[Note] About the small zoom-steps…
Posted: Sat Feb 10, 2007 12:06 am
Hello !• Now, we may use a zoom-step from 1% up to 99%, that's nice
- However, the 1% step use could look strangely in some cases…
• This is related to this thread - bug fixed for the black BG in a test version-
- While testing for that bug, I noticed that the small images were not enlarged on the screen when using a 1% zoom step,
up to a certain number of “Zoom in” strikes (where the bug occured).
• In fact, this is normal, since the image must be enlarged enough to get at least one more pixel
representing n…1% (fractions of 1 pixel) of the largest side.
- So, to use 1% and see the image growing on the screen at the first Zoom +, the minimal size is indeed 100*100 pixels.
- With a 50*50 image, we need two strikes, with 25*25 four strikes etc.
- In the opposite, using 2 % the minimal size is 50*50… and so on.
- For “standard” Win icon sizes - always an even amount of pixels and multiples of 8¦16 - there are some calculation rounds,
hence this is not absolutely true…
- Same for i.e. 99*99 (behaves as 50*50), while we'ld expect rather it behaves as 100*100,
since it's greater than the average (75*75).
