Read in the images and save as a GIF, and they will animation.
images should be the same size.

For more detail see IM examples on animations (see my signature)

yes that can be done. The problem is finding the right 'sparkle' overlay. I looked at the given image and it is so optimized, it is basically imposible to extract the sparkles from this image. PS: I am playin around with a sparkle 'star' generator. My experiments can be seen at... Tilable Stars and ...

Their is no easy way to frame an image with a repeating edge tile pattern. What I have outlined (particualrly the extended parts for scaling the tiled addition to fit the image better, is probably the best result overall. The corners are no problem, it is fiiting the repeating pattern into a fixed l...

Did you look at thumbnail creation for IM examples (see signature) Also if you are dealing with GIF animations, that is a lot more trickier as it is multiple images (or image parts). See the animation section for the deails of this. Most thumbnails fro animations are often either scaled versions of ...

A blob to my understanding in just a copy of the actual image format file that would have been saved, but saved into a memory string. That is it should be just a string. in some API's that may be a special type to also specify the strings length, so check your API.

Of course the words were not wrapped. You did not specify you wanted word wrapping too! Label will only us ethe text as given (including newlines now) but will NOT word wrap. If you give a size then that size is used in the result, and the font is scaled to fit that size. if only a pointsize is give...

Topic: Convert TIFF with annotations to JPG
Replies: 1
Views: 10700

It sounds to me that it is more likely that windows is adding an extra 'meta-tag' to the TIFF image (which is a hack of such meta-tags). Naturally IM does not understand or even try to understand all these extra unknown tags. I suggest you annotate the text with IM so it gets directly drawn onto the...

Kepp trying to reduce the quaility setting until you get what you want.

The JPEG image sounds like it does not compress very well.
One improvement would be to blur the image very very slightly.

IM provides no such method. The problem is that IM has no way of known just how big the final image size on disk will be given the various compressions, quality, image size, color space, and file format the image is actually using. It is imposible to pre-determine, except posibly as a guess-timate, ...

The four values are the X and y of the center and teh x and y of a point on the edge of the circle. If you have a radius you can just add the redail to either the x or y of the center value to get a point on the edge. Eg circle at 50,50 with 30 pixel radius... add 30 to the x value of the center giv...

You can now create a label at a specific size!

See label: in IM exmaples
http://www.cit.gu.edu.au/~anthony/graph ... ext/#label

Just specify a -size for the label and don't give a -pointsize. IM will then find the best pointsize to fit that sized image.

This was added in version 6.2.5
