Monochrome uses only black and white, so you can insert the image into a document and print it on a normal printer. You should now see a "Copy Graphs WMF" menu in between Copy Graphs BMP and Copy Graphs EMF.Ī cascading menu allows you to choose between color or monochrome:Ĭolor uses the current color scheme (the default gray scheme if in monochrome mode). Add the line " copywmf=on" to the section of your graphmat.ini file.Use of the WMF format is not recommended, though, as there are serious defects in its text handling capabilities that make it impossible to position annotations, legends, or other graph labels reliably. Support for standard Windows Metafiles has been disabled by default for the 32-bit version, but can be turned back on if you require the ability to export graphs to older applications that do not handle the enhanced metafile format properly. If you intend to print the image, you should copy the graphs as a metafile if possible. Note: for the best possible image quality, Graphmatica re-renders the graphs at the maximum possible resolution for your screen when producing metafile output. Word 97) to see the advantages over regular metafiles otherwise Windows will convert your EMF to a WMF which looks worse than if you just copied a WMF directly (Windows 95 loses the size information attached to the image and Windows NT ignores pen-width settings when doing this conversion). Note that you need to paste the picture into another 32-bit program that uses enhanced metafiles (e.g. Unlike old Windows metafiles, enhanced metafiles are designed to handle text properly so you will see the titles and legends when you use Copy Graphs EMF. The copied image will always be the same resolution as the grid shown on the screen, so if you want a large picture, maximize the window, or for a smaller size, make the window smaller.Ĭopy Graphs EMF prepares an enhanced metafile of the graphing screen. Hint: for the best possible quality of raster images, let Graphmatica size the bitmap for you instead of scaling it with the paint program or word processor. PDF will provide higher print quality images using less memory. Use the Paste Special command in the target application to choose which format is pasted. On Mac OS X, the Copy Graphs menu item copies both vector (PDF) and raster (TIFF) images to the pasteboard simltaneously. You can then paste it into virtually any paint program and do whatever you like with the image. Many websites have strict rules that limit the size and type of image format you’re allowed to upload. On Mac, open the image in Preview and go to File > Export to save the image as a JPG. Graphmatica offers a number of options to copy a graphic of the grid and your graphs to another application to incorporate in another document to print or publish.Ĭopy Graphs BMP copies the current graphing screen into a bitmap and places it into the clipboard. To convert an image to JPG on Windows, open the image in Paint or IrfanView and navigate to File > Save As to save the image as a JPG. (Note that this is, more or less, a copy of the entry I made on. * Maxima can't load/batch files which end with a comment! */ Now, all you have to do is click on Convert. Upload your video, document or video from your hard drive, a cloud storage or even by using the link to an image from the internet. This tool allows you to convert many files to JPEG. The resulting plot is not quite as nice as the plot above (the lines around the head don’t have that nice ‘straight line’ look), but seems more ‘legitimate’ to me (in that any reasonable solver should plot a similar shape). Try the following in Maxima (actually wxmaxima) which is free. Furthermore, a nice solution would be ‘robust’ in that small variations (such as those arising from, say, roundoff) would perturb the solution slightly (as opposed to eliminating large chunks). It seems a little ‘sneaky’ to rely on the solver to ignore complex values and also to conveniently ignore undefined values.Ī nicer solution would be one that is unequivocally defined everywhere (in the real, as opposed to complex, world). Indeed, since we’re dealing with real numbers, this value is really only defined when $x>0$. As Willie Wong observed, including an expression of the form $\displaystyle \frac$ is undefined when $x=0$.
