Hi, I need a system that lets users draw scribbles on top of other users images. This will be very useful on my board for creative people.
The file-system is phpbb2 with SQL and the Attachment mod is used for uploading images(attachments). The users can upload other files than images so the scribbler has to check if the attachment is an image or not before it shows up.
If the attachment is an image and the user has rights to add scribble a button "add scribble" shows up in the top of that post.
When clicked a MS Paint lookalike panel and drawing-board shows up. Please see attachment! This can look different. It needs only very basic drawing tools like line, brush etc. More colors is nice. Open for suggestions.
It must store scribbles on the server in small files. Caching(?) and as small files as possible. No super heavy cpu-load every time someone wants to see a scribble.
When someone has made a scribble it shows up in a new post. The attached image is loaded from the same location as the original but the scribble is now on top as an layer. It can be turned on and off with buttons underneath.
PLANB, if this is impossible the image+scribble is saved on server as new image.
If the user wants to make a scribble and the user has multiple attachment images in his post it must be possible to select the image you want to scribble on. Either with a radio-button, dropdown list, hoovering above the image and selecting it or some other solution. Open for suggestions!
The new image+scribble needs to have a delete button around it so admin and moderators can remove it(from post and server).
(This is also where the on/off button is)
See the attachment.
The resolution on image attachments vary so the scribble-board needs to scale itself to the image attachment and get stored and show up in the same resolution. This is important. The attachment and scribble must be lined up.
To reduce server load it could have an max size-limit for scribbles. Either deactivate it for larger images than an limit set by admin. Or scaling of the attachment so it fits a smaller scribble-board.
•Admin and moderators can delete scribbles.
•Option to activate scribbles in selected categories.
•Option to select group that can create new scribbles.
•Option to select who can see scribbles.
All this can be hardcoded(no need for AdminControlPanel). This last option is most for hiding it for guests if it gets heavy.
The scribbler only work on attachments uploaded with the attachment-mod.
I can create buttons and graphics needed. And i will help you with any questions and other support on the way.
The site is live but working directly on the site is okay with some planning. My board is in Norwegian but i will help you out with creating test-users aso.
I know there is more ways to reach the goal of this. So i am open for suggestions and ideas.
There was an scribble-mod for phpbb2 back in the days. The original author of this was so kind to send me all the files and a more advanced version. It is coded in Java. It does NOT have the drawing on images feature but it has a lot of the phpbb-stuff and it can make and save drawings. So this can be helpful for setting this up. The drawing app does not need to bee Java. But not Flash please. Want it to show up on phones/ ipads if possible.
Please take a look at the attachment. It explains alot. Hope to get in touch with some smart coders here. Thanks.
