This is all you need to know for this tutorial. So, before you copy and paste your icons into Glyphs, scale them up to approximately 700 points in the originating application. And since by default, the UPM is set to 1000 units, the average cap height will be 700 units. The average cap height is 70 percent of the UPM (units per em) size. And, usually, you will want your icons to be approximately the size of a capital letter. Keep in mind that one point in Illustrator etc., will be one unit in Glyphs. And since scaling in Glyphs can lead to rounding errors, it is best to scale your artwork to the right size before you bring it into the font. From most vector apps, you can simply copy and paste into Glyphs. Glyphs provides great drawing tools, but chances are you already have vector icons. If you want to know more about glyph names, read through the Getting your glyph names right tutorial. So, homeIcon and loginIcon are okay, but names like home button and MäxIcon are not okay. Spaces are not allowed, and the name must not start with a figure. Only use upper- and lowercase ASCII letters, i.e., A-Z and a-z, perhaps figures (0-9) at the end of the name. Or simply add Icon to the end of the glyph name and you will avoid all trouble. Glyphs has a built-in list of glyph names it recognizes, and you can see it in Window > Glyph Info if you like. If it changes again to something outside the PUA, chances are you picked a name that is reserved for another glyph. Keep an eye on that Unicode value after changing the glyph name. When Glyphs asks you whether you know what you are doing, say Remove: So, the first thing we do in the Font window, is select all glyphs and click on the Minus button at the bottom of the window. Why not an icon? Because it can confuse search engines, the search function of your website, or the person trying to make sense of what is displayed on the screen if, for some reason, our icon webfont cannot be loaded and is substituted with a fallback font. So, for instance, into U+0041 LATIN CAPITAL LETTER A, you should only ever put something that at least vaguely resembles an A. Into a Unicode-assigned glyph, you should only put pictures that match the meaning of the Unicode value. If you want to know more about Unicode, glyphs, and characters, read the Unicode tutorial. Sometimes, glyphs do not have Unicode values, but in our icon font, each glyph will have one. The character-glyph relationship is established through the Unicode value assigned to a glyph. In short, characters are what you type, glyphs are what you see.
The slots inside a font are called glyphs (hence the name of our favorite font editor), and those glyphs usually correspond to characters. When you are done, close the Font Info window (or tab) to return to the Font window, and perhaps save your font again. Rgba.save(“transparent_image.The other stuff is not important to us. Store the newData into RGBA value and save the image as a png format(transparent image can’t be stored into jpg or jpeg format). And we will store the values in a new list called newData. Now we will loop through the data (RGBA values) and whenever we find a black pixel we will replace it with a transparent RGBA value which is ((255, 255, 255, 0), and the other colors will be unchanged. Here in this image, the background color is black. To make transparent the background firstly we have to find the RGBA values of the background or any color we want to make transparent. Python program to convert a list to stringĭata will be an Imaging Core object containing thousands of tuples of RGBA values.
