[Newbies] Customizing wrapping in TextMorph
Hi, I want to change the text-wrapping that is done in TextMorph (wrap after all non-letter characters (not only spaces), don't force-wrap long words). I could not find where or how the wrapping is actually done in TextMorph. Any pointers where I should look?

Re: [Newbies] Resizing a form to specific width and height
Hi Bert, thanks for your hint. I tried WarpBlt classrotate:degrees:center:scaleBy:smoothing: and it worked as expected. But I also found that I just had a slight mistake and my initial try with FormmagnifyBy: and aPoint (with x and y scaling) was actually also successful. I am using this now. Thanks, Matthias P.S.: I had to fix FormmagnifyBy: in my Squeak version as it initially did not work with Points as advertised.

Forms are fixed-size. The way you do it is by creating a new form of the desired extent and depth, and then copying (a part of) the old form into the new form, possibly scaling the pixels while doing so. This is done by class BitBlt (for bit block transfer) and its extension WarpBlt (which can do scaling and rotation too). There are convenience methods hiding the details of form creation, BitBlt, and WarpBlt in class Form. E.g. copy: aRectangle does cropping, and magnify: aRectangle by: aPoint smoothing: anInteger does cropping and scaling. BitBlt also does bit-depth conversion, color-remapping, statistics, and other image manipulations. It's well worth learning about :) - Bert - ___ Beginners mailing list Beginners@lists.squeakfoundation.org http://lists.squeakfoundation.org/mailman/listinfo/beginners -- Matthias Korn Institut für Wirtschaftsinformatik Fachbereich 5 Universität Siegen Telefon: +49 (0) 271 / 23 67 660 Mobil: +49 (0) 176 / 700 17 17 8 Uni: +49 (0) 271/ 740 - 3382 eMail: matthias.k...@uni-siegen.de ___ Beginners mailing list Beginners@lists.squeakfoundation.org http://lists.squeakfoundation.org/mailman/listinfo/beginners

Re: [Newbies] Coloring images with transparant parts
Hi Bert, I have quite a hard time understanding how to use color maps. And I really did not find any helpful documentation on them for Squeak. One example I found in the image is in BitBlt classexampleColorMap. But I don't know how to use it with a Form/BitBlt, well, and what the heck they are actually doing there... In most occasions they used the Bitmap class instead of ColorMap and I couldn't find anything to convert. Could you provide a simple code example on how to modify the color map of a Form?

I already tried to fileIn a minimal part (one Morph class) of the
application I want to port and started resolving the errors in the

Metaclass(Object)doesNotUnderstand: #category

Were there some changes in the Metaclass between V2 and V3 that explain
this error?
Thanks for the hint, though Karl. I didn't know about that possibility.

Hi,
in FileList you can try to look at the code with the CodeBrowser.
Select the file you want to load, press the code button, or select
browse code from the context menu.
This will load the code in a temporary way and you can browse it and
see the methods that change, and file in the parts you want.
