I have used equations to resize my images as described in this thread. I use the Parameter a to adjust the final image size to the desired maximum. However the parameters are constrained to lie between zero and one (inclusive). In this macro, zero gives a size of zero and one gives a size of 4000px. The parameter a is a multiplier for 4000 so that 0.2 gives a target of 800px. I have found that it is much more convenient to enter a fraction in the parameter box so, instead of entering 0.2, I can enter 800/4000. All the user has to do is to remember the denominator should be 4000. The ability to enter fractions is documented for other parts of the user interface, but I thought it worth mentioning that it works here as well. John
Hi all, I am new here, but I have AP a long time. Since today it works perfectly. But today I had an issue. If I choose a filter, which normaly it opens a window with the settings (parameters), it shows me the attached icon / cursor. If I click and move the mouse, than I see, that the settings is changing. But I want to do that with the "normal" slider and numbers. I resettet all settings in AP, but it doesn't changes anything. It is maybe a windows 10 or affinity photo problem or can I change it in a setting? Windows 10 are with all updates. AP I tried also 1.6.93 and 1.6.103. I have a Surface Pro 4. Hope anyone can help me. Kay-Uwe
@atfitzy posted a thread about re-shaping a text block. I tried various Equations in Filter> Distort and the best I could come up with is: x=x y+(h-y)*(w-x)*x/w/w/a This produces the required arch in the upper margin of the block. The a parameter allows the user to increase the stretching effect. The default of one has no effect; reducing it will increase the effect. However, I find that reducing the parameter has no effect until the value goes below half, after which it has the desired effect. I can get the desired effect by putting a multiplier at the start of the equation: y+2*(h-y)*(w-x)*x/w/w/a Here are a couple of arched images using this formula: Otherwise the formula works as desired. Before I commit this to a macro can anyone explain this unexpected behaviour in the parameter value? John
I've had several goes at this, and it happens every time ... I have an image with two layers, and the top one is selected. I've recorded a macro to do the following: - increase the canvas size to 200% +10 pixels (two operations) - move the top layer over to the right-hand edge of the canvas - flatten the image It works OK until I close the Library panel and re-open it (without necessarily closing and restarting AP) -- the transform parameters have changed, and have to be changed back to make the macro work properly. I'm running Windows 7, btw. These are the parameters as recorded: ... and these are the parameters on re-opening: I use this process for creating stereo pairs from separate source images, and it's a very fiddly affair when there are several (or many!) pairs to process. I'd previously used a script in Paint Shop Pro without problems.
