Image Processing Magic

It's a bit frightening what image processing "magic" can do to a picture: Original: Processed: And that's not even advanced "magic" but some rather simple code written in Delphi (most of which I can't publish here unfortunately). What it does is: Smooth brigthness by applying a brigthness map. Adjust for lens edge blur by selective … Continue reading Image Processing Magic →

Extend the event OnClick of all MenuItems in the screen to execute another block of code

Shameless self promotion: On StackOverflow somebody asked the question in the title and I answered it. And as you might have guessed, I am mighty proud of having had that idea. It might be interesting to know that this is how GExperts fixes some of the IDE bugs and enhances some forms: It creates a … Continue reading Extend the event OnClick of all MenuItems in the screen to execute another block of code →

Things that every desktop program should do

There are a few things that every single one of our internal programs should do: Every dialog should be sizeable if it makes any sense at all.

dzEditorLinendsFix 1.0.4 released

This is nothing to write home about, really, just a small change: Previously when starting the tool, the main window was shown for a short time before it got hidden. Now that no longer happens. Don't now what this is about? You are probably lucky then and don't need this tool. But if you still … Continue reading dzEditorLinendsFix 1.0.4 released →

GnuGetText.pas using Utf8ToUnicodeString instead of Utf8ToWideString

A few weeks ago, Sue King contacted me because there was a problem with using dxGetText together with the Nexus DB components. For Unicode aware Delphi versions gnugettext.pas declares a function utf8decode which calls System.UTF8ToWideString. After replacing a call to utf8decode with UTF8ToUnicodeString the problem went away. Since I don't want to break backwards compatibility … Continue reading GnuGetText.pas using Utf8ToUnicodeString instead of Utf8ToWideString →
