  1. Im not a professional, but have spent several months on AP. What seens to work best for me is to find a way to break the project down into separate files, do a merge-visible and assemble the merged images into a final version.
  2. So, I've had similar issues with lag and occasional crash using some of the simplest tools. But I figured out that it seems to happen on layers that have been resized, and if I rasterize the layer it works better.
  3. I still would like to know what resources are taken up when keeping documents loaded in the main menu. Do they take up RAM? Are they stored as some kind of virtual memory?
  4. Thank you Callum. I will see if I can find something reproducible. I did realize finally that I wasn't clearing the history which makes a BIG difference in file size. It would be good to have a better understanding of how some of the actions, which may be simple to use, have an impact on computer resources. I guess a lot of them are standard algorithms which I can research somewhere. Not sure how much I care yet. I just see that the more sophisticated I get with CG, the more my file sizes balloon and computer bogs down. So, I would think some understanding of this would help me parse my workflow.
  5. So, I'm just wondering if its a more efficient use of computer resources to create separate smaller AP files and embed them into a into a master file. I was hoping to find some kind of option where files could be 'linked" and therefore reducing file sizes. But I'd like to know if embedding has advantages other than organizational. Thanks for any feedback.
  6. I'm not sure if this question is answerable, but I'm trying to get a sense of when I'm reaching the memory/complexity limits of editing an AP file on my ipad. I have a 2nd gen 12.9" model with 64gb drive(only 17gb available)/4gb ram. I'm working on a 422mb file that is 5000x5000 8 bit resolution and at least 100 layers. I just started having troubles with the program crashing and I'm not sure if it's a bug that I can address or I'm just reaching the limits of what I can do on this system. So my main question is: Is there an idea of how much ram or disk space I should have available to work on a file of a certain size? I have to do more troubleshooting, but wanted to see if anyone has any ideas around this. Associated with this question is how much overhead does it take to use certain features in AP? For instance: - Does grouping small layers of bitmaps add to the file size/computational complexity much? Or should I just rasterize/flatten into larger bitmaps more often? - Using certain adjustments versus rasterizing those into the pixel layers? I know that using live filters takes more overhead. - Does the number of files loaded onto the home menu influence the editing of a single open file? I noticed that they open pretty quickly from the home screen versus opening the file directly from another location. So, I'm assuming that anything on the home screen is also loaded into memory to some degree. I'm not going to be able to upgrade for a while, so need to make the best optimal use of what I have. Thanks
  7. Has hiding the selection line been asked about before? I used this a lot in PS and it was very helpful when tweaking/aligning the image portion to see behind the marching ants. Also, even though I'm impressed with the image adjustment tools, some buttons for moving a single pixel at a time would be useful as well. Thanks
  8. I'm thinking it would be nice if there were more instances of the message: "Do you want to commit these changes",before one can move on, as there is for transitioning from some of the other personas. I tend to make the same repetative mistake of not pushing the check.
  9. Thanks for getting back to me Dan, So I uploaded three images of an AP file with two bitmapped sample layers and also the curves adjustment control showing three states. For the top layer I just selected the area outside of an oval and made the alpha channel (and text) more transparent. The center of the top layer text is still opaque. The first image shows the default state. The second image shows it when the slope is lowered to almost zero. The third image shows what happens when you raise the bottom end of the slope up close to maximum. My point here is that image 1 and 3 show no difference. What I've seen in other software is is that by raising the lower end of the curves upwards, the text outside the oval should become more opaque. I should also note that editing the center of the curves control doesn't seem to affect the image in a way that I would expect. Since I started this topic, I discovered another way to influence the alpha channel. So my life doesn't hang on solving this issue. Thanks.
  10. So, It appeares that I should be able manipulate the alpha channel of a bitmap layer in curves, adjusting the opacity. And I was able to adjust an image with the alpha set to fully opaque 255 downwards to make it more transparent, however, I wasn't able to increase the opacity of an image with a translucent alpha channel. Is there a reason for this? or am I doing it wrong? Thanks
  11. So, I just learned about an option in AP that is basically the 'copy merge' function when reading about something else here. When 'merge visible' is used it does not destroy the layers that it merges. It just creates a new layer of all the merged ones. That's basically all I wanted.
  12. Thanks for the assistance, all of you.
