im creating a program that will search a directory for images and display them on buttons (wx.BitmapButton) on a grid (sizer) but im having problems getting the images to resize to fit the buttons, i can resize all the images by hand but i want to preserve the original images and not take up space with resized coppies of all the images, i will be continualy adding images to this directory and the size would get pretty big if i had to make coppies and resize all the images. what im looking for is a way to DISPLAY the images smaller, without having to MAKE the images smaller. any help would be greatly appreciated.
thanks
Justin
Have you tried Andrea’s
http://xoomer.alice.it/infinity77/eng/ThumbnailCtrl.html
maybe it does what you need.
If you still want to use your own implementation… I suggest keeping some kind of thumbnail database, the resized images are not all that big…

i have looked into Andrea’s widget and it looks promising but i need the resized images to be placed on a button and i dont think that i can do that with ThumbnailCtrl. i know that the thumbnail images are not that big but i was trying to avoid writing the code to copy and convert the images when they are inputed into the program.

Have you looked into wx.wxArtProvider and the method GetBitmap?
Look that the wxPython Demo application and the wxTreeCtrl for an example. The third parameter takes (w,h)

maybe I'm missing something, but this is pretty trivial:
load the image into a wx.Image
I = wx.Image(filename)
resize it
I.Rescale(NewWidth, NewHeight)
turn it into a bitmap
B = wx.BitmapFromImage(I)
put it on the button
Button = wx.BitmapButton(parent, bitmap= B)
presto!
