If you want to insert an image in a text document, then it is very wise to prepare that image in image editing software (Photoshop etc.), to give it the dimensions and resolution (in dpi) that you want. That way, you can insert the image as-is, and you don’t have to use Writer to modify its properties. I recommend Affinity Photo for this purpose, it is cheap, and functionally comparable to Photoshop. You also get free updates. Back to the problem. An image has a size in pixels, but not in cm or inch. The dpi setting in the Exif header will tell software like writer how big the image should be in the document. This dpi setting is just a kind of comment, comparable to your name in the header as copy right holder. If you change the dpi setting, the size of the image on the page will change obviously, but (and this is important) nothing is done (or should be done) to the image itself. Often the dpi setting in the Exif header is 72 or 96 dpi, camera’s will add that setting. It is a rather silly setting. Now, what should happen if you insert a picture that would be to big for the page, let’s say that with the dpi setting in the header, it would be 20 inch of 50 cm wide on a page with 17 cm between the left and right margin. Should Writer keep the dpi setting, and reduce the number of pixels in the image to get the image fitting between the margins? NO, NO, NO !! Writer should change the dpi setting, and leave the image itself untouched. Further manipulations with the size (in inch or cm) of the image on the page, should also just change the dpi setting. When you’re finished with these manipulations, then you should have a look at the resulting dpi setting. Let’s say it is 1000, that is a rather silly dpi setting for a printable page. Then you can reduce it to 300 dpi (for instance), and Writer will recalculate the number of pixels and actually change the number of pixels. What if an image has no dpi setting in the header? Simple, let Writer fit it between the margins, and let it calculate a dpi setting. Remember, the dpi setting is just comment in the Exif header. Then adjust the size of the picture, and when you’re done give it the dpi setting you require and let Writer recalculate the pixels. In other words, I don’t think adding ‘just’ a dpi setting of for instance 200 dpi is the best solution for your problem.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
