An appropriate downsizing algorithm would probably sharpen an image. However, I would be reluctant to claim that it never created artefacts. If you are upsizing, then it is much more dependant on the kind of image - and on the algorithm. It would also be more likely to cause artefacts because it has to create pixels which were not there before. Having said that, modern specialized upsizing software can do amazing things. John

If you are using these images in a website, then the dpi is irrelevant. What counts is the xizein pixels. John

Yes, but it also allows all the angles in between. John

So what you actually need to do is to rotate the map rather than flip or mirror it. John

I have now re-installed Photo 1.6 and recorded my Change DPI macro for 120ppi. It works OK with Photo 2.4.1 I attach below the macro Change DPI to 1201.6.afmacro and the updated macro library to include this macro Change DPI 1.6.afmacros John Macros Change DPI 1.6.afmacros Change DPI to 120 1.6.afmacro

@CJP001 I have recorded my macro to change dpi to 120ppi. I was just about to upload these when the Affinity site crashed! I will try again when I have had my tea! John

Thanks @walt.farrell. I was sure that I had seen that page recently, but I could not find it. John

I have been recording macros to change the dpi of an image without changing the physical size. These macros will not work in the current versions of Photo, but did work in version 1.6. I originally had a copy of the installation file for v1.6, but this was one of the casualties of me transferring to a new computer. I still have a licence for version 1, but I am told that version 1.6 is no longer available. Would it be possible to obtain a copy of the v1.6 installation files. The macros I originally recorded in v1.6 still work, but some users would like versions that create a different dpi to those I already provide. John Rostron

If you first create your series of bars using Power Duplicate, you can then use equations on the entire image: Filter > Distort > Equations In the Equations box enter x=x y=y+150*sin(6*pi*x/w) Then click on Apply It should give something like this:

Yes, impressive. The depth of field is narrow, but most is in foocus, notably the brakes on the antennae. What is it? I could probably work out what it is from my key (written by my old boss), but I would guess something like a male common mosquito Culex pipiens. John

I recorded those dpi-changing macros in V1.6 (I recall), the version before this error crept in. I have recently installed a new computer, so I currently cannot use this old version. When I do, I will record a 120dpi version. John

When you download the installation files, the default is to use the MSIX version. You are given the option of an MSI version, but it offers it (unnhelpfully) as an EXE file - it does have an .exe suffix. Just read down few lines to find it. John

I am about to transfer everything to a new computer. I have the information supplied by Affinity: I just re-install on the new computer. However, I seem to have lost my passcode for the V2 apps. (I do have them for V1). How can I retrieve my passcode? John

You can specify the resampling algorithm using Document > Resize in a macro, but the saved macro always uses the original image propeties when running, not those of the image you apply it to. Using Equations avoids this problem, but you cannot specify the resampling algorthm. John

Would this do what you want. This is for pixel images in Photo. John
