My dashboard has a number of images. The images themselves are quite large at 2474 pixels by 1236 pixels and are very clear. However when I shrink them down they become blurry and pixelated and it's especially noticeable when printing it to PDF or paper. Is this a Tableau issue that I need to be aware of or am I doing something wrong such as shrinking them down to the wrong ratio?
Could you please share some sample mock up in packaged workbook (.twbx format)?
We need some more information, like are you using any image object in your dashboard or using image in a sheet?
What is the (resolution width X height) size of your dashboard or your image object?
