<div dir="ltr">I am not entirely sure what 1 is. However, for 2, try changing the "Scalar Opacity Unit Distance" from the "Properties" panel. ParaView will set it to a value based on the data spacing after the first "Apply". If you change the spacing after that, you can use the "Reset using current data values" button next the option on the "Properties" panel to recompute using the current data values.<div><br></div><div>Utkarsh<br><br><div class="gmail_quote"><div dir="ltr">On Tue, May 26, 2015 at 7:29 AM Thomas Oliveira <<a href="mailto:thomas.oliveira@gmail.com">thomas.oliveira@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="gmail_quote"><div dir="ltr"><div>Hi,<br><br></div><div>I have two problems that happen when setting the size of the voxels of a raw image.<br>Do you have any idea about it, please?<br><br>1) When I import a 3D raw image, if I set the data spacing, i.e., the size of each voxel, to 1,1,1, I can correctly visualize and rotate the image. However, if I set the voxel size to the values I need (5.549E-6,5.549E-6,5.549E-6), the image is rendered as if clipped when turned to certain angles (please see picture thisShouldBeCuboid.png attached).<br><br>2) Another problem for the same image is that, if the data spacing is set to 1,1,1, I get a certain contrast between grey and white (size1.png). If it it set to 0.1,0.1,0.1, the grey color becomes whiter (size01.png). Finally, when it is set to the correct small size, it is completely white.<br><br></div><div>Thank you for your help,<br><br></div><div>Thomas Oliveira<br></div><div><br><br></div></div>
