Legacy ImageMagick Discussions Archive

Using c++ API - namespace Magick, version looks like 6.8.5, released on the 24-4-2013. Package name ImageMagick.

Just a thought for anyone who might know - is it possible to do an iter_swap (or something similar) on any of the data containers that might act as a channel swap? Preferably on the pixel cache?

Hi snibgo,

those code snippets look familiar - probably like what I've seen in other topics/searches. Like you though, I'm not sure how to transfer the command line into an api function call(s)!

Hi there dlemstra, nope. I'm trying to point another api's image object reference to the IM pixel cache. They both use the same data type. The other object isn't trying to take over ownership either - it just copies the container data in the order it's given. I can see thus far that it's 'working ...

Hi Folks, I'm unsure how to swap colour channels using the api. Searching Google brings up command line -swap based topics, but nothing using the API (can't find any swap() function?). Reason is for rearranging order of RGBA to ARGB. Don't need any pixel colour changes, just colour channel swaps ...

Hi folks, I've 'worked out' what the problem is here. See examples: // this fails Image Img1; Img1.read("C:\test.png"); // this works Image Img1; Img1.read("C:/test.png"); // note the difference is the folder characters ("\" and "/") Would be happy to hear from anyone who might be able to explain ...

That's no worries, thanks for having a go - I'll do a bit more testing with the demos and the command line at some stage to see if anything further can come out of them. In the meantime, I may have found a workaround that, while not the most efficient way, might do enough to at least continue with ...

Hi snibgo, development is being done in VS Exp. 2010, and the crashes are happening in release builds. I must confess, generally speaking, I don't do debug builds as I test most things manually myself by (e.g.) printing variable values etc. For notes' sake, the build ends up as a dll (albeit with ...

Hi Folks, when trying to init an image by reading from a file location, my program crashes. Here's what I've gone in circles around: InitializeMagick("..."); // tried a few locations from the program location, to null Image image; image.read("..."); // crash But if I init an image using: Image image ...

Hi there fubert (love the name :D )! I wasn't alerted to a reply. Thanks for posting a response. However, to usual PBert standards, I simply cannot get it to compile. Following the steps seems to get me further than before, but the build fails with 36 errors such as: LNK2019: unresolved external ...

Hi Folks, my apologies in advance for the lengthy post that follows - but I thought best to explain/cover my position as best as possible. I'm in the process of building a software plugin under another SDK environment (for Win and Mac, possibly Linux too). This software builds fine inside of VS 2010 ...
