QUESTION
I'm making a text renderer that uses FreeType 2 and legacy OpenGL. Problem is, FreeType 2's coordinate system has (0, 0) in the top left corner while OpenGL's coordinate system is Cartesian. This means I have to flip the bitmap. I expected glScalef to work with glBitmap but it has no effect. Can anyone tell me if it's possible to flip a bitmap vertically with glScalef, or if it is not possible, point me to some other source that can flip a bitmap upside down (Preferably efficiently as possible)?
...ANSWER
Answered 2020-Sep-08 at 22:08The function you are looking for is glPixelZoom
.
Pixel zoom factors are not limited to positive values. Negative zoom factors reflect the resulting image about the current raster position.
It definitely will have the desired effect on glDrawPixels
. There's a note in glBitmap
saying that it acts like glDrawPixels
but I cannot find any explicit statement on whether glPixelZoom
applies to glBitmap
or not, so YMMV.
QUESTION
This is my python program to solve the 8-queens problem. Everything is working except the final step of printing the solved board. I use recursion/backtracking to fill the board with queens until a solution is found. The board object that holds the solution is self
, which is a reference to b1
, so I assume that b1
, the original board I initialized, would be updated to contain the final solved board, and would print the solution using printBoard
. However, b1
is not being updated and is holding a failed board when I print it for some unknown reason.
edit: added placeQueen
in solve
ANSWER
Answered 2019-Nov-26 at 21:04I believe your problem is related to redefining self in the solve method, andi'm not even sure why you're doing that.
See this question for more details: Is it safe to replace a self object by another object of the same type in a method?
Reassigning self like you're doing is not reassigning the "b1" reference. So when you reference b1 again and do printBoard, you're referencing a different object than what "self.printBoard()" will be referencing by the time solve is done.
I would step back and ask yourself why you're replacing self to begin with, and what this gains you. You likely don't need too and shouldn't be doing it either.
QUESTION
I am not a very efficient vba coder, but I can brute force my way through something. I am trying to optimize this code to have it run more quickly. I would imagine it should be possible to combine the loops somehow, but I am not exactly sure where to start since the Sheets are within the formulas. Any assistance would be greatly appreciated.
...ANSWER
Answered 2019-May-06 at 22:26You want to avoid repeating yourself. Whenever you have duplicate code you need to break it out in to it's own procedure and then call it using the variable that makes it unique. In your case the only unique part is the sheet you are operating on. So I made this example procedure that you can pass sheet objects to:
QUESTION
I have 1 column with 200 numbers. The number starts from zero, goes to a highest point(X), then reduces to minus value to the lowest(Y) and then increases. Finally it ends in zero. 0 1 2.... 10 3 2 -1 ....-10 -9 -8... 0
I got the maximum value using
...ANSWER
Answered 2018-Feb-18 at 12:37This function returns the address of the cell that contains the maximum value in the specified range (or an empty string if there's a problem, like if the range doesn't contain values):
