how to preview images inside a dialog box?
Hello Everyone,
Is there a way to preview images inside a dialog box in photoshop MacOS? I tried a lot of ways to do it but I am always stuck with Error 509: Invalid image data.
Not sure if photoshop allows it. Please help. I have also dropped some of the scripts I explored.
Method 1:
#target photoshop
// create a new dialog window
var dlg = new Window("dialog", "Image Preview");
// create a panel to hold the image container
var panel = dlg.add("panel", undefined, "Preview");
// create an image container inside the panel
var defaultImage = new File("~/Desktop/placeholder.png"); // change to the path of your default image file
var imageContainer = panel.add("image", [0, 0, 300, 300], defaultImage);
// create a button to open an image
var button = dlg.add("button", undefined, "Open Image");
// set the dimensions and alignment of the dialog box elements
button.size = [100, 30];
button.alignment = "center";
panel.alignment = "center";
panel.margins = [10, 10, 10, 10];
imageContainer.alignment = "center";
// define a function to handle the button click
button.onClick = function() {
// open a file dialog to select an image
var file = File.openDialog("Select an image", "*.jpg;*.jpeg;*.png");
if (file) {
// set the image container to display the selected image
imageContainer.image = ScriptUI.newImage(file);
}
}
// display the dialog box
dlg.show();
Method 2:
function main() {
inputFolder = Folder.selectDialog("Please select the folder with Files to process");
var fileList = inputFolder.getFiles(/\.(jpg|jpeg)$/i);
Image.prototype.onDraw = function () { // written by Marc Autret
// "this" is the container; "this.image" is the graphic
if (!this.image) return;
var WH = this.size,
wh = this.image.size,
k = Math.min(WH[0] / wh[0], WH[1] / wh[1]),
xy;
// Resize proportionally:
wh = [k * wh[0], k * wh[1]];
// Center:
xy = [(WH[0] - wh[0]) / 2, (WH[1] - wh[1]) / 2];
this.graphics.drawImage(this.image, xy[0], xy[1], wh[0], wh[1]);
WH = wh = xy = null;
};
var win = new Window("dialog", "Image test");
win.pnl1 = win.add('panel', undefined, undefined, {
borderStyle: 'black'
});
win.pnl1.preferredSize = [200, 200];
win.Im1 = win.pnl1.add("image", undefined);
var imageFile = new File(fileList[0]);
win.Im1.image = imageFile;
win.Im1.size = [180, 180];
win.pnl2 = win.add('panel', undefined, undefined, {
borderStyle: 'black'
});
win.pnl2.bu1 = win.pnl2.add('button', undefined, 'Next');
win.pnl2.bu2 = win.pnl2.add('button', undefined, 'Previous');
win.grp100 = win.add('group');
win.grp100.bu1 = win.grp100.add('button', undefined, 'Cancel');
var PIC = 0;
win.pnl2.bu1.onClick = function () {
//Next picture
if (PIC == fileList.length - 1) return;
PIC++;
win.Im1.image = File(fileList[PIC]);
};
win.pnl2.bu2.onClick = function ()
//Previous
{
if (PIC == 0) return;
PIC--;
win.Im1.image = fileList[PIC];
}
win.show();
}
main();
Thanks in advance.
