 Posted: Tue Jun 17, 2014 10:19 am Post subject: Export image of %pl or %dw |
 |
|
Greetings,
I have an application using Simpleplot and would like to export the plots preferably as PNG, or any other format, whatever is possible. I tried using create_graphics_region@/select_graphics_object@ in combination with export_image@, but I couldn't get any useful results.
Is it even possible to export from Simpeplot, and if so, how? |

create_graphics_region@ and select_graphics_object@ relate to %gr only.
If you only need to do this a few times for your own use then just use the Print Screen key on the keyboard and paste in Microsoft Paint. |

| Unfortunately I'd need an automated way of exporting the plot. So you say it's not possible? |

I cannot think of a way to do this. Maybe you should try using %gr instead of %pl.
There will be lots of alternatives and perhaps others can advise. |

You have two options using the Simpleplot subroutine DEVNAM (=device name):
a) if you like to use %pl, use it but with [user_drawn] option and Simpleplot_redraw@ subroutine | Code: | Program simple5
use mswin
INTEGER winio@,i,StartCB
EXTERNAL StartCB
i=winio@('%sy[no_border]%ca[User drawn]&')
i=winio@('%pl[user_drawn]&',800,800)
i=winio@('%sc',StartCB)
END
!--The start-up callback
INTEGER FUNCTION StartCB()
use mswin
INTEGER N,i
PARAMETER(N=101)
REAL x(N),y(N)
!--Create the data.
DO i=1,N
x(i)=i-1
y(i)=x(i)**2
ENDDO
!--Call SIMPLEPLOT routines to plot the graph.
call devnam("windows_metafile")!shows in screen and creates a wmf file
call picpos(4.0,5.0) ! locate the graph in the page so that everything enters
CALL TITLE7('centre','Centre','Sample for Dan')
CALL SCALES(0.0,10.0,1,0.0,100.0,1)
call thckmg('LINE',1.0) !thickness of lines
CALL NEWPIC
CALL TITLE7('t','Centre','Sample')
call textmg(1.5) !size of the text
call axsbtk('XC','I') !ticks inside for x axis
call axsbtk('YC','O') ! ticks outside for y axis
CALL AXLBJS('**', 'Centre') ! labels centred
call chset(8) ! character set
call cvtype(ctype) ! curve type
call thckmg('LINE',3.0) !thickness of lines
call pen(4) !pen colour
CALL AXIS7('XCartesian','x-axis')
CALL AXIS7('YCartesian',' ')
CALL AXLOCN('YCartesian', 'Following') ! locate a new y axis on right
call axlban('yc','O') ! tick labels towards the outside
call axsbtk('yc','O') !ticks outside for y axis on the right
!call axclr('yc',1)! only axis is drawn without ticks if you prefer
CALL AXIS7('YCartesian','y-axis')
call axis7('YC',' ') ! draw the new y axis without title
CALL AXLOCN('XCartesian', 'Following') !locate a new x axis on top
call axlban('xc','N') ! no tick labels
call axsbtk('xc','I') ! ticks inside
call axis7('XC',' ') ! no axis label
call thckmg('L',1.0) !line thickness = 1
call pen(2)! colour red
CALL BRKNCV(x,y,N,-1)
CALL SIMPLEPLOT_REDRAW@
StartCB=1
END |
2) or use Simpleplot routines directly
| Code: | program Simpleplot_plots
!requires simpleplot.dll
implicit none
real*4,dimension(70) ::xarr,yarr
integer*4 :: narr,ltype,xscale,yscale
integer*4 :: ctype,i,ans
character(8) :: xlabel="x",ylabel="y"
real*4 :: minx,maxx,miny,maxy
narr=0
do i=1,70
xarr(i)=2*i
yarr(i)=i*i
narr=narr+1
end do
!call devnam("window") !screen only
!call devnam("windows_printer")! prints directly to the default printer
!call devnam("windows_metafile")!shows in screen and creates a wmf file
call textmg(1.5)
call axsbtk('XC','I')
call axsbtk('YC','O')
call thckmg('L',2.0)
CALL AXLBJS('**', 'Centre')
minx=minval(xarr)
maxx=maxval(xarr)
miny=minval(yarr)
maxy=maxval(yarr)
xscale=1;yscale=1
CALL SCALES(minx,maxx,xscale,miny,maxy,yscale)
call axcrss('YC',minx)
call pen(2)
ltype=0
ctype=3
call chset(ans)
call cvtype(ctype)
CALL AXES7(xlabel, ylabel)
call pen(1)
call title7("t","c","A Simple......Plot")
call pen(4)
CALL BRKNCV(real(xarr,1),real(yarr,1),narr,ltype)
call endplt
end program simpleplot_plots |
Hope this helps,

| Thank you very much aebolzan, this seems to be exactly what I'm looking for. I'll try it out. |

If you can get a handle for the %pl window, you could probably get a snapshot from the window using something like (untested code and in MiniBASIC-syntax):
| Code: |
HDC hdc = GetWindowDC(hwnd)
if hdc
HDC hdcMem = CreateCompatibleDC(hdc)
if hdcMem
RECT rc
GetWindowRect(hwnd, &rc)
HBITMAP hbitmap = CreateCompatibleBitmap(hdc, rc.right, rc.bottom)
if hbitmap
SelectObject(hdcMem, hbitmap)
PrintWindow(hwnd, hdcMem, 0)
' Here do something with the bitmap or memory device context
' Save bitmap into file maybe?
DeleteObject(hbitmap)
endif
DeleteObject(hdcMem)
endif
ReleaseDC(hwnd, hdc)
endif
