: Save for Web in Photoshop with custom DPI I am writing user documentation using DITA which allows me to easily generate deliverables in PDF, CHM and web formats. The images need to be saved

@Cofer715

I don't have any experience with it, but from the docs:


Some bitmapped image file formats store a dots-per-inch (dpi) or other
resolution values. FOP tries to use this resolution information
whenever possible to determine the image's intrinsic size. This size
is used during the layout process when it is not superseded by an
explicit size on fo:external-graphic (content-width and content-height
properties).


( apache fo docs )

So try setting the content-height and content-width explicitly.

Also: imagemagick has a -density switch to alter the DPI flag without resampling

( imagemagick docs )

Unfortunately, Scott is right. Adobe has continued to leave the ppi at 72. This is a big limitation in the face of device proliferation. The concept of device central showed that Adobe had their head in the right place but they haven't kept pace.

One work-around I've used for multi-resolution output can be done in the Save for Web dialog. If you're working with vector art or source raster info in high enough resolution, you can resize the art on export with the image size settings. The ppi value will still be 72, but you can theoretically get your pixel dimensions right. A simple example is iOS devices that require an @2x version: Just scale up to 200%.

There's no method for altering the default PPI of Photoshop's Save For Web command. As you've discovered it's set to 72PPI (might be 96 on Windows).

The only way I'm aware you can get altered PPI png or JPG images is to use the Save As command, as you've discovered.
