    Struggling to get this images at a smaller file size

    in Pre-V2 Archive of Affinity on Desktop Questions (macOS and Windows)

    Posted

    Maybe it's just not possible, but I feel like I'm missing something.

    I have this image that's full color at 3000 px by 3000 px by 72 dpi. It's coming in at 9MB+ as a PNG.

    I can't upload it here, because it's too large. https://ibb.co/Xsy8q3B

    Another image that's 2000x2000 is much smaller at 80k. I don't anticipate I can get this one that small, but 512k?

    Maybe it's not possible, but I just wanted to check.

    I've attached the 2000x2000 logo.

    These two TIFFs are different somehow (also rotation question)

    Straighten tool in Crop tool is really useful. It does not though offer automatic crop to remove transparent corners, and there is no Trim command either like in PS. Manual cropping it is.

    I think you need to set Document > Transparent Background to off. You should be able to just save over the original document as long as you have not inserted any non-destructive elements/layers.

    Okay, I'll try that straighten.

    I am creating one with transparent background off. I'll see what that does. Uploading to IA now. Takes a little but to go through derive which creates the previews.

    [EDIT: Yes, that worked. That's the easiest option by far.]

    I have found that Affinity Photo will often convert my scanned images (tiffs) to RGB, even though I scan them as greyscale or even black and white. It is something to do with applying an automatic profile.

    I worked in commercial printing for about a decade. This is the kind of thing that could be a big problem, but for me I don't really care. 🙂

    However, I notice that when I open a file that was scanned grayscale, AP applies a grayscale profile. I may be scanning some later and I can check it out and report back.

    Have I missed anyone mentioning this? You can straighten a document by:

    1. Select the Crop tool.
    2. On the Context Toolbar, select Straighten.
    3. Click on the beginning of a line that should be horizontal.
    4. Click on the end of the horizontal line.
    5. Complete any  remaining crop actions.

    No, you didn't miss it; I didn't know it existed! I'll try it.

    I think the first thing I'm going to try is to just remove that sliver of transparency and see what IA does with that. [EDIT: It didn't work. 😞]

    It's strange that I've not had this issue before in that I have scanned many things grayscale. The difference here, though, is I've been rotating and cropping. So... maybe I need to export with white matte every time I do that? I don't care; I just want to do what's going to work! 🙂

    Is there some kind of fundamental difference between rotate and crop vs. transform and crop as it pertains to layers?

    Thanks, all! I see what you mean by the lower left. I assumed that would be no issue. 
     

    I do have more PS experience but it’s from years ago. I don’t know how much has changed in relation to layers. I do recall using Flatten Image a lot. I’m really curious about simply cropping 0002 to see what happens. That would be a very simple solution to all of this. 
     

    I haven’t been as precise on these images obviously. 
     

    One thing I am curious about is how I’ve not had any issues with other images I’ve _saved_ as opposed to exported. Having said that, I’ve done a lot more rotating and cropping and scanning items 2-up which necessitated more rotating and cropping and exporting. 
     

    I have wondered if saving or exporting do two different things with regard to transparency layers. 
     

    Thanks all!!!

    Hi @thecompu and welcome!

    Document menu - Rotate 90º in your chosen direction:

     

    Oh, I have to do much, much smaller rotations than that. (I should have said so. Sorry!) I'm talking .. 1 or 2 degrees in one direction or another.

    Samples per pixel in 0000 is 1, in 0002 it's 2

    Bits per sample in 0000 is 16, in 0002 it's 16 16

    There's also an Extra Samples tag in 0002 which reads "Associated Alpha" and isn't present in 0000

    There may be other differences, but I'm not clever enough to tell you what they mean, or whether they would stop a file rendering properly on the Internet Archive. It may be that 0002 has an alpha channel that isn't present in 0000. But I'm speculating wildly...

     

    Yeah, I wouldn't know what those mean either. I should find an ExifTool for Windows so I can peek at what you mean.

    Thanks so much for replying!

    Affinity Photo 1.8.573 (The attached samples were processed in 1.84.)

    Windows 10

    I've been scanning and uploading data to the Internet Archive without fail until very recently. Basically some scans don't render properly there. I know someone there and they are perplexed. I don't necessarily think something is wrong with Affinity Photo or IA, but rather my processing of the files.

    Typically what I do is:

    1. Open the file
    2. Use the crop tool to rotate and crop the file.
    3. Save.

    Sometimes, if I have two-up, I'll do this twice. Usually if I do this, I export out to TIFF.

    I've attached two. 0002 doesn't render on IA. 0000 does. I imagine the sizes are different but IA can handle that.

    Aside from sizes, can anyone see something else that's different such as attaching an ICC profile or maybe a layer or something. I know it's just a TIFF and I'm just going to rescan, but I'd like to know if there's something I can do differently.

     

    Also: I'd like to know... I am scanning material that often comes out rotated on the scanner and I'd like to rotate them. I usually use the crop tool to do that:

    1. Turn on crop.
    2. Rotate with mouse.
    3. Enter to apply the rotate.
    4. Turn on crop.
    5. Crop image.

    Is there a better way or is that way just as good as any?

     

    Thanks for any help!!

     

    Cheers,

    Mike W
