QUESTION

How is FreeType calculating advance?

Asked 2021-Feb-28 at 19:34

I am trying to figure out how the FreeType Library is calculating the FT_GlyphSlotRec_'s advance variable. According to the comment blocks above this structure, this variable would be the same as the horiAdvance variable further explained here, which is contained within the FT_Glyph_Metrics_ structure.

In any case, take the typical Arial narrow font as an example. It can be found in C:\Windows\Fonts\ARIALN.TTF. Uploading it to any of the web based TTF file editors (option 1, option 2), or using your own program that can interpret TTF files (fontforge, etc) you can see the Advance for the '!' character is clearly defined as 467.

I am running the following code and when I read FT_GlyphSlotRec_'s advance.x value, I get a value of 1472. Obviously this is not the same as 467. Am I misinterpreting what this represents? Or am I using the FreeType library incorrectly?

I am retyping the code I used to get 1472 from a computer without internet, so please forgive me for any mundane syntax errors.

As indicated on that Tutorial, Step 2 page you linked in your question, those metrics are usually reported for a 26.6 pixel format. You are modifying that by the way you're loading in the font. You can use the FT_LOAD_NO_SCALE to "[not] scale the loaded outline glyph but keep it in font units."

Your code generates a bitmap version of the glyph at the size you've requested at a default screen resolution of 72 dpi. The 1472 you're getting is the number of pixels * 64 used to draw the character in your bitmap. So, in this case, 1472 / 64 = 23 pixels, which would be the distance you would advance your draw cursor/pen point if you were drawing multiple characters into the same bitmap.

The 467 is in 1/2048th vector units. To make the conversion with a font_height of 100 pixels, it's: 467/2048 * 100 pixels, which is 22.8 pixels. Round to 23 pixels. Multiply by 64 to get 1472 1/64th pixels.

If you want to see it line up with the pixel value, set your font_height to 2048, then divide the resulting face->glyph->advance.x (29888) by 64, which will give 467.

The following script will give you the values you are looking for:

QUESTION

How to extract set unicodes from an iconfont and display them in WPF

Asked 2020-Dec-27 at 14:13

I want to create a generic icon picker application. You select an iconfont and the application renders all available icons and you can copy their unicode selecting an icon.

I found this post Get supported characters of a font - in C# and I thought that's exactly what I need and implemented it. I've put the found unicodes in an ObservableCollection and rendered the collection as an ItemsControl. This kinda works actually, but the displayed glyphs are no icons, rather than usual letters.

My guess is, that I messed up the conversion from the found characters to my unicode characters in the ObservableCollection?

You can't.

You're attempting to reduce a map with 6 elements into, evidently, a map with a single element in it (if this is an example, and the resulting map will ever contain anything but exactly 1 key of value "Manikanta" -> "VeryGood_Cool", you're going to need to update your example).

streams (I gather that is what you mean by 'in lambda expression') excel at operating on a single element in the stream (so, say, the notion "Saroja"->"Good"), or on how to turn the entire stream into a different collection (such as: Turn the whole thing into a list of keys).

You could write a custom collector; it would not be any shorter than this code is, and would be a lot harder to read. Hence I don't see the point of showing that.

Using .map() with useEffect and Api

I am trying to use the useEffect to grab some data from an API. I am succesful in grabbing the data but after I set my state and try to map through it I just get "Can't read map of undefined".

axios.get is an async function and you are trying to get the data outside of an async function which is no completed yet.

You could use useEffect with dependency array which is equal to componentDidUpdate to get the data.

Initialized the state with the same datatype that you expect, in this case we expect an array you initialized ith with empty array.

You can do something like below. Essentially, you use negative margins to meld all the borders together. On a parent border set a Padding="1" so that the negative margins along the edges can be seen.

The Border around your Button in your DataTemplate would look like this:

ANSWER

Answered 2019-Oct-08 at 11:09

When the CharacterMapControl is constructed, the dependency property value will be null, as the default value is not specified while defining the dependency property.

Little after constructing the control CharacterMapControl, the loaded event will be raised, at this point the dependency properties will have initialized values.

Modifing the constructor as below will help in understanding more.

QPaintEvent is a method that allows you to make an intelligent painting, that is, to paint where necessary, thus saving resources, for example it gives us the information of the rectangle that must be painted through event->rect(), with this we can calculate the items that have to be painted since others will be hidden and therefore it is not necessary to paint them:

I think you can get what you want using ImageMagick which is installed on most Linux distros and is available for macOS and Windows.

Basically, you need to tell ImageMagick, from the command line, to create an image containing the word "Test" and ask it to tell you the font metrics in its debug output as it does so:

So, here is an example from Anthony Thyssen's excellent "ImageMagick Usage Pages" here
