Adobe resize image
Which is strange because although people think of Photoshop when they're generating images, in design is much faster and more appropriate for multiple page layouts, image replacement, etc. It's like a Cadillac in Photoshop and pinto in indesign. I'm just really surprised that indesign does not have more custom export settings. To have a document that didn't have one of these dpi's to match it's lpi means you have no guarentee how it will resolve. You print at 300 dpi (less depending on your lpi), you display on the web at 72 dpi, and retina at 150. While I understand that web browsers would likely resolve a dpi lower than web quality (72) or retina quality (150) to display the dimensions I want, that's just not the way you do it. No, I was trying to find a way to change the pixel dimensions, not the ppi. For that I might as well just use a photoshop batch to re-size, which I'm already doing. To follow your method I would have to calculate what dpi reduction would turn my 4700 pixel document into a 2048 one, and then I would have to go back into Photoshop anyway and change the dpi back to 72 while keeping the dimensions the same. I need to keep 72 dpi, and reduced from 4700 x 4700. I want 2048x2048, jpg usually, sometimes a png. I've been using adjust layout for a number of years and I guess that I've never used it on non-visible layers? I don't see how that's possible. This would be a super massive enormous failure on Adobe's part if that's true, unless someone here has a solution I'm not seeing online. I thought I could use adjust layout but apparently it will not adjust anything that is hidden-which makes sense by default but I am not seeing any toggle anywhere to include all of my hidden images and layers. Most importantly, I don't want to mess up the placement of all of the thousands of images already in the document. However, I am wanting to change the overall pixel dimensions of the document at this point, because I realized I don't need nearly as a higher resolution as I had thought originally, and therefore to make for easier export without having to resize afterwards in batch or separately (or forget). In the end it means that I have some single layers with 60 or more image fields, each hidden after exporting. I do this because it is so easy to swap out an image in InDesign compared to Photoshop and it's heavy duty layers and exporting is fast. I have my background image on a horizontal and vertical page and all products are placed images within a layer representing a product category.
This is because I have used my InDesign document to export product images for my website. Entire layers are turned off from visibility but also every single placed image field other than the one on top is hidden from visibility. I have an InDesign document with around 100 layers, each with 5 to 50 objects within the layer.
