<br>Hi Pat,<br><br>
Thanks for your suggestion - but didn't help, PV-3.8 still crashed.<br><br>I am able to save the screen shot using other formats (jpg, bmp etc).<br><br>I looked into it a little bit further and I think this is where its seg faulting<br>
(I am on 3.8 release branch, not the latest CVS)<br><br>in vtkPNGWriter.cxx<br><br>line 278 - the following for loop<br><br> for (ui = 0; ui < height; ui++)<br> {<br> row_pointers[height - ui - 1] = (png_byte *)outPtr;<br>
outPtr = (unsigned char *)outPtr + rowInc;<br> }<br><br>However, if I put a print statement inside the for loop(Hello world for example), PV doesn't crash. This may be due to a memory leak some where else.<br>
<br>Can some one please comment on what sort of modifications I should make to the above code?<br><br>I think this may be a nasty bug to recreate - has any one else encountered this problem? <br><br>This is what I tried to do<br>
<br>start PV<br>Load some data<br>File->SaveScreenShot-><br>Now choose the .PNG format and my PV-3.8 crashes<br><br>Regards,<div><div></div><div><div><div></div><div><br><br><div class="gmail_quote">On 12 August 2010 19:26, pat marion <span dir="ltr"><<a href="mailto:pat.marion@kitware.com" target="_blank">pat.marion@kitware.com</a>></span> wrote:<br>

On some systems, this option will cause a crash when enabled.<br>

Hi<br><br>I have a .pvti file which I can visualize in Paraview-3.8.0.<br><br>I would like to save a slice from my data set and able to display the results correctly.<br>However, when I select SaveScreen option with PNG format, it seg faults.<br>
<br>I am able to get this to work correctly on 3.6.2 without seg faulting.<br><br>I am on SuSe-10.2.<br><br>Do I need to turn on the USE_SYSTEM_PNG flag in CMake and re-compile?<br>I haven't done this for 3.6.2 and works OK.<br>
<br>Has any one else come across this problem before? <br><br>Any pointers would be greatly appreciated.<br><br>Regards,<br><font color="#888888"><br>Rakesh<br>
