Plotting and Saving results as PNG

shayansh

 Hi,

I am trying to write some code to plot a few eye diagrams and then save the result in a PNG file. I am using Cadence Version: "IC.6.1.5.500.11". What i have done is declared a variable in the outputs with the expression load("plotrand.ocn"). Inside the plotrand.ocn file, i have placed the following code. The results plot, the eye diagrams show up correctly, and they are in two subwindows just like i want it. However, when i say save the file, it only saves one of the subwindows. The PNG file does not include both of the subwindows as i want it. 

There are two other things i would like to do if possible!

1) To resize the window before saving the PNG file. I have tried the awvResizeWindow as well as "hiResizeWindow(awvGetCurrentWindow() list(0:0 1400:1050))" with no luck.

2) To remove the legend that is displayed on the side and make it display it on the "inside". This can be achieved through the menues, but i wanted to do it automatically. 

Thanks,

Shayan

hardCopy()

  • From 6.1.5.500.12 (ISR12) you can also specify these options in hardCopyOptions(). Note that ?hcUseExistingBackground doesn't currently work - this should be addressed (I believe) in 6.1.5.500.14 (a couple of hotfixes away). If you use ?hcMakeExactCopy in 6.1.5.500.12 it will save all subwindows in one image - we're also working to allow multiple subwindows to be saved into the image in other modes. Hope this helps... 

    All these options will work only for save image.

1. ?hcMakeExactCopy : To save the exact copy of plots as seen in current subwindow.
                                   Only ?hcQuality and ?hcOutputFile arguments will work with this option. 
                                   Valid values : t / nil.    
                                   Default value : nil  

2. ?hcQuality : To change the quality of image.
                      This works only for .jpeg file format.
                      Valid values : 20 to 100%
                      Default value : 85
 
3. ?hcOptimizeForWindows :  To optimize image for Microsoft Office.
                                          This option works only for 'eps' file format.
                                          For all other formats, this will always be default set to 't'.
                                          Valid values : t / nil. 

4.  ?hcImageWidth : To set width for size of image.
                              Valid values : Any positive integer value.
                              Default value : 800 pixels
   
5.  ?hcImageHeight : To set height for size of image.
                               Valid values : Any positive integer value.
                               Default value : 600 pixels                                

6.  ?hcImageSizeUnits : To set unit for image size(height and width).
                                   Valid values : inch, cm, mm, picas, pixels, points.
                                   Default value : pixels.

?hcResolution and ?hcResolutionUnits works only for bmp, jpeg, png,  ppm,  tif,  xpm file formats. For eps,  pdf,  svg these will not work.
7.  ?hcImageResolution : To set the image resolution.
                                     Valid Value : Any positive integer value.
                                     Default value : 96 

8.  ?hcResolutionUnits :    To set the units for image resolution.
                                      Valid values : pixels/cm and pixels/in
                                      Default value :   pixels/in

9.  ?hcImageAspectRatio :  To enable the aspect ratio.  
                                        When enabled, aspect ratio will let find out ?hcHeight and ?hcWidth arguments if other is not given.                                       
                                        Valid values : t / nil
                                        Default value : nil      

10. ?hcUseExistingBackground : To use the existing background.
                                               Valid values : t/ nil
                                               Default value : nil 

11. ?hcDisplayTitle : To enable displaying trace title in image.
                              Valid values : t / nil
                              Default value : t

12. ?hcDisplayLegend : To enable displaying trace legend in image.
                                   Valid values : t / nil
                                   Default value : t 
 
?hcDisplayGrids can't be set to 't' when ?hcDisplayAxes is 'nil'.
13. ?hcDisplayAxes :  To enable displaying trace axes in image.
                                Valid values : t / nil
                                Default value : t
   
14. ?hcDisplayGrids : To enable displaying grids in image.
                                Valid values : t / nil.
                                Default value : t

Arguments ?hcMakeExactCopy, ?hcQuality, ?hcResolution and ?hcResolutionUnits will not be honored for 'eps' file format. Thus, if given be ignored.

     

  • Andrew,

    I tried to add the ?hcMakeExactCopy t in the hardCopyOptions in 6.1.5.500.12 but I still only see 1 subwindow got saved. Have you tried this before? Is any other option that I can try to save all of the subwindows?

     

    Thanks.

     

  • I just checked (I was sure I checked a few days ago, but I thought I'd check again). I did:

    hardCopyOptions(?hcOutputFile "./test.png" ?hcMakeExactCopy t)
    hardCopy()

    and I got this picture.

    Andrew.
