Blurry PDF pages due to small image sizes

    • when a pdf comes out as blurry, it is most likely due to the fact that the full image size is less than the 1200 x 1200 iiif image api call. this results in blocky text, as the pixels are blown up 2X or more to fit the screen.
    • redepositing the jp2 so that the full image is larger than 1200 x 1200 px when rendered into a jpeg will fix the issue, if redepositing a larger size jp2 is possible.
