Although pages 3 and 4 will be created, I won't print them.
For my example, the original PDF page size was Letter, not A4, so the aspect ratio is slightly different. There are scaling options here, too - expermient as required. For A3, this is 2 A4 sheets wide, when in portrait. The red lines are where you'll be taping. Step 3: Set overlap positions (defaults to Bottom Right), and overlap depth (default 5mm) Step 2: Define the printer paper format and orientation (for me, A4, portrait) Step 1: Select source image (ie the GIF) - click the yellow folder iconįor some reason, GIF is now 72dpi and three feet wide, but this gets correctly scaled, in the end. Open the GIF file in PosteRazor and follow the five-step wizard: Note: To preserve the PDF import settings (dpi, anti-aliasing), leave GIMP open after export - it may revert to defaults if closed completely and reopened.Ĭlose the image in GIMP (File | Close, or CTRL+W)ĭ. Export from GIMP as GIF (File | Export, or CTRL+SHIFT+E)
If necessary, trim the image to remove superfluous white space surrounding the imageĬ. At 1200dpi, GIMP uses a lot of memory for the images. To avoid crashes, import a single page at a time. To avoid nasty print artefacts, disable Anti-aliasing To preserve resolution (esp when printed on A3), a high resolution (1200dpi) should be chosen, twice the printer's physical limit is probably a waste of time, though.
Import single page from PDF into GIMP (drag PDF file onto GIMP from Windows Explorer) Tested on Win7 圆4, GIMP 2.8.14, PosteRazor 1.5.2 (current versions as of ).Ī. This method should work (no guarantee) to posterise any sheet from any PDF, and provides pretty readable text, even if the original text was tiny.īoth GIMP and PosteRazor are available for Windows, OSX, and Linux. PDF -> GIMP -> PosteRazor -> Print up and tape. The following method gets around this by using GIMP as an intermediate step - extracting a single page from a multiple-page PDF, converting any vectors into bitmaps, exporting as a high-resolution, single-page file which can be posterised by PosteRazor. Unfortunately Inkscape has a bug where exporting to PNG (which PosteRazor can read) is *always* anti-aliased, and pretty nasty when printed. Inkscape (also free) is great for vector graphics, and it will happily import a page from the file, convert the vectors to SVG. The file dates from 2001, and the (unknown) schematic program may actually have been designed to plot, not print. Unfortunately, PDF (which is more of a container, than an image format) is not included, and many schematics are exported/published in this format.Īlso, I've just come across an odd situation, where a multi-page schematic in PDF actually comprised vector data - much like plotter data - which presumably was directly embedded when the PDF was created. Input file formats are documented at PosteRazor - Make your own poster!, but they're basically limited to raster image formats.
Sounds great, and I'm not aware of any other free software that does this. These can be taped to form a poster (hence the name) up to 5m(!) wide. PosteRazor is designed to split image files into individual pages in a single PDF file, on whatever page size your printer can handle. Open source image manipulation program - sort of free Photoshop, plenty of info around.Ībout PosteRazor - PosteRazor - Make your own poster! To illustrate point 3: my printer will print multiple pages per sheet ("2 in 1" - ie reduce), or print an A4 page on (n x n) sheets (A2 - four times the area), but there's no option to double the size to A3. Following (free/OSS) programs are available: A3 size wanted (ie two sheets A4, with some overlap for taping together)ĥ.
Printer drivers can't solve the problemĤ.
You have a schematic in PDF format, but it's hard to read when printed on A4ģ.
