[ft] Performance problem in getting string width
Hi All, I have modified ftstring.c according to my environment . For drawing a string freetype has to do kerning and it has create a new bitmap for each character. But for width calculation of a string also it is doing the same computations. For getting width of the string I dont want any bitmap, I just want left, top, and width for each character. Is there any code snippet which can help me in improving the performance of calculating the width for a string.

[ft] Problem with text color
Hi All, With gray-scale font I am getting a buffer . Each byte in the buffer has 0 to 255 levels of gray values. I am doing raster operation using this buffer to my device screen to draw the font. But the problem is how can I draw different colors using this gray values. I mean rgb( 0, 0, 0 ) gives black and rgb(255, 255, 255) gives white and rgb( 150, 150 ,150) gives some light black or gray color. These 0, 255, 150 are gray values of the buffer. Using the above logic I am able to draw black text, I am not able to draw other text colors. Is there any algorithm to get native color value using gray values. I mean if I want to draw with pink color rgb_new( 0, 0, 0 ) should give pink color, rgb_new( 150, 50,150) Should give light pink color and rgb_new( 255, 255, 255) should give very light pink color. Then I will get a smooth border for the text with pink color. Please help me how to draw with different colors.
