Huge memory increase when using FreeType Font

| Why is there such a huge increase in memory when using FreeType Font? From about 10000K ~ 15000K to 25000K, is there any alternative to FreeTypeFont or way of lowering the memory usage? Last edited 2010 |

| When did 10 megabytes become a "huge increase in memory"? I don't know what "FreeType Font" is, but if you're loading a bitmap font, a 2048x1024 texture, with mipmaps, would be in the ballpark of that amount of memory. So are you loading a font that would be too big to fit all characters on a 1024x1024 texture? Last edited 2010 |

| Well seeing as I'm working on a lightweight media player, 10mb of memory is quite the increase (almost double the amount of memory) ;) And I'm on about brl.FreeTypeFont which is the default Module for drawing fonts using Max2D's DrawText function. LoadImageFont(), SetImageFont() etc. all comes from brl.FreeTypeFont. |

| You didn't answer my question. LoadImageFont sounds as though the answer to "if you're loading a bitmap font" is yes, but are you requesting a font size that would struggle to fit all the glyphs on a 1024x1024 texture? |

| Use the BLide font machine module. It will also provide correct text sizing. The built-in BMX text functions don't display fonts correctly. |

| Josh, perhaps it would be helpful to the Blitz community if you were to suggest a fix for the BlitzMax implementation, from a quick browse this morning it looks like brl.freetype should be using the FT_Set_Char_Size command in place of the FT_Set_Pixel_Sizes function? |

| @JoshK BLide font machine doesn't support .ttf files which is want I need to load. :/ |

| Use FT_Set_Char_Size(face, 0, size * 64, 0, 96), where size is the font size. I don't use that pixel command. The offset for each character is given by these: face->glyph->metrics.horiBearingX/64; face->glyph->metrics.horiBearingY/64; The spacing for a character is this: face->glyph->metrics.horiAdvance/64.0; The width and height are given by the bitmap.width and bitmap.rows. So for each character: Draw a rect at x + offsetx, y+offsety that is width x height. Then add the spacing to x and draw the next character. Last edited 2010 |
