How can i use a bitmap text (no anti-alias at all), i can't find that option , the same option that exists in the classic text field.
You should embed you own font with such properties.

I have font build by group of images to save writing shape, so this font is unicode and each unicode character presents a single word, until now every thing working fine with font coloring in the application.
after we update the font to contain static colors (inside the font ttf) the issue appear that I cannot change the uncolored parts of the glyph.
please see the attached image that contain four characters the first two was colored correctly (blue) but the others were not.
is there any suggestion to replace the black color only in the character with white color to be used in the Dark mode ?
I want to display some Hebrew text using Text and TextPath. In plain HTML5 it seems the best way is to set the dir attribute on the canvas to rtl (HTML5 Canvas fillText with Right-to-Left string). How do I do that in Konva?
const canvas = layer.getCanvas()._canvas;
canvas.setAttribute('dir', 'rtl');

I have an emoji, and I want it to be white, but when I run the program it appears red. How do I change it to white?
rating.text = "\(♥♥♥♥♥)"
rating.textColor = UIColorRGB("ffffff")
The following answer explains why you can't change the color of Emoji characters. The glyphs are essentially images.
If you want to be able to use a heart symbol that you can color, try using one of the non-Emoji heart characters like ♥︎.
Or ensure the label's font isn't using the Apple Color Emoji font.
I needed to do this for a project and found a couple of ways to go about it. Each has its limitations, but still, usefull tricks to know.
First, you could append the unicode text presentation selector after the emoji to get it to render as text, then use your font color.
Limitations:
Text representation of that emoji might not be available and you get unknown character representation instead.
The detail of the text representation is often less
Alternatively, you can use CSS filters on the emoji itself to change its hue (plus saturation, contrast, grayscale, etc)
Limitations:
Requires access to the page's css (Works fine for your own webpage, but you couldn't, for instance, use this within an instagram post)
The emoji graphic is application-dependent, so the outcome
could be unpredictable. For instance, the folder icon on firefox is
(presently) an ugly blue color. I filter it to a yellow tint, but on
other browsers (which render it yellow to start with) the code below will cause the very problem I was trying to fix!
Anyway, here are some examples with both css and html variations of the approaches:
.folderitem_normal:before {
content:'\1f4c2';
margin-right:4px;
}
.folderitem_presentation_selector:before {
color: magenta;
content:'\1f4c2\FE0E';
margin-right:4px;
}
.folderitem_css_filter:before {
content:'\1f4c2';
filter: hue-rotate(180deg) brightness(1.5);
margin-right:4px;
}
<div class="folderitem_normal">Normal appearance of emoji for comparison (HTML 📂)</div>
<div class="folderitem_presentation_selector">Presentation selector. Notice how it has been colored like normal text. (HTML 📂︎)</div>
<div class="folderitem_css_filter">Css filter looks nice, but results are application-dependent. (HTML = N/A)</div>
If you include Unicode characters in an NSString, a lot of them will take on the color set for that text - they're just regular glyphs for that font so they're displayed like any other character. But there are some Unicode characters that are colored, for example GLOBE WITH MERIDIANS which is a blue gradient with shadows. But I have seen this same glyph elsewhere that's a simple black outline without a shadow, for example in the iOS keyboard. I would like to use that glyph, but without the adornments, and without having to create and use an image. I wondered if a different font would render it in a different format, and while iOSFonts.com does show different styles (bolder, italics), they're all blue. Is it possible to get the simple plain version?
Surely it is possible, because that appears to be exactly what Apple has implemented with a Tip. Notice the globe is the exact same color as the text and it's included in the string along with all the other characters. Surely that's not a UIImage?
Character in different fonts:
EDIT: The solution provided in the linked question doesn't work for this character, as the variant character appears to be the exact same as the original - blue with shadows.
Unfortunately, iOS doesn't have a monochrome globe symbol you can use; the only built-in font that includes U+1F310 GLOBE WITH MERIDIANS is Apple Color Emoji.
If you really want a font that renders this character as a simple black outline, you could package a copy of Symbola (downloadable here) into your app.
Alternatively, you could make a bitmap image with the icon you want and use NSTextAttachment to put it into an attributed string. Apple is likely doing something along these lines, as many of their Tips include symbols that are definitely not Unicode characters:
Is it possible to change the font size of the code in in GVedit Editor?
I do not mean the font of text in created graphs, but the font size of the source code.
Copy the text from webpage or word to GVEdit, the format will not change.
But I haven't find where to config it.
