In my practice, I have not used the frame when overlaying layouts.or just kept one without the background removed, and layered more layouts on top of it without duplicate frames. My only beef is that the black text in the “frame” and title of the layout (e.g., “3D Layout”) has edges highlighted with white pixels that makes the frame difficult to read. The surfaces and rays all look fine in the layout afterward. *** Instead, use Color > Set Transparent Color.Ĭursor changes to a different type of arrow pointing diagonally to the left and down point to a pixel in the white area WITHIN the selected picture, and click to make all pixels of the white background transparent. Under Picture Format tab, do NOT choose the “Remove Background” tool at the far left of the menu, because it requires you to draw an area to keep or to remove (OK for cutting out a patch of an image, but not for areas between rays!!).Īlso, do NOT try to use Transparency > Picture Transparency Options… because that applies transparency to every pixel in the entire image. I found the PPT technique to make the white areas in a OpticStudio sequential 3D Layout transparent, and have tested it in the most recent Microsoft Office 2021 for Mac (perpetual license).įirst select the layout picture in the PPT. Who knows, maybe you could “launder” an image through one of those? And their non-free SoftMaker Office is inexpensive, too. Their equivalent applications are PlanMaker (spreadsheet), Presentations (like PPT), and TextMaker (word processor). I actually don’t have Microsoft Office on my Windows 10 “Zemax computer.” I use SoftMaker FreeOffice (from German company SoftMaker which is quite full-featured.maybe you can try that if you’re a Windows guy. Not sure whether it (or Windows equivalents that might be available) can actually create transparent backgrounds, though. I have the latest perpetual license version 2021 on my Mac and can look for that there.Īnother thing I have done is used a free photo editor on the Mac (Seashore) to layer images. Meanwhile, thank you for mentioning the built-in PowerPoint feature. If I find something to work with Sheets (which I never use), I’ll let you know. Gah! Sorry I missed some of your essential points (like you are being asked to paste pictures not into Google Slides (presentation software like PowerPoint) but instead into Sheets (spreadsheet software like Excel!). If you find good alternatives, RickSPI58 or Mark, please add them to this thread anytime! I don’t know who these “Team Browserling” guys are, but I appreciate their making these tools available. Look at the drop-down menu of these other conversion pages at the far upper-right of either of these pages. And I have had good luck using PNGs in PPT (as opposed to JPEGs). to a JPEG using the “onlinejpgtools” page, the output turned out to be in PNG format, anyway. There are also versions of these tools for MANY other file formats, but if I recall correctly, trying to do this e.g. But once you have your settings tweaked (thresholds for background color etc.), it doesn’t take too long to do this to multiple files that you can then insert/overlay into PPT. One must do this one file at a time, and take care of file naming for the output files (which are all initially saved with the same file name). I think I have found other online file editing tools in the past that can do this, but most recently this is my favorite for its convenience in uploading files and variable configurations to optimize the appearance of the output file. On this page, the tool to “Make a PNG Transparent” is the upper-left box/button, which takes you here: I’ve been using tools at this web site for the occasional file: I also have often needed to make a background transparent. I am too cheap to actually buy a utility if I can find a free one online (that doesn’t scare me too much by looking like malware).
