Can Magick colour this specific (light blue) area?

In this bmp: https://drive.google.com/open?id=1bcDd075j9H8VPHuyVrDwfy8OrE4_2kvQ Can Magick colour this specific (light blue) area? I can feed the bmp the magenta line(segment) or just the end point coordinates, here (64, 50) and (119, 134). When feeding coordinates Magick would have to compute the d...

Re: Behaviour of -define bmp:subtype=RGB565

It never occured to me to drag the bmp to Firefox in which it looks OK.
Now first I need to see how much I need this, thanks.

What I see is in the zip. rslt is the top image because of the specific top right corner.
I've done this on an XP machine as well, it's the same.

Which version introduced bmp:subtype=RGB565 ?

Behaviour of -define bmp:subtype=RGB565

Apologies if this is just pebkac or if it's known already but I could not find info specific to this possible bug. Using ImageMagick-7.0.8-60-portable-Q16-x86.zip on win7 I find the command convert tst.bmp -define bmp:subtype=RGB565 rslt.bmp gives a shift of 6 pixels to the left in rslt.bmp. The six...

Re: Paste an image without it's transparency.

If I turn alpha channel off in the foregroundimage I see a big white blob where the other (background) image should be. Maybe this is a better way to say it: foregroundimage transparent area + backgroundimage non-transparent area = non-transparent backgroundimage and foregroundimage non-transparent ...

Re: Convert BMPs for use in SFML.

Files like BMP, JPG, PNG, TGA, PSD, and DDS. But if you mean a specific type of PNG, I haven't been able to find that. I do have an answer however; using -Q16 i do: convert car.bmp car.MASK.bmp -compose CopyOpacity -composite textlogo.png I leave out PNG8:, it'll be a PNG32: then. This seems to be w...

Re: Convert BMPs for use in SFML.

Thanks, this copies the colors OK but the gray areas (hex 808080) in the mask are now fully transparent too. And I would like those to be 50%. PNG8: always has only one bit for transparency I understand now. If so, that's not what I need. I started experimenting with things like '-type Palette' and ...

Convert BMPs for use in SFML.

Hi, I'm trying to convert some old DirectX 6 files I made to PNGs to be used in SFML. I have a car.bmp and a car.MASK.bmp where the MASK file has only the colors white, black and gray. Those indicate no transparency, full transparency and semi-transparency respectively. So I'd like to see the colors...
