你可以使用 src 方法来将图片设置给图片浮动对象元素, 图片浮动对象元素的 src 可以设置 base64 格式的图片。
你可以通过 pictureStretch 方法来改变图片的布局。 pictureStretch 的类型是 ImageLayout 枚举。并且你可以使用 getOriginalWidth 和 getOriginalHeight 方法来获取图片的原始宽度和原始高度。
你也可以设置图片的边框； 边框的设置和标准 DOM 的边框设置一样。例如：
如果图片的部分地方有透明， 你可以通过设置 backColor 来获取或者设置图片的背景色。例如：
window.onload = function () {
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"));
initSpread(spread);
};
function initSpread(spread) {
var sheet = spread.getSheet(0);
var picture = sheet.pictures.add("f2", "$DEMOROOT$/spread/source/images/spreadLogo.png", 50, 50, 100, 100);
picture.backColor("black");
document.getElementById('pictureStretch').onchange = function (e) {
var sheet = spread.getActiveSheet();
var pictures = sheet.pictures.all();
var stretch = parseInt(e.target.value);
if (pictures) {
for (var index = 0, len = pictures.length; index < len; index++) {
var picture = pictures[index];
if (picture.isSelected()) {
picture.pictureStretch(stretch);
}
}
}
};
document.getElementById('borderStyle').onchange = function (e) {
var sheet = spread.getActiveSheet();
var pictures = sheet.pictures.all();
var borderStyle = e.target.value;
if (pictures) {
for (var index = 0, len = pictures.length; index < len; index++) {
var picture = pictures[index];
if (picture.isSelected()) {
picture.borderStyle(borderStyle);
}
}
}
};
document.getElementById('set').onclick = function () {
var sheet = spread.getActiveSheet();
var pictures = sheet.pictures.all();
var borderColor = document.getElementById('borderColor').value;
var borderWidth = parseFloat(document.getElementById('borderWidth').value);
var borderStyle = document.getElementById('borderStyle').value;
var borderRadius = parseFloat(document.getElementById('borderRadius').value);
var backColor = document.getElementById('backColor').value;
var pictureStretch = parseInt(document.getElementById('pictureStretch').value);
if (pictures) {
for (var index = 0, len = pictures.length; index < len; index++) {
var picture = pictures[index];
if (picture.isSelected()) {
picture.borderColor(borderColor);
picture.borderWidth(borderWidth);
picture.borderStyle(borderStyle);
picture.borderRadius(borderRadius);
picture.backColor(backColor);
picture.pictureStretch(pictureStretch);
}
}
}
sheet.repaint();
};
document.getElementById('resetPicture').onclick = function () {
var sheet = spread.getActiveSheet();
var pictures = sheet.pictures.all();
if (pictures) {
for (var index = 0, len = pictures.length; index < len; index++) {
var picture = pictures[index];
if (picture.isSelected()) {
var originalWidth = picture.getOriginalWidth();
var originalHeight = picture.getOriginalHeight();
if (originalWidth > 0 && originalHeight > 0) {
picture.width(originalWidth);
picture.height(originalHeight);
}
}
}
}
sheet.repaint();
};
};
