------- Additional comments from [EMAIL PROTECTED] Sun Mar 16 08:51:39 +0000 2008 ------- @discoleo "1.) DPI and LPI are printer measures" I strongly disagree with this statement in the context of a bitmap export. You have a print-oriented view, but this bug is not about printing it's about exporting to a file so the target are other computer programs not just printers. For a computer program "DPI" (as used both by proprietary programs such as Visio and FLOSS programs such as the Gimp) is the ratio between the image dimension in pixels (pixel being the basic bitmap unit) and the image dimension in inches (physical unit, used to measure other parts of the document). Without LPI does not exist in this context. It may be relevant for printers but not at the computer stage. So when you resize a bitmap or export to a bitmap file, you need to display three sets of values 1. the image size in pixels 2. the image size in physical units (inches or millimeters depending on the locale) 3. their ratio in DPI Changing 1. changes 2., changing 2. changes 1., changing 3. changes 2. The user can follow several strategies to select the DPI value: 1. size the image "as on-screen", using the DPI ratio of his current screen (Current OO.o strategy. Unsuitable for many usages but valid in some contexts 2. size the image for a generic streen target, using common screen DPI values such as 75, 96 or 100 dpi 2. size the image with a print target in mind, using common print DPI values (150, 300, 600) 3. just cram the maximum number of pixels into a specific physical size, avoid any dithering in the current program to preserve pixel info, rework the bitmap in something else. This will result in very strange one-of-a-kind DPI values but is a valid use-case newertheless --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
