Sounds like a reasonable feature, though I do not know how difficult to implement. |
|

I think this would be good to have, too. At work we use 300dpi colour and greyscale and 1200dpi mono images, for example. We'd need to consider at least: - Colour - Greyscale - Bitmap/mono with the last two possibly being tinted / have a spot colour applied. |
|
|
I also agree it would be good to have. This is either a candidate for PDF output options or an additional Preflight flag (or both). |
|

It is necessary for pro work to specify a high line-art resolution. There should be 2 resolution boxes instead of one: Downsampling: Line-Art (600 dpi) Greyscale/Color (300 dpi) |
|
|
i'm for a preflight warning if resolution if an image is above a DPI defined in the settings... |
|

@ale a warning is great, but (controlled) downsampling with different res. for line-art, greyscale and color is time-saving & better. Consider a newspaper with 24 pages and 6 pics on each page. That are 144 pics to work on. No one wants to do this manually. That should be a wholesale config option in PDF Export settings, together with an override maximum DPI setting for an individual picture (as it is done in other dtp's). |

any idea how to tell scribus that your picture is a grayscale, line-art or color one? should it detect it automatically from the file characteristics at preflight and export time? |
|
|
@ale - auto-detect at import time from file characteristics - jpeg 24bit, tiff,png >9..24bit -> always color (default) - jpeg 8bit, tiff 8bit, png 8bit -> always grayscale - png, tiff: 1bit ("tiff bilevel image") -> always lineart - write it as a property in the picture manager dialog - make it editable there so user can change from the lo-res color default to higher res grayscale or lineart - for simplicity, grayscale may be left out. |

@ale Recently I started to use gs, read in the docs that it can detect color/gray/color images on its own. You can set dpis globally for these. Taken from Ghostscript docs http://www.ghostscript.com/doc/current/Ps2pdf.htm there are these 3 switches: -dColorImageResolution AAA (dpi) 300 is Default for printer -dGrayImageResolution BBB (dpi) 300 " " -dMonoImageResolution CCC (dpi) 1200 " " It seems that bug is fixed - with those extra gs commandline options and - 3 extra inputfields in scribus printer dialog |
