Thread: Gd graphics library help

Did you do this first; copied from your last thread. Drawing an image in C

Code:

gdImageSetThickness( gdImage, 2 );

Thanks,

That disagrees with your prior statement. You said it happens on the first card.
There is no card before the first card in your screen shoots.

EDIT: Do you understand that if the thickness is NOT set it could be very large?
That is why I suggested adding this line!

gdImageSetThickness( gdImage, 2 );

First comment out any drawing for hearts, clubs and spades. Does it draw a blank card correctly?

Add the drawing back bit by bit, making sure that each individual shape is drawn correctly (ie draw only 1 rect by commenting out the other rect and ellipses, does the rect appear in the correct place? If so comment it out and comment in the next rect.)

>>gdImageFilledRectangle( gdImage, 105+(WordLineUpX*140), 130+(WordLineUpY*195), 95+(WordLineUpX*140), 170+(WordLineUpY*195), black );

This is drawn in reverse ie x left = 105 and x right = 95. The docs say it draws top left to bottom right. Is that confusing the drawing? (don't think this is the error or it would always draw 'spades' incorrectly)

As stahta01 pointed out it may be the width setting. Your examples have the 2nd card as a Diamond.

Do you get the same error repeated for more than just the first card (if the 2nd card is not a Diamond)? (ie all drawing fails until the the fist diamond is draw, in which the drawing code sets the thinckness for all future drawing, so then all drawing succeeds.)

BTW Royal Flush beats 4 of a kind and 5 of a kind (ie 5 3s) is usually impossible in poker (least from what I remember from my time as a croupier, before I started spotting trains...).
