MagickWriteImage, when working with JPEG, calls open/close on file twice. E.G.: ... stat("test.jpeg", 0x14e0020) = -1 ENOENT (No such file or directory) open("test.jpeg", O_RDWR|O_CREAT|O_TRUNC, 0666) = 3 fstat(3, {st_mode=S_IFREG|0644, st_size=0, ...}) = 0 fstat(3, {st_mode=S_IF...

Hello.
Some time ago i wrote pure-c imagemagick bindings for lua: https://github.com/isage/lua-imagick
It's doesn't have full wand-api support, and new methods are added based on requests (or when i need them).
But even so it's pretty feature-complete.

How can i get it to be listed on website?

Digging deeper: it looks like "caption:" gets info about colors, etc. from Image -> ImageInfo, but wand methods operate on DrawingWand, which in case of Annotate you just pass along, but in case of "caption:" i don't really know what to do

Yep, that's the one i've checked.

6.9.2.7
I'm not seeing anything related in the changelog, though

Yep, that's the first thing i've tried

On the command line it's done via -fill, according to docs. Yet, none of *Fill* methods seems to work.
I've tried setting stroke color too, but to no avail

Sorry for bumping old thread, but i have same problem. Example: #include <stdio.h> #include <string.h> #include <wand/magick_wand.h> int main(void) { MagickWandGenesis(); MagickWand* m_wand = NewMagickWand(); MagickSetSize(m_wand, 100, 100); MagickSetPointsize(m_wand, 31); if (MagickReadImage(m_wand...

Sorry for bumping old thread, but why is opacity actually set by color and not by PixelSetAlpha/PixelSetOpacity?

Nevermind. I'm stupid. Forgot to typecast values from lua ffi. Case closed

Erm. Okay. Calling MagickExtentImage from pure c with negative offsets works. Calling it from lua (and i've checked by adding printf with passed parameters inside MagickExtentImage) with same offsets doesn't. Not sure what happens here.
Anyway, sorry, as it seems i was wrong.

2) Duh. Let's say i have 50x50 image. If i do MagickExtentImage(wand, 200,200, 10,10) image will be shifted 10px left and up (to the outside of canvas) - that works fine. If i do MagickExtentImage(wand, 200,200, -1,-1) - i'll get blank image (while, obviously, it should just shift 1px to the right a...

1) MagickExtentImage ignores gravity
2) passing negative offsets (which i get from 'GravityAdjustGeometry') to MagickExtentImage results in blank image

4 years later, and it's still the issue in recent pkgs on ubuntu/fedora. Moreover, Magick++ supports gravity for extent, and, while doing the same (eg. calling ExtentImage) as MagickExtentImage produces proper image with same arguments. Sadly, i'm writing lua binding, so doing wrapper for a wrapper ...
