Apache OpenOffice (AOO) Bugzilla – Issue 85451
image scaling not uniform even when Keep Ratio set
Last modified: 2017-05-20 10:06:11 UTC
image scaling not uniform even when Position and Sizing, Keep Ratio is checked this defect makes it hard to rescale images without introducing distortion the Keep Ratio box should not remain checked if image aspect ratio has been changed from the original once that capability is restored, a good check on the feature would be to have proper aspect ratio restored if the Keep Ratio box becomes checked
In my mind this is not a bug but an enhancement.
understood.. i'm thinking more strictly as a bug. rationale: it is hard to tell on the screen, after scaling down (or up), whether or not you have maintained the proper aspect ratio. this distortion has mangled some of my content, and it is only (and hopefully) caught after hi-quality printing when the error becomes evident. since the user can't determine whether or not their operation of the software has caused a content error, i believe that this problem is best considered to be a software error. anyway, FYI. please label it however you think best, just wanted to ensure that the impact of this problem is understood. thanks for your efforts.
my previous post was focused on the practicality of the workaround. more precisely: checking the box does not perform the labeled function and has no apparent effect. that is a bug.
[Dee Pizzica 6/3/08] I was able to recreate this issue in the 2.4.0 release of Impress (XP Pro OS) I wish to add on to brutzman’s comments about why this is a bug that will negatively effect users. In addition to a user expecting the “Keep ratio” checkbox to maintain the proportions of the selected image, this is a feature present in MS Powerpoint (ver 2002 SP3). In Powerpoint a user can right click on an image, select format picture and on the size tab check the box to “Lock aspect ratio.” When a Powerpoint user attempts to drag the corner of an image to resize it, the resizing does force the image to maintain its proportions. In Impress in order to maintain image ratio, the user must open the Picture and Size menu and adjust the values in the Width and Size fields in order to resize their image. Because these adjustments do not occur in real time, the user must save changes and then potentially make additional adjustments.
I must not understand the problem. Here's what I see in OOo 3.04 beta. 1. I create a new presentation 2. I add a graphic to the page (a jpg picture) 3. select the picture 4. Select Format | Position and Size to get the Position and Size dialog 5. Click "Keep ratio" 6. My particular width and height are 4.84 W and 4.61 H. If I change values **in this dialog**, the ratio is preserved. For example, if I change 4.84 to 5.84, the height automatically changes to 5.56. Therefore, this feature works (so far). If I try to manipulate the image directly by grabbing a handle on the image and dragging it, I can resize the picture any way I want, creating distortion. The ratio is not preserved. Is this the "bug"? I then do the same thing in PowerPoint 2007. 1. New presentation, copy the picture from OOo and paste into powerpoint page 2. with the picture selected, click Format, click size to bring up the Size and Position menu, and height and width are at 100%, click lock aspect ratio if not already checked. 3. change Height and width changes (in the height / width boxes on this dialog). Similarly, change the scaled height (100% to 110%) and scaled width changes too. 4. close the dialog, drag the middle handle to the right to stretch the picture lengthwise, bring up the dialog and even though lock aspect ratio is still stretched, my height is now 100% and my width is 126%. So OOo 3.04 behaves essentially the same way as Powerpoint 2007. If the goal is compatibility of the two products, then this behavior is a feature, not a bug.
Pressing the SHIFT-key while sizing keeps the Ratio, too (as a workaround). Changing to enhancement.
i too would like images to be resized keeping aspect ratio w/o need to press (and hence know about) SHIFT key, because most probably a user doesn't want to distort an image. also this is the way powerpoint behaves. If you want to keep the old behaviour available, then please change it to use e.g. ALT key.
Still here in 3.3dev I don`t agree that it`s just an enhancement: There is a checkbox with a described function presend, and it does not do anything. Enhancement could be removing non-functional elements like visual trash, but we do want it working!
Hi, I ran into this issue running writer 3.2.0 under XP, pasting from an Paintshop. If the page formatting constrains the size of a graphic, say it is too tall for the page at the native size, even if "keep ratio" is checked, the image aspect ratio is distorted before the "picture" dialog box can be open. The original aspect ratio is lost and cannot be recovered except by going back to the source and resizing it. The "shift" key trick doesn't help because the damage has already taken place. As another user noted, I did not notice the distortion until I printed the file, and lost a lot of time recovering from it. This is definitely a bug, I'm appalled that anybody is chewing up time arguing about it.
This definitly is a bug. A normal user will not understand nor like the standard behavior of Impress when rescaling an image with the mouse. Please let the aspect ratio stay fix as default behavior. PS: My wife just stopped using Impress and went back to Powerpoint after she tried to create a presentation with a lot of photos in it... Please change the status from UNCONFIRMED to something else, it definitly still happens in OOo 3.2.1.
Please specify steps to reproduce bug.
