Hi, I use the following code:
BMAP* screenshot = bmap_createblack(245,110,24);
bmap_save(screenshot,"blackpic.bmp");
I expected to get a picture with width 245 and height 110, but I get a picture with width 256 and height 128? Any ideas why? The manual says: "bmap_createblack creates a black bmap with given dimensions that can later be filled with a color." Best regards, Pegamode.

Ive found the same thing.
I think the bmap_create/createblack may be forcing a "power of 8" size on us.
Possible bug?

Ancient Bump. Still no answer? I had fogotten about this.
Again, what if we want a BMAP in an odd size thats NEVER going to be used as a texture?

BMAP* name = "#(width)x(height)x(bits)"; BMAP* bBlack = "#200x100x32"; // define a 200x100 pixel bitmap of 32 bits per pixel I hope that is what you need  greetings KDuke PS: EvilSOB your a desecrator of corpses!

No good, thats a size thats fixed at compile time, I need one where the size is decided at run-time... PS: HEY!, it became MY corpse once Pagamode lost interest in it. Im no desecrator, Im a re-cycler...

var bmpSizeX = whatever;
var bmpSizeY = whatever;
var bmpColorDepth = whatever;
STRING* bmpCreateString;
bmpCreateString = "#";
str_cat(bmpCreateString, str_for_num(NULL, bmpSizeX);
str_cat(bmpCreateString, str_for_num(NULL, "x");
str_cat(bmpCreateString, str_for_num(NULL, bmpSizeY);
str_cat(bmpCreateString, str_for_num(NULL, "x");
str_cat(bmpCreateString, str_for_num(NULL, bmpColorDepth );
BMAP* bBlack = bmap_create("#200x100x32");
That should do even in runtime greetings KDuke

Hmmm, I hadnt thought of that way... Brilliant! Mind you, just saying BMAP* bBlack = bmap_createblack(216,325,32); would be SOOOOO MUCH easier... var SizeX = 216;
var SizeY = 325;
var CDepth = 32;
STRING* bmpCreateString = str_create("");
str_cat_num(bmpCreateString, "#%.0fx", SizeX);
str_cat_num(bmpCreateString, "%.0fx", SizeY);
str_cat_num(bmpCreateString, "%.0f", CDepth );
BMAP* bBlack = bmap_create(bmpCreateString);
diag_var("\n\nWidthxHeight = %.0f, ", bBlack.width);
diag_var("%.0f\n", bBlack.height);

It definitely would be easier if bmap_createblack would support this, I gotta agree. Though one could request that for the next update . greetings KDuke
