hello manuschwenderer.ch, click on the brush button and then click the apply button to get the final render of the panorama. the inpainting algorithm will fill any empty area around the image. the process takes lots of time, cpu and memory. the result is reasonably good, mainly for areas that do not show complex details (i.e: sky, or meadows in the background). hth stefano

hello william, thank you for clarifying things. i am an affinity photo user indeed. maybe it is just a misunderstanding, in that i presumed (my fault) lklf's post was about photo. maybe having separate forums for photo end designer would help in avoiding such kind of misunderstandings... and yes, a "text along path" feature would be useful in photo too.

meb, something escapes me. i start with a new, empty document. i select the pen tool and draw a line, then i drag its nodes to make it a simple curve. i then select the artistic text tool. at this point: - a box appears around the curve, as if it had been selected with the move tool - if i hover the cursor over the curve, i see no wave under the A (the artistic text tool shows an A; while a T is shown for the frame text tool) - red horizontal lines and vertical green lines appear when the cursor position corresponds to the image center or to the side of other objects in it, but no wave under the cursor - if i click any point of the curve, the box around it disappears and the text blinking cursor appears where i clicked - at this point, if i type any text, it does not follow the curve. where am i doing wrong? thank you stefano

hello jim, thank you for your reply. you are right, and my scanner does have a descreening feature. however, you may happen to work with images that were scanned by others, who didn't know about that feature, or didn't care to activate it, or whatever. i experimented a bit with the tools that AP already offers, and achieved quite satisfactory results applying the following filters: 1) fft filter to the original image 2) frequency separation filter to the fft-filtered image 3) gaussian blur to the high frequency resulting layer 4) unsharp mask to the low frequency resulting layer i'm no expert in this field, so there may probably be a better approach, and maybe more than one. in addition, all of the above steps require some experimenting to find the parameters that best configure the filters. for example, i found that the optimal configuration of the separation filter causes all (or at least most) of the noise that the fft filter could not remove to go to the high frequency layer. this is also the maximum detail desired on it, so you can start with a 0 radius and look at the preview to find the value where the noise stops to become more and more visible and stays constant. usually the optimal radius value appears to be between 0.8 and 1.5. i guess that a new descreening filter could be implemented as a sequence of filters, with 4 controls: - precision of the fft filter - radius of the frequency separation - radius of the gaussian blur - radius of the unsharp mask i feel (but i could be wrong) that there may be some correlation among the parameter values, especially among the three radius values: this could simplify the user interface of the filter, or at least allow to set some meaningful default values. optionally, the filter could offer to display the fft window and manually paint over the frequency nodes. i know that this is far more simple to put in words than into lines of code... but i'd really be happy to see something like this in one of the next releases.

hello all, i wonder if affinity photo implements a descreening filter (useful to eliminate the moiré effect found in images that were scanned, i.e. from magazines): maybe i missed it, but i could not find anything similar in the filters menu and live filter layer menus i think such a task can be done through a sequence of operations (like scanning at a resolution highr than needed, then sampling down to the desired size, then applying a gaussian blur, and finally sharpening back). any suggestion will be welcomed. thank you stefano
