Image quality RRS feed

  • Question

  • Hi

    I have a problem

    I have create a vettorial path.

    Now i want to obtain an image from this path.
    Therefore i go to object/image/create image object,
    set to 200 dpi,
    i select the area:

    but the image is low quality.
    This happens with all value of Dpi.

    Then when i import an image high quality in artboard,
    the image becomes low quality.

    It happens to you also?

  • raising the value of rasterized area
    the quality of the image make better
    but anyway it is of low quality

  • I get good results with the Create Image Object feature when I bump the dpi to it's maximum, which is 300ppi.

    The zoom level is kind of tricky in Design. In the lower left corner of the interface is a zoom pop up menu. You should set this to Actual Pixels which gives you a true view of your artwork. But sometimes when we import images, or create image objects, the zoom level will jump to a different value. Be sure and check to see that it remains at Actual Pixels. However, this has no effect on image output, such as saving or exporting the image.

    Another thing that is sort of tricky in Design is that it defaults to 96ppi resolution. When you use the Create Image Object feature, setting the ppi (dpi for those who prefer that term) also doesn't affect the export or save resolution. After you create the image and choose File > Export, make sure you specify the resolution you want to export.

    Try this: after you import the image, choose File > Document Size and set the resolution to match the resolution of the image. Then make sure the zoom level is set to Actual Pixels. And let me know if this works for you.

  • There is a problem with bitmap rendering in Design 1. I covered it on my blog and this might be your problem. It could also be the Actual Pixels problem Annie descirbed. Can you upload the actual exported graphic and the .design file so I can see what's going on? I'm curious.

  • Sure you can crank up the ppi to 300 but the downside is that you pay for it file size and you should get great quality at 96.

    I don't think that there is a doubt that the quality is not correct.

    As well as using the usual create image object, which btw I was hoping would get better in terms of useability as we did ask for some way of controlling its size other than dragging, you should try to set crop marks. This will give you more control as you can click on a start and end point or set from bounding box or actually type values in. Following on from this then just export as required.

    I have not done a side-by-side test to see if this method produces a better quality but I guess in theory it should do given that you are making a single pass rather than a double one.

    any takers ?

  • There is a new feature in Design 2 that lets you preserve the image size when increasing the resolution. Try this: Create your vector objects. Go to Edit > Options > General and make sure there's a check mark in the Preserve pixel dimensions on export. The create the image object and up the resolution to 500. Right click on the image you just created and choose Export. The image should be of good quality but the dimensions should remain the same size.

  • How about the new bitmap slicing in Design V2? Does the quality of bitmap slice look better? You can also setup the output bitmap dimension in slice properties, easier than controling the ppi IMHO.

  • The bitmap rendering in Design 2 is quite impressive (so nothing like Design 1). I haven't done extensive testing yet but just based on my quick experimentation I'd say it's on par with PhotoShop. You can read my initial thoughts on the new Design 2 here.
