Showing the position only with an active tool seems a bit confusing,
if you've opened up an image just to find out the coordinates of
a pixel for instance, there shouldn't be a need to have to select
a tool first.
Previously, we were ignoring the scale of the editor in the second
paint step. If you were zoomed in, the size while you were drawing
was not the same as the size of the final shape.

A previous commit I made broke layer dragging since the hole_index
was always being computed with respect to the top of the layer list
widget, however we were now drawing layers from the bottom. When
you didn't have enough layers to fill up the full height, dragging
them around would be weird.
This patch computes the hole index correctly using the same offset
we start drawing from, and fixes the behavior.
In addition to adding the action, this commit also makes the
`did_change_rect()` method take in an optional rect, which
represents the new rect position. By default it is the same as
`rect()`.
When we are cropping an image, we don't want to move the whole
cropped section to the top-left of the original image in the
ImageEditor widget, so this allows us to keep the cropped image's
position fixed.
We can now drag-and-drop files onto PixelPaint to be able to open
them. Each dropped file opens in a separate editor (which is the
default behavior of Photoshop).
Previously, all the UI setup was done in `main.cpp`, with a whole
bunch of lambdas,, and actions etc just being stored in the main
function. This is probably an artifact from back when it was first
created.
Most other applications now have a "MainWidget" class of some sort
which handles setting up all the UI/menubars, etc. More importantly,,
it also lets us handle application-wide events which we were
previously not able to do directly, since the main widget was just
a default GUI::Widget.
This patch moves all the core functionality of the PixelPaint
application into PixelPaint::MainWidget, which is then instantiated
by the main function. There is likely some more refactoring that
would help, but this commit is big enough as it is doing mostly
a direct port.
The fd would get closed when the File went out of scope, so we couldn't
open any file specified by 'pp <path to file>'. We need the fd to be
alive and we solemnly swear to take good care of it and close it
ourselves later.
Every tool that has a slider now registers the primary/secondary
sliders and now uses the same keyboard shortcuts to modify the
primary and secondary properties. `[` and `]` for the primary,
`{` and `}` for the secondary.
There are quite a few tools that might want to change certain values
based on consistent keyboard shortcuts. This commit allows tools to
hook up a "primary" and "secondary" slider with the base `Tool`
class, which can then handle updating those sliders with the common
shortcuts.
Note that any derived classes that want to override the `on_keydown`
function will manually need to call `Tool::on_keydown()`.
This new class will open and parse files (either images directly or .pp
project files) and one can get the parsed Image as well as other
information from it.
This patch removes a bunch of 'try_create_from..." methods from Image in
favor of using the ProjectLoader.
The only json_metadata that is available are Guides for now.
The ImageEditor knows more about the image than Image itself. So to save
a project with all the information known to the program about an image
it's logical that ImageEditor performs that task rather than the Image.
There isn't any additional data added yet, but now there's the
possibility to do so.
And also try_create<T> => try_make_ref_counted<T>.
A global "create" was a bit much. The new name matches make<T> better,
which we've used for making single-owner objects since forever.
This also required adding a new hook to `ImageClient`, since there
wasn't a way of telling the ImageEditor that the full rect of the
image has changed (as when we rotate).
If we don't have enough layers to be able to scroll, the layers
are pushed to be at the top of the layer list. This doesn't make
much sense now that we are correctly drawing the layers in the
right order, so now we draw them justified towards the bottom.
Previously we were also clipping the bottom gadget slightly when
there were enough layers to scroll. Now, I'm adding some offset to
the total height to account for this and give equivalent spacing
from the top and bottom layers.
Previously the background layer was shown at the top, and layers
in front of it were shown below it. This was really unintuitive.
This patch fixes LayerListWidget to now properly differentiate
between the index of a gadget, and the index of a layer, since they
are essentially mirrored. I chose not to modify the order in which
layers are stored since back-to-front makes it really convenient
there.
Previously it would only change the color of the ColorWidget itself,
but not make it the primary/secondary color. I think it feels nicer
this way, if I'm adding a color to the palette I likely want to use
it.
If you *really* need to only change the color of the palette, you
can just Ctrl+Middle click.
Previously, if you wanted to use a custom color, the only way to
do so was to first Ctrl+click on one of the pallette colors, which
would just change that palette item. Then, you would need to
manually click on that color.
Now, you can just click on the preview of the primary/secondary
color to open up the picker and only temporarily use the new color
without affecting the palette at all.
Only one place used this argument and it was to hold on to a strong ref
for the object. Since we already do that now, there's no need to keep
this argument around since this can be easily captured.
This commit contains no changes.
This way we can feed it the values if we wanted to change an existing
Guide and handle the default as before.
That we have to pass a String here is a bit ugly.
The height of the bottom color container was cut off at the bottom.
This adjusts the heights and also the primary/secondary color
widget so that it's in line.
Add a new Color category to the Filter menu. Add the Grayscale
filter under Filter->Color to turn the selected layer to grey colors.
Created GrayscaleFilter.h. Modify Filter.h to allow filters
without parameters.
The prior commits add the `DrawMode` enum to keep track of where
the shape is being drawn from. With this addition, the prior `Mode`
enum name is confusing, so this commit renames it to `FillMode` to
be more explicit :^)
Essentially the same logic as the prior commit, but now for the
`RectangleTool` class. Pressing `alt` lets you draw the rectangle
with the starting position as the center.
Like other common image editing applications, now if you press
`alt` while drawing an ellipse, it uses the starting position as
the center of the ellipse as opposed to one of the corners of the
bounding rect.
The EllipseTool class now keeps track of a `DrawMode`, which is
either `DrawMode::FromCorner` (default), or `DrawMode::FromCenter`
(the option added by this commit).
The `draw_using()` function was modified to now take in the start
and end positions and construct the `ellipse_intersecting_rect`
itself, since we need to construct it differently based on the
drawing mode.
Previously, if you used one of the keyboard shortcuts to select a
different tool, it didn't change the cursor to the corresponding
one till you clicked somewhere / did something else to trigger an
update. This was pretty jarring since there's no indication as to
whether the tool change was successful or not.
This patch just calls `set_override_cursor()` when a valid active
tool is set to immediately update it.
In general, I think `opt == x` looks much nicer than
`opt.has_value() && opt.value() == x`, so I'm updating
the remaining few instances I could find with some regex
magic in my search.
Some tools (e.g. ZoomTool) doesn't need layer to work. This commit
makes mouse events fire even if there is no layer. This fixes
a bug that ZoomTool didn't work when there is no layers.
This commit adds a Tool::MouseEvent struct, which contains events that
may be needed by tools: layer-relative, image-relative and raw (editor-
relative) event.
The raw event is used by ZoomTool to properly pan the view. This fixes
a bug which caused image to snap out of sight.
