问题 I want to draw a rectangle with two strings in it. I want the first string to be 15pt size (its a number), second to be 10pt size (the label).

问题 So i want to draw on my image text lets say in this example "Trevor, 24" But I want to use the font Helvetica for Trevor, and for 24 i want to use the font Arial. But I want it to be on the same line and look like it's one. Is it possible or how would i go about making it so that even if i change the name and age, that i can print it out like this?
