António wrote: > Is there any other suggestion on resizing PNG output > without loosing image and barscale? fundamentally if you want to have full cartographic control or want to make a high-res image suitable for e.g. a poster or a journal article, you're going to have to use ps.map. (now made easy with Anna's new cartographic composer) you can convert .eps or .ps to PNG if you need to with a number of tools, here is one way: pstoimg -aaliastext -antialias -depth 24 -scale 1.5 $IMAGE.ps d.barscale's height is hardcoded at a fixed number of pixels high in display/d.barscale/draw_scale.c as it was only designed to be shown on a computer monitor or projector at 100% scale. maybe 'd.barscale -l' does not look so bad when made (relatively) small?

Re: [GRASS-user] Problems while running d.out.file
Hi Sorry to get back to this question again but I was not able to solve this. Ok 1- I have plotted my raster 2- I have added a command layer with this d.barscale bcolor=none at=0,90 3- If I use the "Save display to graphic file" functionality it works just fine. But If i try to set a smaller Width and Height: a) if I place barscale at 0,90 it gets cut b) If I place barscale at 0,0 it does not get cut but barscale gets over the image Is there any other suggestion on resizing PNG output without loosing image and barscale? Another question: when I launch a new Map Display window: Is it possible to define its size? Thanks Antonio Hamish wrote: Moritz wrote: I can confirm the issue (António, have you posted a bug report ?). The problem is not that the scalebar "disappears", but that its location is not adapted to the changed resolution: see the http://geog-pc40.ulb.ac.be/grass/export_png/ for a series of examples. I'm not sure I fully understand the problem, but d.out.file has always worked well for me. the effect of making the width and height of the image is the same as dragging the xmonitor window bigger- the barscale and text is still the same size when viewed at 100% scale. when shrunk to fit on the screen in an image viewer it becomes tiny. You can make text and line widths bigger to compensate but really if you want things to scale well e.g. for a hi-res poster image, you should probably be using ps.map, not screen dumps of the Xmonitors, as the d.* modules were designed for. barscale and legend are placed as a percentage of the display frame, so at least their relative position should stay intact even if the frame gets bigger. if y'all think there's a bug please file a detailed ticket with the steps to reproduce using one of the standard datasets, and I'll look into it.

ok, so in the wx Map Display window click on the
"save display to graphic file" icon on the right
side, pick a width and height for your output image
(or a template size), select a filename and image
format to use, and [Save].
to explain to the list, the legend and scalebar
as provided by the wx map display "Add map elements"
icon ("elements" = "decorations"), overlay the main
map composition like a slippy sheet of overhead
transparency plastic with an image on it. You can
then drag the overlay over the background to re-
position it.
but when you export the map composition the overlays
don't get the memo that they should be propor-
tionately place themselves not simply as a fixed
offset from the bottom-left corner. (? I'm not
exactly sure how the overlay positioning works, but
assume that's what's happening)
The quick work-around is for the user to use d.legend
and d.scalebar as "command layers" in the main map
layer wx gui (somewhat hidden under the "add grid
or vector labels" icon) with manual command line
controls. Then the legend or barscale gets rendered
directly as part of map rendering, not overplotted
as a movable overlay.
(seems like the 'add command layer' could use some
work as getting it working was a little brittle,
but that's a matter for another wish ticket..)

I'm not sure I fully understand the problem, but d.out.file has always worked well for me. The original issue I responded to above is not with d.out.file, but with the equivalent option in the wxgui Map Display window. The fact that there is this issue forced António to use d.out.file which then causes the problem the subject line refers to [1]. So, the bug is not with d.out.file, but with the wxgui image export feature.

Re: [GRASS-user] Problems while running d.out.file
Hi Hamish THe problem is with the "shrink". You are right it's tiny but in the case of the scale bar it is not shrinked. I mean it keeps the original size. Example: This is the original http://s1183.photobucket.com/albums/x462/toyzerocha/?action=view¤t=original.png This is half of the size http://s1183.photobucket.com/albums/x462/toyzerocha/?action=view¤t=Half_size.png In this is case it does not disappear it's just cut. I would report this as bug. Or not really? Antonio Hamish wrote: Moritz wrote: I can confirm the issue (António, have you posted a bug report ?).
