  1. I noticed this in the recent update notes: Is that relevant to this discussion?
  2. Looks like Xara is an subscription-based online graphics app. Are you suggesting using Xara as a go between? That is, subscribing to another app to translate Affinity Photo files? A $12.95 per month subscription doesn't seem like a great solution. Or are you suggesting using Xara instead of AP? That's not an option for me, as I don't use subscription-based apps. As far as I'm concerned, formatting is not as important as edibility. Even if all formatting is lost, it would at least save the time of re-entering all the text, which is time consuming and error prone.
  3. Are you saying I can export in one of those formats, then open in Photoshop and be able to edit the text?
  4. That makes it a bit challenging to exchange files with PS users. Seems like if editable text can be imported, there'd be no reason it could not be exported. Maybe it's a copyright issue, PS's file format is proprietary?
  5. When I export a document in Affinity Photo in PSD format, text layers are no longer editable.Text layers are not exported as text at all, they get converted to pixel layers. It makes no difference if I select "preserve accuracy" or "preserve edibility." Is there any way to export to PSD while maintaining editable text layers?
  6. This discussion has taken a pointless turn. What difference does it make how AP represents and arranges image data? I create and edit files in AP format, but save them out in TIFF, PNG, or JPG formats. It doesn't matter to me HOW AP saves the data internally, it's the data that AP saves that's important. Even more important for this discussion, a portion of those data have been made non-editable for some unknown and apparently arbitrary reason.
  7. Affinity Photo HAS all the necessary functionality already, they just disable it for the alpha channel. You can currently select and edit (using all the existing editing tools) any channel EXCEPT the alpha channel. So it's not a matter of adding new functionality, which I could understand not being a high priority. Unless it really is some intellectual property issue, it would appear they are intentionally crippling their software. I'd like to hear an official response as to why they don't do something that's about as simple as changing the value of a Boolean variable.
  8. I guess I touched a nerve with this post. I recently discovered another problem associated with the way alpha channels are handled. If you let AF create the alpha (e.g., drawing a circle on an otherwise empty canvas with a transparent background), the empty space remains empty in AF, but not necessarily when you save as TIFF and open in another app. I noticed this when I was making light-colored buttons with rounded edges. When I placed the light-colored buttons on a light-colored background the buttons had a black border. They were not antialiasing correctly with their background, and I've not been able to eliminate that dark edge completely. In Photoshop this was never an issue because I always made the edges of the button graphic match the background the buttons would be on, so they always had nice-looking edges and blended seamlessly.
  9. It's not just textures. Transparent textures are expensive in 3D games, and I use them very sparingly. For me, it's creating the 2D interface where control of the alpha channel is most important, something I do all the time, where it's not just making cutouts. For example, a button with an alpha drop shadow can be created in AP, as I eventually learned, it's just a different workflow. The same is true for other alpha effects I used to do in PS. I've been able to get AP to do what I've needed to do with the alpha channel, it's just not always as direct or obvious as doing it in PS. However, regardless of AP's target audience, there doesn't appear to be any reason NOT to make the alpha channel accessible. All they have to do is make the little icon that indicates that a layer is editable work for the alpha channel (currently it's a button that does nothing). The editing tools are already there, they're just blocked from working in the alpha channel. It seems like they're going out of their way to treat the alpha channel as a special, non-editable layer.
  10. If I try to close a document that has not been saved, I get the prompt to save the file. If I do a save, the document doesn't close. I have to close it again. This is not normal behavior for a Mac application. The file should close after saving without me having to close it again.
  11. By arbitrary position, I mean any location within the document, NOT any rotation. I'm talking about horizontal and vertical lines. By selection, I mean a selection made with a marquee tool in a pixel layer. (There is more than one way to draw a line.) In the attached image, I made a selection with the Column Marquee Tool, and filled it with white on a black background (left line). Then I made another column selection, filled it, then dragged it a few pixels to the right (other line). You can see in the screen capture that the second line is still selected, but it's gotten wider and darker, the filled area now extends past the "selected" pixels. So it looks like it's not possible to be precise with either vector or pixel objects. I understand why this is the case with vector objects, but a pixel is a pixel. A selected area of pixels should NOT change its appearance or size as it's dragged around the document.
  12. So it's not possible to draw a precise, single-pixel line in an arbitrary position? What about filling a one-pixel wide selection? Why does that also depend on position? Shouldn't a filled selection include all the pixels within the selection, and none outside, with the same color/transparency? It looks like it's doing antialiasing whether I want it to or not. Is it not possible to do precision, pixel-perfect drawing?
