📫 RubberStamp is an Android library that makes it easy for you to add a watermark to your images.

rubberstamp's Issues

Ability to specify text style

There are a lot of different text styles (bold, italics, etc). The user of this library should have the ability to specify the style that he wants. It would also be useful to specify other text attributes like shadow, rotation, etc.

Ability to auto size the text

It would be useful if there was a way to set the text to be auto sized if the text has been specified which will be the case almost always.

Have ability to autosize the watermark

It would be nice to be able to stretch the watermark automatically across the bitmap after the text has been specified.

Proposal

If the watermark is too long, can you add automatic wrap？

Ability to let the rubber stamp be a bitmap/drawable

It would be super useful if the rubber stamp could be another drawable or bitmap instead of supporting just a text.

add lines of text watermark

how do I add three line(s) of text rubber stamp one by one to a bitmap in BOTTOM_RIGHT position? i have used "\n" in the text content but it doesn't work. please help

OutOfMemoryError

When I use RubberStamp to add a watermark to a 3120x4160 6.62MB image，I got the following crash log。

Do I have to reduce the size of the picture?

Adding the ability to tile watermarks

It would be awesome if the library could provide the functionality of tiling a watermark. I think this should override the position provided as it would be covering the entire bitmap. An example of this would be the following:

Make use of a BitmapPool for better memory efficiency

Add padding/margin to the rubber stamp

It would be great if there was some way to specify some sort of a padding/marging in addition to the RubberStampPosition. Right now the rubber stamp would stick to the edges if I give it a position like BOTTOM_RIGHT. Padding/Margin would be a great addition to this functionality.

Do the work on a background thread

It would make sense for the library to handle the bitmap creation part on a background thread instead of expecting the developer to make the addStamp call on a separate thread.

Fix watermark position issue

When the watermark is provided as a bitmap, it does not draw the watermark at the appropriate location.

More faster and more format supported?

Is it possible to add YUV supported?
Is it possible to add watermark on jni without decode bitmap?

How to get URI after adding stamp?

Is there any method If I can get the image URI after stamping?
