Eyal Rozenberg <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |libreoffice-ux-advise@lists | |.freedesktop.org Keywords| |needsUXEval --- Comment #1 from Eyal Rozenberg <[email protected]> --- (In reply to Jérôme from comment #0) > Interpolation algorithms (None, Bilinear, Bicubic, Lanczos) require a > minimum set of pixels in the vicinity of each pixel to be interpolated Well, yes, but we have that minimum set. Unless you're talking about resizing 2x2 or 3x3 images? > without perceptible loss of quality. Compression very often involves perceptible loss of quality. If you're suggesting LO offering some estimate or indication there might be a perceptible loss of quality, please say that. > I propose that this dialog get a new field like "modify the old resolution > only if the new one is less than" : [r]. > The default "r" ratio could be 50%. > > If you set 1000% for the "r" ratio with a 500 dpi old resolution and 600 dpi > new resolution, it will transform the image with a 600 dpi resolution. > > If you set 50% for the "r" ratio and a new resolution to 200 dpi : > A. a 500 dpi old resolution will be changed into 200 dpi (because 200/500 < > 50%) > B. a 300 dpi old resolution will be unchanged (because 200/300 > 50%) > > In the B case, it prevents a loss of quality (because of interpolation > algorithms). > > In the B case, you can still use this dialog box in order to convert an > image from one format to an other (but the resolution will remain the same). In this dialog, the user says what they want: They set the new resolution. I don't understand how a "please second-guess me and ignore what I asked" control will help. Please try to justify this proposal further. -- You are receiving this mail because: You are the assignee for the bug.
