photoshop text overflow

thanks xbytor2, will give this a whirl. I dont know how but i did get the horizontalscale to reduce, But since sleping its gone. I cant recall if it was horizontalscale = -1 or horizontalscale.value = etc. but thanks for your input. i hope to return with good news.

I've solved a related problem in doing contact sheet thumbnail captions. In my case, I know the bounds of the caption and need to fit the name of the image in that bounds. If I can't scale it to fit, I truncate it and append '...' until it fits. The performance is not what I would like, but it's not unreasonable. ContactSheetII.prototype.insertCaption = function(doc, csOpts, bnds, file, image) {

var self = this;

if (file == undefined) {

file = File(image.name);

}

var caption = decodeURI(file.name);

if (csOpts.captionFilename) {

if (csOpts.noExtensions) {

caption = file.strf("%f");

}

} else {

caption = '';

}

// LogFile.write("Inserting caption " + caption + " at " + bnds);

app.activeDocument = doc;

var layer = doc.artLayers.add();

layer.kind = LayerKind.TEXT;

layer.name = decodeURI(file.name);

var titem = layer.textItem;

if (csOpts.autoscaleCaptions) {

titem.minimumGlyphScaling = 50;

titem.desiredGlyphScaling = 100;

}

titem.contents = caption;

if (!csOpts._fontColor) {

csOpts._fontColor = psx.colorFromString(csOpts.fontColor);

}

titem.color = csOpts._fontColor;

titem.size = csOpts.fontSizePX;

titem.font = csOpts.font;

titem.kind = TextType.PARAGRAPHTEXT;

var captionWidth = bnds[2]-bnds[0];

// Check to see if the caption is too wide

var twidth = Math.round(titem.width);

if (csOpts.autoscaleCaptions) {

// try to scale the glyph width to make it fit

if (twidth > captionWidth) {

if ((captionWidth / twidth) > 0.5) {

titem.desiredGlyphScaling = (100 * captionWidth) / twidth;

} else {

titem.desiredGlyphScaling = 50;

}

}

// switching the kind forces PS to recompute the text size

titem.kind = TextType.POINTTEXT;

titem.kind = TextType.PARAGRAPHTEXT;

twidth = Math.round(titem.width);

}

if (csOpts.dotTruncate) {

// truncate the text until it fits

if (twidth > captionWidth) {

if (caption.length <= 4) {

// handle the deviant case here

titem.contents = caption[0] + '...';

} else {

// estimate the string length...

var len = Math.round((captionWidth/twidth) * caption.length);

var str = caption.substring(0, len-4) + '...';

// take off the file extension first

while (twidth > captionWidth+4) {

titem.contents = str;

if (str.length <= 4) {

break;

}

titem.kind = TextType.POINTTEXT;

titem.kind = TextType.PARAGRAPHTEXT;

twidth = Math.round(titem.width);

str = str.substring(0, str.length-4) + '...';

}

}

}

}

titem.justification = Justification.CENTERJUSTIFIED;

titem.width = bnds[2]-bnds[0];

titem.position = [bnds[0], bnds[1]];

var style = csOpts.captionStyle;

if (style && style != CSII.NO_CAPTION_STYLE) {

layer.applyStyle(style);

}

return layer;

};
