I’m generating a shader code and displaying it.
But sometimes it’s not readable, so I would like to put black as a background color for shader code.
code for displaying shader code
ofDrawRectangle(0,0, ofGetWidth(), ofGetHeight());
codeFont.drawString(fsCode, ofGetWidth()*.1, ofGetHeight()*.1);
Could anyone tell me a good way to do that?
Thank you in advance,
Hi you can use
ofDrawBitmapStringHighlight(string , float x, float y) which will use the default bitmap string (there is no need to load the font or anything) and it will put a black background and white letters. If you pass a 4th and 5th arguments you can specify its colors.
If you want to use another font you can call
ofTrueTypeFont::getStringBoundingBox(...) which will return the rectangle that contains the text, which then you can draw.
Thank you for your answer.
