Re: imdisplay command line parameters

good ideas. When on cygwin can or can not be present an Xserver. When not present 'display' should redirect the output to native GDI lib. A strategy can be sense the $DISPLAY, if not defined, go for GDI. And go for GDI always when win: output is specified, is this intended for this ? On the other si...

Re: imdisplay command line parameters

Can imdisplay take a image via a stdin? If so you can do something like convert image.png -thumbnail 640x480 png:- | imdisplay - tested, seems 'imdisplay' ignore the stdin. I tried: $ convert gpib488err1.PNG -thumbnail 640x480 png:- | imdisplay - no errors, but open 'imdisplay' with nothing display...

Re: imdisplay command line parameters

sure the 'imdisplay' binary isn't packaged with Cygwin IM package. Work on my system because I have both Cygwin and native Win32 ImageMagick. So this is not a good choice as alternative to 'display' on Win32 system without the Xserver. As simple viewer the Windows built in is good, but as you need s...

where 'imdisplay' process the arguments?

hi, as 'imdisplay' arguments are not documented, I'm trying to understand them by looking at the sources. Strangely the unix sources doen't contain the IMdisplay.exe related files, and so isn't possible to crosscompile this file with: ./configure --target=i686-pc-mingw32 & make So I downloaded t...

Re: imdisplay command line parameters

you may need to use convert to do your image operations then use "imdisplay" to display it. I am not certain of the syntax of the windows "imdisplay" command - sorry. converting to a temp file with convert on Win32 platform work as expected, but add overhead. About imdisplay, I ...

imdisplay command line parameters

hi, I'm writing a crossplatform bash script, on Windows I use cygwin. As the target PC has no Xserver, when on Linux I use 'display', on Win32 I use 'imdisplay'. The problem arise using command line parameters, as 'display' support lines so: $ display -resize 350x90 image.png while I'm not able to u...
