TI3333 - Installing JPEG Components that Ship with Delphi 3
- Product: Delphi
- Version: 3.x
- Platform: Win32
Q: How do I install the JPEG components that ship with Delphi 3?
A: Below, you'll find step by step instructions on doing this.
Step 1 - Copying the JPEG files to your hard drive
Insert your Delphi 3 CD in your CD-ROM drive.
In the Explorer, browse to the INFO\EXTRAS directory.
To copy the JPEG folder, drag and drop it from the Explorer to
another folder, e.g. C:\MyStuff.
All the JPEG files should now be in C:\MyStuff\JPEG.
To make thing easier for us, now copy all the files from the
C:\MyStuff\JPEG\OBJ folder to the C:\MyStuff\JPEG folder.
Do this by, in the Explorer, selecting all the files in the
C:\MyStuff\JPEG\OBJ. When all files are selected, right click
and choose Copy. Then browse to C:\MyStuff\JPEG and choose
Paste.
Step 2 - Installing the JPEG components
Launch Delphi 3.0
From Delphi's main menu, select Component | Install Component
You'll should now see the "Install Component" dialog.
Hit the Browse button next to the Unit file name box.
In the "Unit file name" dialog, browse to C:\MyStuff\JPEG.
Select the file named JPEG.PAS and hit Open.
The Unit file name box should now be filled in properly.
Make sure the Package file name is set to the Delphi User's
Components package, which by default is in this location:
C:\Program Files\Borland\Delphi 3\Lib\dclusr30.dpk
Hit OK.
You'll now see a "Confirm" dialog, saying that the package
will be installed.
Hit Yes.
You should now see an "Information" dialog, saying that the
package is installed.
Exit the package editor and make sure you save the changes
to the package.
Step 3 - Using the JPEG component
Simply drop down a TImage and load a JPEG into the Picture
property. Also, make sure the JPEG unit is in the USES clause,
so that the JPEG stuff is registered at run-time.