  13. Thanks, that'll be good to know if I ever get Affinity Designer. What about the Rectangular to Polar filter, seems like that should do the trick, but it just turns the text upside down and tilts it.
  14. How do you make text follow a curve, for example wrapping text around a circle? I've found a video that shows creating an ellipse shape, then clicking on it with the Artistic Test tool, but that doesn't seem to work in the desktop version of Affinity Photo.
  15. I'm having trouble drawing single-pixel, opaque, non-antialiased lines. I can't find a way to turn anti-aliasing off, and the lines are either more than one pixel wide or partially transparent. I'm only talking about horizontal and vertical lines. In the attached screen capture, the line on the far right is a curve with a 1-pixel white stroke on a dark gray background. The line is vertical, but you can see it is more than one pixel wide, and it's not white. The line on the far left is a filled pixel selection. It looks correct, a single pixel wide and opaque white, but if I move it (the line second from the left), its width and color changes. I need to create a single-pixel line that's not transparent and a known color, like the line second from the right imported as part of a Photoshop document.
  16. Thanks. It wasn't obvious how to get the Stroke panel to show up with the text selected, but I got it working. The results are pretty similar to the bold text I'm trying to match.
  17. How do I set text to bold (or italic) if the font doesn't have those styles? I'm trying to match some text created in Photoshop, but in AF the bold and italics options are not available unless the font supports them. Can I only apply styles are that available for a particular font?
  18. I finally got it working. Thanks again. I discovered I'd missed this one critical step. If you don't opt-click the thumbnail (obviously), the mask is invisible, and it looks like nothing is happening. One more thing I still can't seem to do is paste into the mask. For example, if I want to copy an alpha channel from one image to another.
  19. That works (cmd-click on Mac), but it selects all the pixels in the layer. I'd like to just select the pixels within the original selection, but this is a limitation I can adjust to. Thanks.
  20. That just changes the size of the selection area. A rectangular marquee just gets bigger or smaller.
  21. How can I shrink a rectangular (or other) selection to an irregularly-shaped object? In Photoshop I can draw a rectangular marquee around some shape, then nudge the selection (cmd-arrow), and the selection shrinks to only include the filled pixels in that layer, edges and holes are excluded from the selection. Is there a way to select just the filled pixels, maybe a different selection tool or selection options, within a given area without selecting the empty space?
  22. How about "Creating/Editing the Alpha Channel" for Photoshop users. This is something I still have not figured out, and still rely on Photoshop for. There is nothing in the manual or any of the tutorials about the topic. Alpha channels are the only thing I've found that are treated completely differently in AF than in Photoshop, and the only (big, glaring) gap for me in the tutorials and documentation.
  23. I do a lot of UI graphics and textures for 3D models that have transparency, so having access to the alpha channel, beyond just creating masks from selections, is very important to me. I've tried with the patient help of people on this forum to edit the alpha channel of a TIFF, and have not succeeded. I've also tried to create a new TIFF with an alpha channel without success. Creating and editing TIFFs with an alpha channel is the one thing I still need to use Photoshop for. Which is inconvenient as I have to use someone else's computer. I understand it is possible to edit the alpha channel (in theory), but it's not like editing other channels or layers. The pencil icon that indicates when a channel is editable, does not work for the alpha channel (Composite Alpha), it has no effect. You can't paint in the alpha channel, sample color, do fills or effects, or do much of anything. The alpha channel seems to be separate and treated differently from other channels and layers. I'd like to see the alpha channel treated like just another grayscale layer, so that ALL tools work with the alpha channel just as they do with other layers, without the additional steps of creating/merging new masks and layers. Just click the Pencil tool, make the alpha channel editable, and then edit it. Another, related change I'd like to see is being able to see the entire image even where the alpha channel is black. As it is, you can't see parts of the image where the alpha channel is black. I believe this is possible too, but is not obvious how to do it. Ideally, it would be a toggle to see the entire image or the alpha-masked image.
  24. Thanks for all your help, but I'm just not getting this at all. I've tried MANY times, and just cannot seem to get it to work. Every time, I end up spending way too much time, getting frustrated, then giving up and using someone's else's computer with Photoshop, and getting it finished in a few minutes. Most recently, I tried to create a new TIFF with an alpha channel (a black rectangle with a gray alpha), and failed at that. I don't understand why doing anything with an alpha channel, which is treated just like any other layer in Photoshop, is so difficult in AF. The functionality to edit a grayscale channel already exists in the program. There's even a Pencil icon for the alpha channel which the hint says makes it editable, but doesn't. Access to the alpha channel seems like basic functionality for a program such as this.
