  • Illustrator and Image Size (Raster Image)

    Posted by Steve Wilson on May 10, 2016 at 6:43 pm

    Hello

    I’m a limited user of Adobe Illustrator CS6. I use it for my whiteboard animation. Basically I use it to help it draw the image properly.

    I have a concern that i have addressed before but I never found a solution. It could be because I did not explain it well.

    Basically the concern is when I open a Raster Image in illustrator it does not open at the image size.

    Since I’m not sure I’m explaining what I mean, I decided to do a video and hopefully someone will take a peek (its around 40 seconds long) and give me an explanation or solution to why the raster image opens smaller than the actually image size (because the image opens smaller it looks blurry in the whiteboard video)

    Watch video please and I will show you want I mean.

    Any thoughts, solutions or recommendations, would be appreciated.

    Thanks

    Illustrator is using the Document Size of the image, not the Pixel Dimensions, I think.
    Examine the image in Photoshop’s Image Size window.

    Thanks for the quick reply.

    I’m not sure what you mean but the image size in PS is 974 x 1200. The same size as I showed in the video.

    Here’s what I have in CS4..

    It provides the ‘Document Size’. I’m not sure how to expose that value in your version. Perhaps it’s available in the Height/Width dropdowns.

    ..Maybe the ‘Dimensions’ drop-down menu.

    Sorry, I guess I don’t understand. You are showing the same size as I am. I’m not sure how this relates to my AI question. Sorry, confusing.

    If you have two raster images..
    A – 1px X 1px, 1ppi. The document size is 1 inch and will display as 1 inch in Illustrator.
    B – 1000px X 1000px, 1000ppi. This will also display as 1 inch in AI.

    An inch is always an inch, but the actual size of a pixel can vary.

    Knowing the pixel dimensions of an image does not tell you it’s size, you also need the PPI.
    To your original question, it is opening at the ‘original’ size.
    Your 974×1200 @300ppi image is 3.25″ x 4″.

    The pixel dimensions that Illustrator is reporting are relative to the settings in that AI project file. It’s not reporting the rendered pixel dimensions of the raster image, unless you Object/Rasterize after the object is properly positioned.

    The blurriness you’re seeing is partially due to Illustrator not actively rendering artwork on the screen the way Photoshop does. Photoshop renders constantly. Illustrator can’t because it can easily use too much memory.
    All that matters is how it prints or exports.

    thanks for trying…but I don’t get it. Everything is in pixels…both photoshop and illustrator.

    If you are working in a 800×600 Web default AI project..
    When you place a raster image into Illustrator the placed image will be it’s Document Size, the pixel dimensions don’t matter in themselves. It’s pixel dimensions and PPI.

    Illustrator / Preferences / Units / General.. If you want to see inches.

    My thinking is that you simply want the placed image to be 974×1200.
    Just click the image and adjust the size in the Window / Transform palette.
    The will not appear as crisp as it does in Photoshop, but it will print and export fine, as long as you’re not making the raster image larger than it’s original size.

    Object/Rasterize in AI didn’t do anything. Sorry, I didn’t explain bhit, but it is blurry when I export it. The only time the image is not blurry and the right size is when I don’t use illustrator. Illustrator setting is all setup for pixels, not inches.
