Mauro Messerotti Posted August 13, 2017 Share Posted August 13, 2017 I am used to take daily pictures of the Sun, which appear as a filled circle on a black background. Such pictures have to be derotated by a certain angle to get the solar North exactly upwards and the South downwards in the x and y reference system of the image. Anyway, being an AP-iPad newbie, I have been not very successful with the relevant workflows I have tried. In fact, I have used the canvas rotation feature, which worked fine, but this resulted in an image which was obviously not squared in x and y. Hence, I have been unable to fill the missing parts to get a squared image that can be saved. Then, I have tried to work with a selection containing only the solar disk, but I got lost when trying to save a final image. Therefore, I would be grateful to get some hints about the most effective way to apply the rotation and to save the result. Thank you in advance!

Staff MEB Posted August 14, 2017 Staff Share Posted August 14, 2017 Hi Mauro Messerotti, Welcome to Affinity Forums Not sure i understood what you are trying to accomplish but have you tried to select the layer and use the rotation field in the Transform Studio to rotate it?

Mauro Messerotti Posted August 14, 2017 Author Share Posted August 14, 2017 Hi MEB, Thank you for the prompt feedback. I have just taken a picture of the Sun, which I have cropped to get a square canvas with the Sun at its centre. If I activate the layer menu, I see I have only a puxel background layer (see attached). If I activate the Transform Studio, I cannot operate any rotation, as all the options are greyed. What did I miss? Cheers, Mauro Quote Link to comment Share on other sites More sharing options...
Staff MEB Posted August 14, 2017 Staff Share Posted August 14, 2017 Thanks for the images. You need to have the Move Tool (the arrow icon) selected. You will see the white background of the canvas (or transparency checkerboard if you have set the document to use a transparent background) on the corners, but you can add a Fill Layer filled with black and moved it to the bottom of the layers stack to "fix" that (assuming the black around the sun is pure black).
