Can I save image created in PowerPoint as a printable vector?
I was asked to create a logo to be printed on a large number of t-shirts for an event. I designed the logo in PowerPoint using text, shapes and a .png image. The people from the printing company said that they need it in vector format (corel, adobe illustrator or editable pdf). I exported the logo as a .emf / .pdf file, but they say the image is still bitmap and they need it in vector file. Is there a way to export the image from PowerPoint so that they can print it?
While EMF and PDF can both be vector formats, you say that your logo contains a PNG image. PNG is a raster image format, so when you export to PDF or EMF, you'll have a vector image with an embedded PNG. This is probably the issue your printer is having.
You cannot simply convert a raster graphic like a PNG file to a vector graphic by saving it as a vector format. You will need to either 1.) re-create the PNG aspects as a vector or 2.) use an application like Adobe Illustrator to trace it.
If you are looking for a free program for vector graphics, I'd recommend Inkscape. Inkscape does have limited tracing abilities, although your mileage will vary depending on your image.
[I feel that I have a moral duty to tell you that PowerPoint is not for drawing things. PowerPoint is for making dreadfully boring slideshows with cheesy star-swipe transitions and clip art circa 1998. Use the appropriate tool for a job. Use Inkscape, Illustrator, or even LibreOffice Draw to make your logo; use PowerPoint for the Annual Q4 Sales Working Group Planning Meeting presentation.]
