  1. I think that it behooves you to try out your batch process with a single file first, and to ensure that your output destination (or filetype) is different from the source. John
  2. I have not had this problem on any of my external plugins (Nik, Topaz, et al). They either work, and return immediately or within a few seconds, or they don't work at all (Filter Forge 8). John
  3. Many perfectly workable plugins have this "unknown" status. I would guess that the plugin does not provide Photo with some crucial bit of information that Photo is looking for. Hence the option to allow unknown plugins to work. John
  4. Look at the Affinity Help page for Setting White Balance: https://affinity.help/designer/en-US.lproj/index.html?page=pages/Adjustments/adjustment_whiteBalance.html?title=White Balance adjustment John
  5. If @SurJones is unwilling to use a beta for production, then would it be possible to use the beta to create the numbered list, then copy it and paste into the Designer 1.6?. John

    Arcs or Arches: a macro to bend images

    This is an updated version of the Polar Quadrant macro I have posted earlier. Consider a rectangular image that you would like to bend into an arc: The macro has two parameters. The first (a or Sector Width) controls the fraction of a circle that the altered image will occupy. The default value of 1 produces an arc of one eighth of a circle. Reducing this to 0.5 gives one quarter of a circle. This image this parameter set to 0.5: The second parameter (b or Height below Top) controls the position of the centre of the circle. Setting this to 1 places the centre at the bottom edge of the image. Reducing the value places the centre above the bottom, thereby reducing the radius. The following image has this parameter set to 0.75 (and the first to 0.5): A few notes: The parts of the final image outside the sector are transparent. The parts within the sector retain the original background colour. The macro works with the latest 1.7 Beta (333). I have tried to set both the default parameters to 1. However, in the 1.6 version, it insists on setting the default of the second parameter to zero which gives you a blank output! You will need to increase this second parameter. It seems to perform properly in the 1.7 beta. The image layer is rasterized at the start of the macro. If you apply a small value of the Height below Top parameter (below 0.5), You will get a partial (or even full) mirror image in the bottom part of the screen. I have left this, since some users might want to utilise it. Otherwise you can crop the image. The macro comprises a rasterization followed by Filter > Distort > Equations with the following lines for x and y: x=w*atan((x-w/2)/(h*b-y))/(180/pi/a)+w/2 y=h*b-sqrt((x-w/2)^2+(h*b-y)^2) Here are the macro and macro library (containing the one macro).

  7. The control point tools in the Nik plugins are unique and cannot always be emulated in Affinity's tools. One plugin I would like to see working in Affinity is 4N6's Color Deconvolution plugin. It looks to be able to do wondrous things that I cannot see Affinity doing by itself. I also find Topaz's AI Clean works wonders with scanned slides. John

    Color problem with Nik Collection plugins

    I tried DxO Viveza in the new beta 333 on a histological image and it looked fine. John
  9. As a matter of getting your point across, I would suggest that you would have been better to put it like this: On their web page [link] Serif has claimed that John
  10. This quote is rather unhelpful without any indication of the source or the date. John
  11. That is what I had assumed. Thanks for the pointer to the help documentation. John
  12. You can. If you edit a jpeg or tiff and do not add layers or effects then Save will save in the same place and as the same filetype. With more complex editing, you need to export. Where you draw the line is unclear however. I only discovered this by accident. It does not seem to be well-documented. John
  13. I scan a black-and-white image using VueScan using the B/W Text mode and save as a Tiff. If I open this in Corel Paint X7, it identifies the image as being 1-bit. If I open the same image in AP 1.6, it automatically converts it to 8-bit sRGB. I have to convert it to an 8-bit greyscale to do anything useful before export. Even if AP will not deal with 1-bit images, I think the least it could do is to treat it as an 8-bit greyscale rather than RGB! It does the same in 1.7 beta. John

    Sorry about that. The 'this' should have had a link attached. I was just trying to encourage @Bruce E. Gallie to follow the link to the PagePlus site. John
