File with the same graphic inserted twice
I checked "blurred graphic.odt " with "Ooo 3.0.0 (DE) Multilingual version German UI WIN XP: [OOO300m9 (Build9358)]" and can not see any difference between the 2 images. @uwegalle: Please attach a test kit with images, commented screenshots an contribute a step by step instruction. Both graphics in the attached document look blurred, because they are resized with non-equal aspect ratio. The graphics are not really cropped as Uwe initially assumed. Resizing them to original size, they will both look good again. Closed. No bug here. Created attachment 59527 [details]
another file with the same image with clearly different appearance
I am stunned. I am using exactly the same version as Reiner Bielefeld wrote so the version cannot explain a difference. I attached a second file what it makes clear to everybody that the two graphics look different. Can you really not see a difference here? I will use this case to ask the community, I am sure that everybody can see a difference between the two graphics. In "blurred graphic 2.odt" I again see 2 completely identical, vertically crushed images. No new information! Vista-specific? Specific to uwegalle's PC? @uwegalle: It would save much time if you could contribute requested additional information (test kit with images, commented screenshots, step by step instruction) instead of already known information again and again.

Original graphic
I realized that graphics are differently displayed dependent from the font size of the operating system. I don't work with the standard font size of 96 dpi but with 144 dpi. With this font size my screen width is filled with an A4 page scaled to 100%. Now I switched to 96 dpi what should also be your font size. With this font size I also do not see a difference with files created with a Windows Vista font size of 144 dpi. I am attaching 3 files: 1) Another odt-file created with a Windows Vista font size of 96 dpi containing two instances of the same graphic. Now you really should see a clear difference. 2) A screenshot how it looks on my screen. 3) The original graphic as png file so that this graphic can be inserted on your computer. On my computer the problem is visible with both font sizes. step by step instructions: I suppose that it is known how to open and view an odt file in Writer and a screenshot in a graphic editor. If you even cannot see a difference in the screenshot please enlarge the file at least to 300%. Now really everybody should see a difference between the two graphics. You can create this difference for yourself by using the third file. For this file open writer and a new document. Open the "screenshot 96dpi.png" in Paint. Copy the graphic into the clipboard. Paste it into the new Writer document with Paste special / Bitmap. Press esc. Press Enter two times. Paste the same graphic a second time into Writer with Paste special / Bitmap. Double click on this graphic. Resize it a little bit by setting left to 0,02 and bottom to 0,02. Press OK. On my computer the graphic is blurred now. Perhaps I will hear the next objection at this point. mru replied to my first posting: "Both graphics in the attached document look blurred, because they are resized with non-equal aspect ratio." If he really thinks that a resize "with non-equal aspect ratio" did change the content of the graphic then this is the bug: I left the standard setting keep scale (not sure about the correct english term, it's the first radio button in the dialog) in both graphics. With this setting the remaining content of a graphic must not change at all, regardless of the settings in left, right, top and bottom! These settings must only cut a piece of the margin on the left, right, upper and down side of a graphic without changing the remainder of the graphic! The remainder of the graphic must not change even in the case that only on one side a piece of the margin is cut. Only with the second radio button the remainder of the graphic can be stretched or compressed! I want to ask you to confirm the functions of the two radio buttons because the explantaion of mru is wrong. The function of the first radio buttom is to keep the remainder of a graphic unchanged even if the graphic is cutted on one of its margins. The function of the second radio button is to stretch or compress the graphic inside the unchanged area. This radio button can explain a change of the appearance of a graphic, the first radio button cannot explain such a change! Please try the functions for yourself, despite the blurred appearance these buttons work as I described it. I can see the bug. My system: OOoDEV300m39 on WinXP with 120dpt desktop. 1. Take a new writer document and insert the picture 'screenshot 96dpi.png' 2. Open picture properties crop tab. Notice: crop 0cm, scale 100%, width 9,82cm and height4,80cm 3. Set left to 1cm and buttom to 1cm. Notice: scale 100%, width 8,82cm and height 3,80cm. OK 4. Notice the icons in the picture on the left side are cut. 5. Save document and close it. 6. Open document. Notice the icons in the picture on the left side are not cut. 7. Open picture properties crop tab. Notice: cut 0cm, scale width 90%, scale height 79%, width 8,82cm height 3,80cm The cut information is lost. Doing the same with OOo2.4.1 and unzipping the files shows: In the file saved from OOo2.4.1 there is an attribute fo:clip="rect(0cm 0cm 1cm 1cm)" in the style style:graphic-properties. This attribute is missing in the file, saved from OOoDEV300m39. First: Thank you, Regina, for taking this issue. Second: The bug described by you I cannot recreate on my Windows Vista Home Premium SP1 computer. The cut information ist not lost in my file. I don't know where you found the attribute information but the icons in my graphic are cut after reopening the saved file. The scale is still 100% for both width and hight, the cm values the same as given by you. It seems that this is a XP issue. My problem is another one. After cutting the graphic as described by you the graphic on my computer is blurred. I switched to 120 dpi and followed each step described by you and can confirm the sizes in cm given by you. I attach a graphic file where I combined two screenshots in one file so that you should see the difference with a glimpse. Please look especially on the second lines with the small font. With these lines the difference is really clear. Please post if you can see this difference. Created attachment 59565 [details]
two screenshots in one graphic file
It is OK in OOo3.0 and OOoDEVm37. I haven't got a m38 to test it there. What do you mean with "It is OK"? Do you mean the bug determined by you concerning the loss of the cut information? What about the change of the appearance of the resized graphic? Can you see it? I repeated your steps and ended up in a blurred graphic. It should be the same on your computer. Please let me know how it looks for you and, if you cannot see a change, post a screenshot. Can you see a difference in my screenshot? > My problem is another one.
Yes, you are right. I now understand your problem. And yes your last screen shot
shows it. I will submit a new issue, for the crop problem I have found.
If you insert the picture twice from the clipboard, it is stored only once in
the document. Both places are then linked to that picture, but have different
information about size. And in my tests in that information is a difference. For
example the first one, which I had not touch, has got the information
svg:width="9.821cm" svg:height="4.805cm"
But the second one, which I had cropped, saved, load and then set back to
"original size" has got the information
svg:width="9.82cm" svg:height="4.8cm"
That is a little bit different. Perhaps that leads to the blurred appearance?
MRU->OD: I do not know which developer is the correct reprsentative for this issue, so could you please reassign if not yours? Thanks! You have to take attachment "blurred graphic 2.odt", copy the first graphic to clipboard and paste it lower in the document. Then you can see that it is slightly blurred compared to the original graphic. But the issue is not restricted to the case of using the same graphic twice in the same document as it sounds in the last two postings! I only used the same graphic twice because this makes the difference between the graphics better visible. You can open a new document, take nearly every graphic file, paste it into Writer using Paste / Special and cut it a little bit on the left or right or on the top or bottom. Usual values what make the graphic blurred are 0,02 in left, right, top and / or bottom. The degree how much the graphic is blurred depends from its size. As new file test I attach the file "new graphic". If you paste this file with Paste / Special ones in a new document and set the left margin to 0,02 and the upper margin to 0,02 then this graphic is pretty much blurred despite the fact that it is pasted only one time into the document. For me a text on such a blurred graphic is not convenient to read any more. Created attachment 59604 [details]
