Step 1: Create Icons For The Package

  • Size of PNG file should be 24x24
  • You may need to compile lazres at first use. Simply open the lazres.lpi in the IDE and at the menu click run > build.

To create the lrs file run (where samplepackage is the name of your package and TMyCom is the name of your component): 

~/lazarus/tools/lazres samplepackage.lrs TMyCom.png

You can add more than one image to the lrs file by appending the image filename at the end. Eg. ~/lazarus/tools/lazres samplepackage.lrs TMyCom1.png TMyCom2.png ...

Following is a sample of the samplepackage.lrs file. 

LazarusResources.Add('TMyCom','PNG',[
  #137'PNG'#13#10#26#10#0#0#0#13'IHDR'#0#0#0#24#0#0#0#24#8#2#0#0#0'o'#21#170#175
