Thanks. Just to check, are those made with the master branches? I have changed some things in the dev branches of BGRABitmap, BGRAControls and LazPaint but that's for next releases.

Yep dev-branch, so I need to do the build again.

Ok. What error did you get when making the DMG file?

Well you've fixed it.  :) For the people reading the forum: it was that I ran the script drag and drop in the console, so the path was not set, relative path was wrong and can't find the resources.

Thanks for pointing that problem because fixing it is better as it was a bit dangerous for the scripts to do stuff in a random folder

Hi Circular, thanks you for the new release.
I experiment some problem using gradient:

I have 2 layers, the first with a drawing and the second empty.
On the empty one, I would like to draw a linear gradient with color picked up from the first.
So, I select the first layer and with the color picker tool, LEFT CLICK to take the forward color and RIGHT CLICK to take the back color. All is right, the color are right selected in the top tool bar.
When I use RENDER GRADIENT tool on the second layer, the color aren't the previously selected ones.

Do I have missed something ?

Hi Lulu  :)

In version 7, the pen and the background can have different gradients. For example, you can set a gradient for the filling of a rectangle (back color) and a different one for the pen.

For the gradient tool, the gradient is specified in the back color. The pen color is not used in this case.

First way (copy/paste color definition):
- make sure the color window is displayed
- select the back color by clicking on its preview in the top toolbar
- using the color picker, for each color, pick it with right click and copy/paste its text definition into a text editor (for example #ff0000 for red)
- choose the gradient tool
- in the top toolbar, you have a preview of the gradient. Click on the left part to select the start color, paste the definition by right-clicking the text box and select Paste. Same with right part for end color.

Note: you cannot do Ctrl-V because that's for pasting images and shapes. That could be improved I guess, because if you are editing the color, you would rather want to paste text into it.

Second way (using palette to store colors)
- make sure the palette is displayed (on the right) and the color window as well
- select the back color by clicking on its preview in the top toolbar
- empty the palette to make it easier to find the colors (using palette menu button)
- using the color picker, for each color, pick it with right click and add it to the palette (top-left button of the color window)
- choose the gradient tool or any drawing tool
- do Ctrl-Left click in the palette to select start color and Ctrl-Right click to select end color

It feels like it could be simplified.

I do it with the second way.
I don't knew the use of the two buttons in the color window. May be, add a hint on them will be more explicit for the user ?
Thanks for your help :)

You're welcome.  :)

Indeed, there was those hints but they disappeared. I have put them back on dev branch.

EDIT: I've applied the changes of issue #207 on the dev branch.

If it is not reported already, I came across to a newly introduced bug in LazPaint 7.1.5:
When I rotate and image to 90 degrees, the image is rotated, but the old image is also shown, until some action is performed with the image.


Also, it would be good if 180 degrees rotation was available in the menu, instead of having to do rotate 90 degrees twice.

Edit: I just found out that resizing the image to a smaller one leads to the same issue- both greater and smaller image are shown.

Thanks CM360 for reporting it. I fixed it on dev.

I've added 180 degrees rotation by the way.  :)
