LazPaint (alpha-blending, antialiasing, filters)

[pstein]

Hello, I am new to LazPaint and have some questions:

1.) How do I merge a just (with Strg+V) inserted image into base image?
2.) When I save a *.jpg image: Where can I define the compression ratio for JPG?
3.) Ok, I can scroll big images by dragging them. But occasionally I want to use scrollbars.
     How can I add these scrollbars to LazPaint Window?
4.) How can I close a certain image WITHOUT exiting whole LazPaint?

Thank you

Hello pstein

1) I suppose you refer to pressing Enter to merge the selection
2) When you save a JPG, an option window is shown with a bar where you can select the quality percentage
3) Scrollbars are not implemented yet. Not that you can scroll with any tool by keeping Space key pressed and the dragging with the mouse.
4) For now, the closest to that is to create a new image. It has been requested that images have their own tab: https://github.com/bgrabitmap/lazpaint/issues/101

A new version of LazPaint is in testing. It is version 7.2:

EDIT: Windows Install too provided

Compilation and installation
This version can be compiled on Lazarus 2.2.2, BGRABitmap 11.5.1 and BGRAControls 7.6.

On Linux and MacOS, you need to install libwebp and libavif if you want to use WEBP and AVIF file format.

Bug fixes and improvements
This version of LazPaint contains a lot of bug fixes and minor improvements, in particular:
- language: tool shortcuts for Cyrillic keyboard
- file: handle path in file textbox
- file: added quick save action (Ctlr-Q shortcut)
- file: experimental support for AVIF format
- SVG: close path when export as SVG
- tools: disambiguation of shortcut keys (Y, K, F and R)
- deformation grid tool: handle extreme deformation
- layer tools: delete current layer with DELETE key
- text tool: provide text style, bidi mode, vertical alignment in toolbar
- polygon/closed curve tools: hide center point when ALT key pressed
- selection tools: deselect when ESCAPE pressed and selection layer empty

New key assignments
- Y : shaded shapes because next to U (rect/ellipse) and T (text)
- K : clone tool because similar sound
- F : select rect/ellipse because near D (rect/ellipse)
- R : swap color (R like reverse)

So here are all the key bindings (without Shift/Ctrl/Alt/Cmd)
