The baseline is an imaginary line that is used to ‘guide’ glyphs when rendering text. It can be horizontal (e.g., Latin, Cyrillic, Arabic) or vertical (e.g., Chinese, Japanese, Mongolian). Moreover, to render text, a virtual point, located on the baseline, called the pen position or origin, is used to locate glyphs. Each layout … See more A various number of face metrics are defined for all glyphs in a given font. 1. Ascent The distance from the baseline to the highest or upper grid coordinate used to place an outline point. It is a positive value, due to the … See more Because hinting aligns the glyph's control points to the pixel grid, this process slightly modifies the dimensions of character images in ways that … See more Each glyph has also distances called bearings and advances. The actual values depend on the layout, as the same glyph can be used to render text either horizontally or vertically: 1. Left side bearing The … See more As seen before, the ‘origin’ of a given glyph corresponds to the position of the pen on the baseline. It is not necessarily located on one of the glyph's bounding box corners, unlike many typical bitmapped font formats. In some … See more WebFortunately, FreeType 2 is flexible enough to support any kind of glyph format through a simple API. The glyph image is always stored in a special object called a glyph slot. As its name suggests, a glyph slot is a container that is able to hold one glyph image at a time, be it a bitmap, an outline, or something else.

Text Rendering using FreeType library not working correctly

WebPerforming 2D transformations on glyph outlines is very easy with FreeType. However, when using translation on hinted outlines, one should always take care of exclusively … WebNext you have to render the text itself on the same data you've blitted the outline. Use the code above, but remove the FT_Glyph_StrokeBorder (&glyph, stroker, false, true); line. This way you will have the text on top of an outline. To achieve this "Cartoon" text effect you will have to do 4 passes: 3 outlines + 1 text. WebAnother issue with FreeType font bitmaps is that the glyph textures are stored with a fixed font size, so a significant amount of scaling may introduce jagged edges. Furthermore, rotations applied to the glyphs will cause them to appear blurry. This can be mitigated by, instead of storing the actual rasterized pixel colors, storing the distance ... tots the not so spooky spider
