Bugs in graphic functions

[wangchong01]

Hello,
I found a bug when I was using the BILT_P function.
When you are using the function like this:

Code:

DIMGROB_P(G1,320,1000);
BLIT_P(G0,0,0,320,240,G1,-100000,0,-100000+320,241);
FREEZE;

Your screen will be in a mess.I think The BLIT_P function will copy the memory in front of the GROB if you copying the GROB with zooming and x(or y) below zero.
When you are using DIMGROB_P in this way:

Code:

DIMGROB_P(G1,320,1000,#FF000000h);

The content of the GROB will also display part of the calculator's memory.

I have made some programs to read the memory by the bug. The appicon,icon and lt attached are png files. The program readmem and mem2file must be used after the disp2 or disp runs.
Here is part of my calculator's memory:

I found another bug of the drawing function. The alpha in different functions or different usage gives different effects,for example:

Code:


RECT_P(0,0,100,100,#400000FFh);
FREEZE;

Code:


RECT_P(0,0,100,100,{#FFh,#40h});

Code:


DIMGROB_P(G1,100,100,#FFh);
BLIT_P(G1,0,0,100,100,#0h,#40h); //the usage of alpha is not said in the help, this is another bug.
FREEZE;

Code:


FILLPOLY_P([(0,0),(0,100),(100,100),(100,0)],#FFh,#40h);

Code:


TRIANGLE_P(0,0,100,100,0,100,#FFh,#FFh,#FFh,#40h);

These codes gets completely different results, I think the alpha of FILLPOLY is correct while the RECT is very strange. (you can see it in detail at http://www.hpmuseum.org/forum/thread-6994.html)
