CenterGravity not working.

[rpatelob]

Code: Select all

convert ./cylinderize_1_20264.mpc -gravity center -crop 2000x443.089+0+0 +repage ./cylinderize_1_20264.mpc

Code: Select all

 MagickSetImageGravity(wand, CenterGravity);
    MagickCropImage(wand, 2000, 443, 0, 0);
    MagickResetImagePage(wand,"2000x443+0+0");
    MagickWriteImage(wand,"Fred_single_color1_36.png");

But somehow MagickSetImageGravity isn't working.

MagickCropImage() isn't sensitive to gravity.

How can I do it then?

A bit of a pain but could you write some code to calculate the co ordinates for the crop?

Could you please check http://stackoverflow.com/questions/4347 ... ot-working link? There is a source image too

As Bonzo says, you need to calculate the x and y offsets.

To centralise the composite, the x-offset is the difference in the image widths, divided by two. Likewise for the y-offset.

Yes, I did that as an alternate option, as gravity creates a problem. Thank you!
