Legacy ImageMagick Discussions Archive

I need to enlarge the image canvas by say adding 100 pixel rows repeatedly for about 10 times in C++. I know, there is good command line function -extent that can do the job I need.

Although, I develop my application in C++, I would like to know if there is anything that works like cmd line -extent parameter that would add a new empty image block to the existing image. It is important to mention, that I don't want to resize the existing grapics in the canvas, I just want to add more space for drawing to the bottom of it.

I have spent long time trying to find answer, because I came here. Indeed, how to -extent my image by say 100 pixels in bottom part, by adding background color, in C++ please?

Thank you and with regards,
Rene.

We'll add an extent() method to Magick++ within a few days. For now you would need to create a blank canvas image and append it to your image to extend an image.

Hello Magick,

thank you very much.

Was it your original plan to add extent() to Magick++, or will you do that because of my question?

Thank you anyway, and I am looking forward next release of ImageMagick.

Rene.

Our plan is to make all MagickWand methods available in Magick++ as time permits. In the mean-time you can access MagickCore methods directly in the MagickLib namespace (e.g. MagickLib::ExtentImage()) or wait until tommorrow and grab 6.3.2-0 Beta which has the Magick++ extent() method declared.

Hello Magick,

Thank you very much. It will be very good to have all the MagicWand functions available in Magick++.

Yes, That was my original plan, to use MagickLib::ExtentImage(); if Extent() was not available from Magick++.

Thank you again, and wish you a lot of succes with ImageMagick.

For your information only, there is another very competitive library called FreeImage (http://freeimage.sourceforge.net/) available, I did a close comparison of both, and I think, ImageMagick is far, far better.

With regards,
Rene.

http://www.imagemagick.org/script/changelog.php - this link claims, that there should be ImageMagick 6.3.2-0 available already, in January 16. 2007.

I went through several FTP sites offering ImageMagick for download, however, i did not find this version yet. Is there any primary download place where the most recent version is uploaded firstly, or do I have to wait several days, until the new version gets spread over the all FTP sites, please?

I checked forum as well, but did not find any relevant link, although search for "download" returned many results.

Thank you and with regards,
Rene.

You can find beta releases of ImageMagick here: ftp://ftp.imagemagick.org/pub/ImageMagick/beta.

Magick,

Thank you very much.

Have a nice day,
Rene.
