Hi Was this a very dumb question or does no-one know? If it was a dumb question, please do point me in the right direction. :-) Otherwise, has no-one had any experience with a some image processing in Lazarus? I guess I don't really need this answered anymore... I was busy with a program in Java and wondered if I could rather do it in Lazarus. The progress was much faster but the image thing stopped me. Now I have the program almost done in Java... but, it would be a good idea to get some more documentation on the wiki about images. I literally found only that one bit of information that I mentioned in my other post.

Hello, I am storing filenames of pictures in a database and would like to have a TListView type control that can show it as icons or in report mode. (I guess I can use a DBGrid for the report view). I can't find any DB-aware component to show a list of images from a database, so I thought I will try and use a TListView and load the data from the database. Then I read an article in the forum somewhere saying that the listview complains if the images are different sizes. So I thought it is maybe a good idea anyways to create thumbnails of the images and save the thumbnails in the database as blobs. Sorry for the long train-of-thought thing. :-) So, my questions: * What is the best way to show a list of pictures - or rather thumbnails of the pictures? Are there any examples out there? * How do I resize a picture? I saw on the wiki ( http://wiki.lazarus.freepascal.org/Developing_with_Graphics#Resizing_the_bitmap_of_a_TImage) that I can do it by setting the height and width of the bitmap, but this causes strange results.
