-
- Pinboard rom patch is a patch for the pinboard.
-
- The following new features are implented:
-
- Fixes bug when dragging a group of selected icons with adjust.
- Previously, if you dragged a group of selected icons with adjust, it
- would drag all but the icon dragged on.
-
- Allows dragging of iconised window icons with adjust.
- Previously only select worked and adjust was just ignored.
-
- Fixes always claiming window closed messages.
- Whenever a window closes, the window manager broadcasts a message to tell
- applications. It is only used by pinboard like applications, so the
- pinboard always claimed it. But some patches need to use it.
-
- Adds auto saving of pinboard state on shutdown.
- If the system variable SavePinboard$State contains a valid path, the
- current state of the pinboard is saved to that file when the computer is
- shut down.
-
- Adds support for JPEG backdrops.
- JPEG files can now be used as backdrops and are rendered in real time.
-
- Fixes bug in detecting mode change.
- Previously the pinboard would sometimes fail to redraw the screen when
- the mode changed, that could cause a scaled backdrop to stop filling the
- screen.
-
- Fixes bug in spriteextend.
- Previously spriteextend would fail with an address exception error if you
- tried to render a JPEG while the current wimpslot was less than 24k.
-
-
- Installation:
- -------------
-
- ***NOTE***: If you have an existing version of my pinboard Rom
- Patch, you must remove it completely before continuing, as the
- installation method has changed. To do this, delete the obey file
- called !PinPatch that you installed in either your predesk or tasks
- directory. Then delete the directory PinROMPatch in your
- !Boot.Utils directory.
-
- First, copy the whole !PinPatch application into your
- !Boot.Choices.Boot.Tasks directory. (Users with RiscOS 3.7 or later
- can put it in their !Boot.Choices.Boot.Predesk directory instead if
- they wish).
-
- RISC OS 3.50 users only: If you have Acorn's ROM patch on your
- system (it will be called !ROMPatch in your
- !Boot.Choices.Boot.Tasks directory). Then you must rename it to
- !!ROMPatch (add a !). This is to ensure that it is run before
- pinboard ROM Patch.
-
- Finally reset the machine and it should all be installed.
-
- In the unlikely event that something goes wrong, you may find that
- your machine refuses to start, getting as far as the startup screen
- then crashing. If this happens, reset the machine holding down
- shift (press control + shift + break). This will start the machine
- without running the boot sequence. You can then go into !Boot and
- remove the files you have just added, restart the machine and try
- again.
-
- It is possible to test it first to see the effect. To do so just
- double click on the !PinPatch application and it will be
- temporarily installed.
-
-
- Frequently Asked Questions
- --------------------------
-
- 1) I have found a JPEG that doesn't appear to work as a backdrop, what should I do?
-
- Firstly, you should try loading it into draw. If it doesn't work there, then
- it's format is incompatible with the JPEG rendering module. Load it into
- ChangeFSI and save it out again as a JPEG and it will be converted to the
- correct format.
-
- 2) I am trying to use a tiled JPEG backdrop, but the JPEG is rendered much
- smaller than it should be, why?
-
- This is caused by an incorrect header in the JPEG. I have found quite a
- large number of JPEG files that have incorrect DPI settings. For the moment,
- the only solution is to pass the JPEG through ChangeFSI, that will cure the
- problem. A future version of the patch will probably fix this.
-
-
-
- Removing:
- ---------
-
- The patch can be removed at any time by pressing F12 and typing
- RMKill PinboardROMPatch
-
- NOTE: before RMKilling the patch, you must remove the backdrop if it is a JPEG.
- failure to do so will cause the machine to crash.
-
- To permanently remove it you should delete the !PinPatch
- application that you installed in your boot sequence.
-
-
- Auto state saving
- -----------------
-
- To automatically same the pinboard state at shutdown, set the variable
- <SavePinboard$File> to point to a valid file. The state will then be saved to
- that file on shutdown.
-
- For example:
-
- Set SavePinboard$File Boot:Choices.Boot.Tasks.PinBoard
-
- will make the state be saved on shutdown and reloaded automatically on startup.
-
-
- NOTES:
- ------
-
- 1) If you are using one of Acorns rom patches then that must be run before my
- patch. If it is installed according to the standard instructions then
- there should be no problem.
-
- 2) This patch will only work on RiscOS 3.5 to 3.71. It is not
- possible to run it on prior bersions of the operating system due
- to limitations of the hardware.

- Other Rom Patches:
- ------------------
-
- I hope for this to be one of several rom patches I will produce. Now I have written
- one it is relatively easy to adapt it to other purposes. So, if anyone has another
- patch that would benefit from converting into a rom patch, I would like to hear
- from you.
