https://bugs.documentfoundation.org/show_bug.cgi?id=52598 --- Comment #39 from Dirk Munk --- The original problem has been resolved, Writer handles the dpi setting properly. That means that I can now prepare images with photo editing software, and just enter them in a Writer document. Writer is not meant to be photo editing software, so don't expect it to do that. Images do not have dimensions in cm or inch. Images exist out of pixels, and those are dimensionless. It is the dpi setting that will software at which size the image has to be printed. Unfortunately high resolution jpg images from cameras often have a rather silly 72 dpi as standard setting, which means that printed images would be ridiculously big. The only proper way to prepare those images for use in a Writer document is with photo editing software. The same applies to images without a dpi setting. Load these images in photo editing software, set the proper dpi setting and required image size, and recalculate the number of pixels. I use Affinty Photo for that purpose. It is an excellent program, cheap, and has free updates. -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.documentfoundation.org/show_bug.cgi?id=52598 --- Comment #29 from Dirk Munk--- In a previous comment I stated that the information is in the EXIF headers, this is a mistake, the information is in the standard JPEG headers. I've uploaded two IrFanView information headers. The difference between the two is the dpi setting in the header, nothing else. That information is used to calculate the print size in cm / inch. It seems that Writer isn't (always) capable to read the dpi setting from the header, and it then replaces the dpi setting by the dpi of the screen. This results in a completely wrong size of the picture in the Writer document. Adjusting the size in Writer results in resampling the picture, and using the wrong, mostly lower, dpi setting. It's very simple, anyone who is able to understand the way jpg and other graphic files are handled in Writer, can understand this, Please fix this problem!! -- You are receiving this mail because: You are the assignee for the bug.___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

https://bugs.documentfoundation.org/show_bug.cgi?id=52598 --- Comment #27 from Dirk Munk--- It is a problem with handling the EXIF headers. The EXIF headers contain information about dpi etc., and LibreOffice doesn't handle them properly. It is a really serious problem if you want to create high quality documents with high resolution pictures. So I'm going to raise the importance to major. -- You are receiving this mail because: You are the assignee for the bug.___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

https://bugs.documentfoundation.org/show_bug.cgi?id=52598 --- Comment #26 from Dirk Munk--- The problem is really very simple. JPEG file headers contain information about the size of the picture, measured in pixels. They also contain information about the dpi setting. The dpi setting is used to calculate the desired picture size in cm or inch, it doesn't do anything else. A high dpi setting will result in a small high resolution picture, a low dpi setting in a large low resolution picture. The dpi setting has nothing to do with the actual contents of the picture, so changing the dpi setting doesn't do anything with this contents. It is very important to keep this in mind. The problem is that LibreOffice doesn't understand the JPEG headers of at least Photoshop elements. It will not read the dpi setting, instead Libreoffice will use the dpi setting of the display. So a JPEG photo that is intended to be 10cm x 10cm with 300 dpi, will become 31.25cm x 31.25cm in Writer, because I have a 96dpi display. (300/96 x 10 = 31.25) Libreoffice does understand the JPEG headers of (for instance) Microsoft Paint. If I open a JPEG picture made by Photoshop Elements in Paint, and immediately save it again, that picture will be opened correctly by Libreoffice. However, Paint uses a lower quality compression setting, so the actual contents is changed. Mind you, not the size in pixels, or the dpi setting!! It is indeed a serious problem, because it prevents people from making high quality documents, high quality meaning high resolution images for printing etc. It can't be very difficult to solve I guess, it just needs someone who knows about these headers, and can find a fool-proof way to handle them -- You are receiving this mail because: You are the assignee for the bug.___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

https://bugs.documentfoundation.org/show_bug.cgi?id=52598 --- Comment #22 from Dirk Munk m...@home.nl --- I ran into the same problem. I prepared some pictures with Photoshop Elements, and wanted to insert them as is in a Writer document, but I wasn't able to do so. When you edit an image in Photoshop, the properties of the image will show the number of pixels (obviously) and the desired DPI setting. The two combined can be used to calculated the desired size of the image in cm or inches. Writer ignores the desired DPI setting and will always resample the image based on the DPI setting of the screen (96 DPI in my case) and the size of the image in the document. With Compress Graphic you can change the DPI setting of the image, but that seems to be not of the orginal image but of the the already resampled image. To makes this clear, the following example. I have an image of 1600 x 1065 pixels. When I insert this image on a A4 page, it will be resampled to fit the width of the page using a resolution of 96 DPI. The resulting image has a size of 642 x 427 pixels. When I open Compress Graphic I can change the DPI setting back to the original 300 DPI, but then I will get an image size of 2007 x 1335 pixels, so a resampling of the already resampled image will take place. That is not good for the quality of the image, any resampling should be done based on the original image. In Photoshop Elements there is a setting that allows you to switch resampling on or off. If you switch it off changing the DPI setting is the only way to change the size of the image in cm or inches. With resampling on you can choose any DPI and size in cm or inch. So in my opinion three things should happen: 1. Writer should use the desired DPI setting of the image if the DPI setting is in the properties of the image (and if possible). 2. If Writer needs to resample an image, it should always use the original image. 3. It should be possible to switch resampling off, and just use the DPI setting to get the desired size in cm or inches. Attached are an example image, and two screen dumps of the Photoshop window, one with resampling enabled, and one without. -- You are receiving this mail because: You are the assignee for the bug. ___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs
