Perspective Efex. One overkill solution seemed be the DxO ViewPoint plugin, a slick £43 utility meant for architectural photographers. It uses an imprecise manual ’tilt’, which is very far from ideal. One needs to manually add a ‘stop’ to do this.Īre there alternative plugins? The $25 PTlens initially looks like DCE Tools on steroids, but on trying it I see that its curious Perspective correction works on neither the ‘place dots’ nor ‘auto-mask detected square shape’ principle.
Also, while making such an action, I notice that PhotoLine doesn’t automatically record tool selection (e.g ‘select Crop tool, open Crop, wait for user input’). This is far from ideal for several reasons. The very clunky free solution for PhotoLine is then to have an Action enlarge the canvas to 3000px and hope this is larger than the picture being rectified. So the process cannot be made into a simple Action that says – “Take Canvas up to 115%, open Rectify Tool”. But PhotoLine cannot enlarge the Canvas by a %. That would give the space for placing of points. The simple solution in PhotoLine should be to enlarge the Canvas first in PhotoLine, before Rectify. It anyway fails to return results for some reason, when IrfanView is used as an external programme from PhotoLine. One of these can work in IrfanView, but it is painfully clunky and fiddly compared to the old DCE Tools.
Other potential free plugins are also old and fail to work. The Rectify tool is not sufficiently powerful, being unable to place points beyond the bounds of the picture, as the old DCE Tools could.īut the old 32-bit DCE Tools is defunct in PhotoLine as it cannot be successfully run to completion in either PhotoLine or via the AlphaPlugins Launchbox.
