  1. PDF does not have a DPI setting, so we deduce one from any embedded bitmaps we find. Obviously it doesn't make much difference to the vector content, but doing this does mean that any areas rasterised on export will get similar quality to the images already there.

     

    I tried exporting at 72dpi and 192dpi and then imported into PhotoShop. It used 300dpi for both, so I think it is just lucky its default happened to match what your document originally was. I'm not sure where you are seeing DPI in Illustrator, but when I exported to PNG it wanted to use 72dpi for both, so again I don't think it is doing anything clever.

  2. This is by design, I'm afraid. EPS specifies the document size as an integral number of points. The document size is 102.75pt x 137.25pt. You can see this by changing the document units to points, selecting the white background rectangle, and looking at its size in the Transform tab. The height gets rounded up to 138, which is why the top rectangle is offset by 0.75pt. (The offset is at the top rather than the bottom because EPS puts its origin at the bottom left instead of top left). If you import the EPS again, you'll see that the white background rectangle has the same size, and the page is 0.75pt taller. 

     

    We do write a hi-res size as well, but since it's optional and many other apps (eg, Preview) ignore it, we ignore it too.

     

    When you change your document 72dpi, because the document units are pixels, you are actually making it smaller. You are also giving it an integral size in points, because there are 72 points per inch so 183px at 72dpi = 183pt exactly. That's why the problem goes away.

     

    EPS is not a great format, especially for web-related work. If you must use it, I recommend you set your document size to be an exact number of points.

  3. I haven't decided what to do about them. At the moment we output simple gradient fills as vector. To stop Illustrator warning about them we'd have to rasterise instead. That will make the PDFs larger and lower quality. That would be a shame, especially as Illustrator does seem to import them OK (it rasterises them itself). I could make it an option, but I doubt many people would find and use it, so that would be a cop-out.

  4. It seems to be to do with the way the clip is made. If you first create the text, then Copy the pattern, select the text and use Edit > Paste Inside, the result is the same visually but exports as vector. You can get the same result by dragging in the Layers tab, but you have to put the pattern below the text rather than vice versa.

     

    Creating the clip by dragging the text alongside the layer you want to apply it to, seems to confuse Affinity because the text can have multiple strokes and fills. It's only safe to export as vector if none of the strokes or fills would be visible, and currently it doesn't bother to check.

  5. I'm not familiar with the term, "postscript hash text" - do you mean text that has been converted to curves?

     

    We don't force text to curves for PDF or SVG; currently we do for EPS, and for PSD it gets rasterised. There is an option to convert to curves, in File > Export > More, so the first thing may be to check that didn't somehow get switched on. Is it just simple text, or does it have a complex fill, stroke, transparency or effects, or is it used for vector clipping?

  6. The attached file exports to PDF fine with 1.3.5 but is completely black in the beta. The offending layer is named. It exports fine when that layer is deleted.

    This will be fixed in the next beta.

     

    I think the jagged edges might have to do with not setting the fill colour to empty/transparent when a layer/shape/node has child objects.

    That's right. For vector clipping the curve has to be a pure vector, without any colour of its own.

  7. Dave, use the img1.jpg in the first post!  Export to pdf as any of the pdf-x options and then try to load into Illustrator.

     

    Ah, I was expecting an Affinity Designer file and that looked like a screenshot of one.  I couldn't reproduce the issues in the first post with that (and it's hard to see where the rectangle on the nose would come from in a plain JPEG).

     

    It does look like Illustrator is having a problem with our CMYK JPEGs. That would be an Illustrator limitation, as Acrobat Pro not only loads them correctly but the pre-flight check confirms they are PDF/X-1a. I'll see if we can work around it. PDF/X-3 and above will be OK because that supports RGB.

     

     

    Not sure I fully appreciate the 'it should be easy for you' comment. We're only trying to help!

    I do appreciate it. I was getting lots of reports of issues, but no sample files I could reproduce them with.

     

     

    I have attached a file that doesn't work at all.  x1 and x3 won't save because the 'Estimate File Size:' doesn't ever get past 'Calculating...', and x1 shows the same issues in AI as the img1.jpg example above.

    Thanks. I've found and fixed a problem we were having with alpha with that. It now exports, but Illustrator is very unhappy with it. It says, "An unknown imaging construct was encountered". Again, Acrobat Pro pre-flight checks say it is fine. I'll continue to look into it.

     

     

    I send you the original watermelon moon file to your support address.

    Thanks. I can reproduce the nose problem with that.

  8. PDF export has issues. Below is a comparison of the same SVG exported from iDraw and the new beta.

    The app store version also suffers from jagged/stroked edges but it maintains transparency instead of the solid black background. I tried all formats of PDF and they were all the same. The black background is part of the image when opened with other apps.

    AD also rasterises where iDraw exports vector. The beta doesnt give the option but the app store version exports nothing if rasterise is disabled.

     

    Can you attach the original file so we can take a look? And which app are you using to look at the PDF?

     

    You can control whether unsupported features get rasterised or ignored with File > Export > More > Rasterise > Nothing.
